This placeholder needs to have its +width and height set as explained in the [README](README.md) (go read that now if +you haven't, it's short). The plot will modify some properties of the +placeholder so it's recommended you simply pass in a div that you +don't use for anything else. Make sure you check any fancy styling +you apply to the div, e.g. background images have been reported to be a +problem on IE 7. + +The plot function can also be used as a jQuery chainable property. This form +naturally can't return the plot object directly, but you can still access it +via the 'plot' data key, like this: + +```js +var plot = $("#placeholder").plot(data, options).data("plot"); +``` + +The format of the data is documented below, as is the available +options. The plot object returned from the call has some methods you +can call. These are documented separately below. + +Note that in general Flot gives no guarantees if you change any of the +objects you pass in to the plot function or get out of it since +they're not necessarily deep-copied. + + +## Data Format ## + +The data is an array of data series: + +```js +[ series1, series2, ... ] +``` + +A series can either be raw data or an object with properties. The raw +data format is an array of points: + +```js +[ [x1, y1], [x2, y2], ... ] +``` + +E.g. + +```js +[ [1, 3], [2, 14.01], [3.5, 3.14] ] +``` + +Note that to simplify the internal logic in Flot both the x and y +values must be numbers (even if specifying time series, see below for +how to do this). This is a common problem because you might retrieve +data from the database and serialize them directly to JSON without +noticing the wrong type. If you're getting mysterious errors, double +check that you're inputting numbers and not strings. + +If a null is specified as a point or if one of the coordinates is null +or couldn't be converted to a number, the point is ignored when +drawing. As a special case, a null value for lines is interpreted as a +line segment end, i.e. the points before and after the null value are +not connected. + +Lines and points take two coordinates. For filled lines and bars, you +can specify a third coordinate which is the bottom of the filled +area/bar (defaults to 0). + +The format of a single series object is as follows: + +```js +{ + color: color or number + data: rawdata + label: string + lines: specific lines options + bars: specific bars options + points: specific points options + xaxis: number + yaxis: number + clickable: boolean + hoverable: boolean + shadowSize: number + highlightColor: color or number +} +``` + +You don't have to specify any of them except the data, the rest are +options that will get default values. Typically you'd only specify +label and data, like this: + +```js +{ + label: "y = 3", + data: [[0, 3], [10, 3]] +} +``` + +The label is used for the legend, if you don't specify one, the series +will not show up in the legend. + +If you don't specify color, the series will get a color from the +auto-generated colors. The color is either a CSS color specification +(like "rgb(255, 100, 123)") or an integer that specifies which of +auto-generated colors to select, e.g. 0 will get color no. 0, etc. + +The latter is mostly useful if you let the user add and remove series, +in which case you can hard-code the color index to prevent the colors +from jumping around between the series. + +The "xaxis" and "yaxis" options specify which axis to use. The axes +are numbered from 1 (default), so { yaxis: 2} means that the series +should be plotted against the second y axis. + +"clickable" and "hoverable" can be set to false to disable +interactivity for specific series if interactivity is turned on in +the plot, see below. + +The rest of the options are all documented below as they are the same +as the default options passed in via the options parameter in the plot +commmand. When you specify them for a specific data series, they will +override the default options for the plot for that data series. + +Here's a complete example of a simple data specification: + +```js +[ { label: "Foo", data: [ [10, 1], [17, -14], [30, 5] ] }, + { label: "Bar", data: [ [11, 13], [19, 11], [30, -7] ] } +] +``` + + +## Plot Options ## + +All options are completely optional. They are documented individually +below, to change them you just specify them in an object, e.g. + +```js +var options = { + series: { + lines: { show: true }, + points: { show: true } + } +}; + +$.plot(placeholder, data, options); +``` + + +## Customizing the legend ## + +```js +legend: { + show: boolean + labelFormatter: null or (fn: string, series object -> string) + labelBoxBorderColor: color + noColumns: number + position: "ne" or "nw" or "se" or "sw" + margin: number of pixels or [x margin, y margin] + backgroundColor: null or color + backgroundOpacity: number between 0 and 1 + container: null or jQuery object/DOM element/jQuery expression + sorted: null/false, true, "ascending", "descending", "reverse", or a comparator +} +``` + +The legend is generated as a table with the data series labels and +small label boxes with the color of the series. If you want to format +the labels in some way, e.g. make them to links, you can pass in a +function for "labelFormatter". Here's an example that makes them +clickable: + +```js +labelFormatter: function(label, series) { + // series is the series object for the label + return '' + label + ''; +} +``` + +To prevent a series from showing up in the legend, simply have the function +return null. + +"noColumns" is the number of columns to divide the legend table into. +"position" specifies the overall placement of the legend within the +plot (top-right, top-left, etc.) and margin the distance to the plot +edge (this can be either a number or an array of two numbers like [x, +y]). "backgroundColor" and "backgroundOpacity" specifies the +background. The default is a partly transparent auto-detected +background. + +If you want the legend to appear somewhere else in the DOM, you can +specify "container" as a jQuery object/expression to put the legend +table into. The "position" and "margin" etc. options will then be +ignored. Note that Flot will overwrite the contents of the container. + +Legend entries appear in the same order as their series by default. If "sorted" +is "reverse" then they appear in the opposite order from their series. To sort +them alphabetically, you can specify true, "ascending" or "descending", where +true and "ascending" are equivalent. + +You can also provide your own comparator function that accepts two +objects with "label" and "color" properties, and returns zero if they +are equal, a positive value if the first is greater than the second, +and a negative value if the first is less than the second. + +```js +sorted: function(a, b) { + // sort alphabetically in ascending order + return a.label == b.label ? 0 : ( + a.label > b.label ? 1 : -1 + ) +} +``` + + +## Customizing the axes ## + +```js +xaxis, yaxis: { + show: null or true/false + position: "bottom" or "top" or "left" or "right" + mode: null or "time" ("time" requires jquery.flot.time.js plugin) + timezone: null, "browser" or timezone (only makes sense for mode: "time") + + color: null or color spec + tickColor: null or color spec + font: null or font spec object + + min: null or number + max: null or number + autoscaleMargin: null or number + + transform: null or fn: number -> number + inverseTransform: null or fn: number -> number + + ticks: null or number or ticks array or (fn: axis -> ticks array) + tickSize: number or array + minTickSize: number or array + tickFormatter: (fn: number, object -> string) or string + tickDecimals: null or number + + labelWidth: null or number + labelHeight: null or number + reserveSpace: null or true + + tickLength: null or number + + alignTicksWithAxis: null or number +} +``` + +All axes have the same kind of options. The following describes how to +configure one axis, see below for what to do if you've got more than +one x axis or y axis. + +If you don't set the "show" option (i.e. it is null), visibility is +auto-detected, i.e. the axis will show up if there's data associated +with it. You can override this by setting the "show" option to true or +false. + +The "position" option specifies where the axis is placed, bottom or +top for x axes, left or right for y axes. The "mode" option determines +how the data is interpreted, the default of null means as decimal +numbers. Use "time" for time series data; see the time series data +section. The time plugin (jquery.flot.time.js) is required for time +series support. + +The "color" option determines the color of the line and ticks for the axis, and +defaults to the grid color with transparency. For more fine-grained control you +can also set the color of the ticks separately with "tickColor". + +You can customize the font and color used to draw the axis tick labels with CSS +or directly via the "font" option. When "font" is null - the default - each +tick label is given the 'flot-tick-label' class. For compatibility with Flot +0.7 and earlier the labels are also given the 'tickLabel' class, but this is +deprecated and scheduled to be removed with the release of version 1.0.0. + +To enable more granular control over styles, labels are divided between a set +of text containers, with each holding the labels for one axis. These containers +are given the classes 'flot-[x|y]-axis', and 'flot-[x|y]#-axis', where '#' is +the number of the axis when there are multiple axes. For example, the x-axis +labels for a simple plot with only a single x-axis might look like this: + +```html +
+
January 2013
+ ... +
+``` + +For direct control over label styles you can also provide "font" as an object +with this format: + +```js +{ + size: 11, + lineHeight: 13, + style: "italic", + weight: "bold", + family: "sans-serif", + variant: "small-caps", + color: "#545454" +} +``` + +The size and lineHeight must be expressed in pixels; CSS units such as 'em' +or 'smaller' are not allowed. + +The options "min"/"max" are the precise minimum/maximum value on the +scale. If you don't specify either of them, a value will automatically +be chosen based on the minimum/maximum data values. Note that Flot +always examines all the data values you feed to it, even if a +restriction on another axis may make some of them invisible (this +makes interactive use more stable). + +The "autoscaleMargin" is a bit esoteric: it's the fraction of margin +that the scaling algorithm will add to avoid that the outermost points +ends up on the grid border. Note that this margin is only applied when +a min or max value is not explicitly set. If a margin is specified, +the plot will furthermore extend the axis end-point to the nearest +whole tick. The default value is "null" for the x axes and 0.02 for y +axes which seems appropriate for most cases. + +"transform" and "inverseTransform" are callbacks you can put in to +change the way the data is drawn. You can design a function to +compress or expand certain parts of the axis non-linearly, e.g. +suppress weekends or compress far away points with a logarithm or some +other means. When Flot draws the plot, each value is first put through +the transform function. Here's an example, the x axis can be turned +into a natural logarithm axis with the following code: + +```js +xaxis: { + transform: function (v) { return Math.log(v); }, + inverseTransform: function (v) { return Math.exp(v); } +} +``` + +Similarly, for reversing the y axis so the values appear in inverse +order: + +```js +yaxis: { + transform: function (v) { return -v; }, + inverseTransform: function (v) { return -v; } +} +``` + +Note that for finding extrema, Flot assumes that the transform +function does not reorder values (it should be monotone). + +The inverseTransform is simply the inverse of the transform function +(so v == inverseTransform(transform(v)) for all relevant v). It is +required for converting from canvas coordinates to data coordinates, +e.g. for a mouse interaction where a certain pixel is clicked. If you +don't use any interactive features of Flot, you may not need it. + + +The rest of the options deal with the ticks. + +If you don't specify any ticks, a tick generator algorithm will make +some for you. The algorithm has two passes. It first estimates how +many ticks would be reasonable and uses this number to compute a nice +round tick interval size. Then it generates the ticks. + +You can specify how many ticks the algorithm aims for by setting +"ticks" to a number. The algorithm always tries to generate reasonably +round tick values so even if you ask for three ticks, you might get +five if that fits better with the rounding. If you don't want any +ticks at all, set "ticks" to 0 or an empty array. + +Another option is to skip the rounding part and directly set the tick +interval size with "tickSize". If you set it to 2, you'll get ticks at +2, 4, 6, etc. Alternatively, you can specify that you just don't want +ticks at a size less than a specific tick size with "minTickSize". +Note that for time series, the format is an array like [2, "month"], +see the next section. + +If you want to completely override the tick algorithm, you can specify +an array for "ticks", either like this: + +```js +ticks: [0, 1.2, 2.4] +``` + +Or like this where the labels are also customized: + +```js +ticks: [[0, "zero"], [1.2, "one mark"], [2.4, "two marks"]] +``` + +You can mix the two if you like. + +For extra flexibility you can specify a function as the "ticks" +parameter. The function will be called with an object with the axis +min and max and should return a ticks array. Here's a simplistic tick +generator that spits out intervals of pi, suitable for use on the x +axis for trigonometric functions: + +```js +function piTickGenerator(axis) { + var res = [], i = Math.floor(axis.min / Math.PI); + do { + var v = i * Math.PI; + res.push([v, i + "\u03c0"]); + ++i; + } while (v < axis.max); + return res; +} +``` + +You can control how the ticks look like with "tickDecimals", the +number of decimals to display (default is auto-detected). + +Alternatively, for ultimate control over how ticks are formatted you can +provide a function to "tickFormatter". The function is passed two +parameters, the tick value and an axis object with information, and +should return a string. The default formatter looks like this: + +```js +function formatter(val, axis) { + return val.toFixed(axis.tickDecimals); +} +``` + +The axis object has "min" and "max" with the range of the axis, +"tickDecimals" with the number of decimals to round the value to and +"tickSize" with the size of the interval between ticks as calculated +by the automatic axis scaling algorithm (or specified by you). Here's +an example of a custom formatter: + +```js +function suffixFormatter(val, axis) { + if (val > 1000000) + return (val / 1000000).toFixed(axis.tickDecimals) + " MB"; + else if (val > 1000) + return (val / 1000).toFixed(axis.tickDecimals) + " kB"; + else + return val.toFixed(axis.tickDecimals) + " B"; +} +``` + +"labelWidth" and "labelHeight" specifies a fixed size of the tick +labels in pixels. They're useful in case you need to align several +plots. "reserveSpace" means that even if an axis isn't shown, Flot +should reserve space for it - it is useful in combination with +labelWidth and labelHeight for aligning multi-axis charts. + +"tickLength" is the length of the tick lines in pixels. By default, the +innermost axes will have ticks that extend all across the plot, while +any extra axes use small ticks. A value of null means use the default, +while a number means small ticks of that length - set it to 0 to hide +the lines completely. + +If you set "alignTicksWithAxis" to the number of another axis, e.g. +alignTicksWithAxis: 1, Flot will ensure that the autogenerated ticks +of this axis are aligned with the ticks of the other axis. This may +improve the looks, e.g. if you have one y axis to the left and one to +the right, because the grid lines will then match the ticks in both +ends. The trade-off is that the forced ticks won't necessarily be at +natural places. + + +## Multiple axes ## + +If you need more than one x axis or y axis, you need to specify for +each data series which axis they are to use, as described under the +format of the data series, e.g. { data: [...], yaxis: 2 } specifies +that a series should be plotted against the second y axis. + +To actually configure that axis, you can't use the xaxis/yaxis options +directly - instead there are two arrays in the options: + +```js +xaxes: [] +yaxes: [] +``` + +Here's an example of configuring a single x axis and two y axes (we +can leave options of the first y axis empty as the defaults are fine): + +```js +{ + xaxes: [ { position: "top" } ], + yaxes: [ { }, { position: "right", min: 20 } ] +} +``` + +The arrays get their default values from the xaxis/yaxis settings, so +say you want to have all y axes start at zero, you can simply specify +yaxis: { min: 0 } instead of adding a min parameter to all the axes. + +Generally, the various interfaces in Flot dealing with data points +either accept an xaxis/yaxis parameter to specify which axis number to +use (starting from 1), or lets you specify the coordinate directly as +x2/x3/... or x2axis/x3axis/... instead of "x" or "xaxis". + + +## Time series data ## + +Please note that it is now required to include the time plugin, +jquery.flot.time.js, for time series support. + +Time series are a bit more difficult than scalar data because +calendars don't follow a simple base 10 system. For many cases, Flot +abstracts most of this away, but it can still be a bit difficult to +get the data into Flot. So we'll first discuss the data format. + +The time series support in Flot is based on Javascript timestamps, +i.e. everywhere a time value is expected or handed over, a Javascript +timestamp number is used. This is a number, not a Date object. A +Javascript timestamp is the number of milliseconds since January 1, +1970 00:00:00 UTC. This is almost the same as Unix timestamps, except it's +in milliseconds, so remember to multiply by 1000! + +You can see a timestamp like this + +```js +alert((new Date()).getTime()) +``` + +There are different schools of thought when it comes to display of +timestamps. Many will want the timestamps to be displayed according to +a certain time zone, usually the time zone in which the data has been +produced. Some want the localized experience, where the timestamps are +displayed according to the local time of the visitor. Flot supports +both. Optionally you can include a third-party library to get +additional timezone support. + +Default behavior is that Flot always displays timestamps according to +UTC. The reason being that the core Javascript Date object does not +support other fixed time zones. Often your data is at another time +zone, so it may take a little bit of tweaking to work around this +limitation. + +The easiest way to think about it is to pretend that the data +production time zone is UTC, even if it isn't. So if you have a +datapoint at 2002-02-20 08:00, you can generate a timestamp for eight +o'clock UTC even if it really happened eight o'clock UTC+0200. + +In PHP you can get an appropriate timestamp with: + +```php +strtotime("2002-02-20 UTC") * 1000 +``` + +In Python you can get it with something like: + +```python +calendar.timegm(datetime_object.timetuple()) * 1000 +``` +In Ruby you can get it using the `#to_i` method on the +[`Time`](http://apidock.com/ruby/Time/to_i) object. If you're using the +`active_support` gem (default for Ruby on Rails applications) `#to_i` is also +available on the `DateTime` and `ActiveSupport::TimeWithZone` objects. You +simply need to multiply the result by 1000: + +```ruby +Time.now.to_i * 1000 # => 1383582043000 +# ActiveSupport examples: +DateTime.now.to_i * 1000 # => 1383582043000 +ActiveSupport::TimeZone.new('Asia/Shanghai').now.to_i * 1000 +# => 1383582043000 +``` + +In .NET you can get it with something like: + +```aspx +public static int GetJavascriptTimestamp(System.DateTime input) +{ + System.TimeSpan span = new System.TimeSpan(System.DateTime.Parse("1/1/1970").Ticks); + System.DateTime time = input.Subtract(span); + return (long)(time.Ticks / 10000); +} +``` + +Javascript also has some support for parsing date strings, so it is +possible to generate the timestamps manually client-side. + +If you've already got the real UTC timestamp, it's too late to use the +pretend trick described above. But you can fix up the timestamps by +adding the time zone offset, e.g. for UTC+0200 you would add 2 hours +to the UTC timestamp you got. Then it'll look right on the plot. Most +programming environments have some means of getting the timezone +offset for a specific date (note that you need to get the offset for +each individual timestamp to account for daylight savings). + +The alternative with core Javascript is to interpret the timestamps +according to the time zone that the visitor is in, which means that +the ticks will shift with the time zone and daylight savings of each +visitor. This behavior is enabled by setting the axis option +"timezone" to the value "browser". + +If you need more time zone functionality than this, there is still +another option. If you include the "timezone-js" library + in the page and set axis.timezone +to a value recognized by said library, Flot will use timezone-js to +interpret the timestamps according to that time zone. + +Once you've gotten the timestamps into the data and specified "time" +as the axis mode, Flot will automatically generate relevant ticks and +format them. As always, you can tweak the ticks via the "ticks" option +- just remember that the values should be timestamps (numbers), not +Date objects. + +Tick generation and formatting can also be controlled separately +through the following axis options: + +```js +minTickSize: array +timeformat: null or format string +monthNames: null or array of size 12 of strings +dayNames: null or array of size 7 of strings +twelveHourClock: boolean +``` + +Here "timeformat" is a format string to use. You might use it like +this: + +```js +xaxis: { + mode: "time", + timeformat: "%Y/%m/%d" +} +``` + +This will result in tick labels like "2000/12/24". A subset of the +standard strftime specifiers are supported (plus the nonstandard %q): + +```js +%a: weekday name (customizable) +%b: month name (customizable) +%d: day of month, zero-padded (01-31) +%e: day of month, space-padded ( 1-31) +%H: hours, 24-hour time, zero-padded (00-23) +%I: hours, 12-hour time, zero-padded (01-12) +%m: month, zero-padded (01-12) +%M: minutes, zero-padded (00-59) +%q: quarter (1-4) +%S: seconds, zero-padded (00-59) +%y: year (two digits) +%Y: year (four digits) +%p: am/pm +%P: AM/PM (uppercase version of %p) +%w: weekday as number (0-6, 0 being Sunday) +``` + +Flot 0.8 switched from %h to the standard %H hours specifier. The %h specifier +is still available, for backwards-compatibility, but is deprecated and +scheduled to be removed permanently with the release of version 1.0. + +You can customize the month names with the "monthNames" option. For +instance, for Danish you might specify: + +```js +monthNames: ["jan", "feb", "mar", "apr", "maj", "jun", "jul", "aug", "sep", "okt", "nov", "dec"] +``` + +Similarly you can customize the weekday names with the "dayNames" +option. An example in French: + +```js +dayNames: ["dim", "lun", "mar", "mer", "jeu", "ven", "sam"] +``` + +If you set "twelveHourClock" to true, the autogenerated timestamps +will use 12 hour AM/PM timestamps instead of 24 hour. This only +applies if you have not set "timeformat". Use the "%I" and "%p" or +"%P" options if you want to build your own format string with 12-hour +times. + +If the Date object has a strftime property (and it is a function), it +will be used instead of the built-in formatter. Thus you can include +a strftime library such as http://hacks.bluesmoon.info/strftime/ for +more powerful date/time formatting. + +If everything else fails, you can control the formatting by specifying +a custom tick formatter function as usual. Here's a simple example +which will format December 24 as 24/12: + +```js +tickFormatter: function (val, axis) { + var d = new Date(val); + return d.getUTCDate() + "/" + (d.getUTCMonth() + 1); +} +``` + +Note that for the time mode "tickSize" and "minTickSize" are a bit +special in that they are arrays on the form "[value, unit]" where unit +is one of "second", "minute", "hour", "day", "month" and "year". So +you can specify + +```js +minTickSize: [1, "month"] +``` + +to get a tick interval size of at least 1 month and correspondingly, +if axis.tickSize is [2, "day"] in the tick formatter, the ticks have +been produced with two days in-between. + + +## Customizing the data series ## + +```js +series: { + lines, points, bars: { + show: boolean + lineWidth: number + fill: boolean or number + fillColor: null or color/gradient + } + + lines, bars: { + zero: boolean + } + + points: { + radius: number + symbol: "circle" or function + } + + bars: { + barWidth: number + align: "left", "right" or "center" + horizontal: boolean + } + + lines: { + steps: boolean + } + + shadowSize: number + highlightColor: color or number +} + +colors: [ color1, color2, ... ] +``` + +The options inside "series: {}" are copied to each of the series. So +you can specify that all series should have bars by putting it in the +global options, or override it for individual series by specifying +bars in a particular the series object in the array of data. + +The most important options are "lines", "points" and "bars" that +specify whether and how lines, points and bars should be shown for +each data series. In case you don't specify anything at all, Flot will +default to showing lines (you can turn this off with +lines: { show: false }). You can specify the various types +independently of each other, and Flot will happily draw each of them +in turn (this is probably only useful for lines and points), e.g. + +```js +var options = { + series: { + lines: { show: true, fill: true, fillColor: "rgba(255, 255, 255, 0.8)" }, + points: { show: true, fill: false } + } +}; +``` + +"lineWidth" is the thickness of the line or outline in pixels. You can +set it to 0 to prevent a line or outline from being drawn; this will +also hide the shadow. + +"fill" is whether the shape should be filled. For lines, this produces +area graphs. You can use "fillColor" to specify the color of the fill. +If "fillColor" evaluates to false (default for everything except +points which are filled with white), the fill color is auto-set to the +color of the data series. You can adjust the opacity of the fill by +setting fill to a number between 0 (fully transparent) and 1 (fully +opaque). + +For bars, fillColor can be a gradient, see the gradient documentation +below. "barWidth" is the width of the bars in units of the x axis (or +the y axis if "horizontal" is true), contrary to most other measures +that are specified in pixels. For instance, for time series the unit +is milliseconds so 24 * 60 * 60 * 1000 produces bars with the width of +a day. "align" specifies whether a bar should be left-aligned +(default), right-aligned or centered on top of the value it represents. +When "horizontal" is on, the bars are drawn horizontally, i.e. from the +y axis instead of the x axis; note that the bar end points are still +defined in the same way so you'll probably want to swap the +coordinates if you've been plotting vertical bars first. + +Area and bar charts normally start from zero, regardless of the data's range. +This is because they convey information through size, and starting from a +different value would distort their meaning. In cases where the fill is purely +for decorative purposes, however, "zero" allows you to override this behavior. +It defaults to true for filled lines and bars; setting it to false tells the +series to use the same automatic scaling as an un-filled line. + +For lines, "steps" specifies whether two adjacent data points are +connected with a straight (possibly diagonal) line or with first a +horizontal and then a vertical line. Note that this transforms the +data by adding extra points. + +For points, you can specify the radius and the symbol. The only +built-in symbol type is circles, for other types you can use a plugin +or define them yourself by specifying a callback: + +```js +function cross(ctx, x, y, radius, shadow) { + var size = radius * Math.sqrt(Math.PI) / 2; + ctx.moveTo(x - size, y - size); + ctx.lineTo(x + size, y + size); + ctx.moveTo(x - size, y + size); + ctx.lineTo(x + size, y - size); +} +``` + +The parameters are the drawing context, x and y coordinates of the +center of the point, a radius which corresponds to what the circle +would have used and whether the call is to draw a shadow (due to +limited canvas support, shadows are currently faked through extra +draws). It's good practice to ensure that the area covered by the +symbol is the same as for the circle with the given radius, this +ensures that all symbols have approximately the same visual weight. + +"shadowSize" is the default size of shadows in pixels. Set it to 0 to +remove shadows. + +"highlightColor" is the default color of the translucent overlay used +to highlight the series when the mouse hovers over it. + +The "colors" array specifies a default color theme to get colors for +the data series from. You can specify as many colors as you like, like +this: + +```js +colors: ["#d18b2c", "#dba255", "#919733"] +``` + +If there are more data series than colors, Flot will try to generate +extra colors by lightening and darkening colors in the theme. + + +## Customizing the grid ## + +```js +grid: { + show: boolean + aboveData: boolean + color: color + backgroundColor: color/gradient or null + margin: number or margin object + labelMargin: number + axisMargin: number + markings: array of markings or (fn: axes -> array of markings) + borderWidth: number or object with "top", "right", "bottom" and "left" properties with different widths + borderColor: color or null or object with "top", "right", "bottom" and "left" properties with different colors + minBorderMargin: number or null + clickable: boolean + hoverable: boolean + autoHighlight: boolean + mouseActiveRadius: number +} + +interaction: { + redrawOverlayInterval: number or -1 +} +``` + +The grid is the thing with the axes and a number of ticks. Many of the +things in the grid are configured under the individual axes, but not +all. "color" is the color of the grid itself whereas "backgroundColor" +specifies the background color inside the grid area, here null means +that the background is transparent. You can also set a gradient, see +the gradient documentation below. + +You can turn off the whole grid including tick labels by setting +"show" to false. "aboveData" determines whether the grid is drawn +above the data or below (below is default). + +"margin" is the space in pixels between the canvas edge and the grid, +which can be either a number or an object with individual margins for +each side, in the form: + +```js +margin: { + top: top margin in pixels + left: left margin in pixels + bottom: bottom margin in pixels + right: right margin in pixels +} +``` + +"labelMargin" is the space in pixels between tick labels and axis +line, and "axisMargin" is the space in pixels between axes when there +are two next to each other. + +"borderWidth" is the width of the border around the plot. Set it to 0 +to disable the border. Set it to an object with "top", "right", +"bottom" and "left" properties to use different widths. You can +also set "borderColor" if you want the border to have a different color +than the grid lines. Set it to an object with "top", "right", "bottom" +and "left" properties to use different colors. "minBorderMargin" controls +the default minimum margin around the border - it's used to make sure +that points aren't accidentally clipped by the canvas edge so by default +the value is computed from the point radius. + +"markings" is used to draw simple lines and rectangular areas in the +background of the plot. You can either specify an array of ranges on +the form { xaxis: { from, to }, yaxis: { from, to } } (with multiple +axes, you can specify coordinates for other axes instead, e.g. as +x2axis/x3axis/...) or with a function that returns such an array given +the axes for the plot in an object as the first parameter. + +You can set the color of markings by specifying "color" in the ranges +object. Here's an example array: + +```js +markings: [ { xaxis: { from: 0, to: 2 }, yaxis: { from: 10, to: 10 }, color: "#bb0000" }, ... ] +``` + +If you leave out one of the values, that value is assumed to go to the +border of the plot. So for example if you only specify { xaxis: { +from: 0, to: 2 } } it means an area that extends from the top to the +bottom of the plot in the x range 0-2. + +A line is drawn if from and to are the same, e.g. + +```js +markings: [ { yaxis: { from: 1, to: 1 } }, ... ] +``` + +would draw a line parallel to the x axis at y = 1. You can control the +line width with "lineWidth" in the range object. + +An example function that makes vertical stripes might look like this: + +```js +markings: function (axes) { + var markings = []; + for (var x = Math.floor(axes.xaxis.min); x < axes.xaxis.max; x += 2) + markings.push({ xaxis: { from: x, to: x + 1 } }); + return markings; +} +``` + +If you set "clickable" to true, the plot will listen for click events +on the plot area and fire a "plotclick" event on the placeholder with +a position and a nearby data item object as parameters. The coordinates +are available both in the unit of the axes (not in pixels) and in +global screen coordinates. + +Likewise, if you set "hoverable" to true, the plot will listen for +mouse move events on the plot area and fire a "plothover" event with +the same parameters as the "plotclick" event. If "autoHighlight" is +true (the default), nearby data items are highlighted automatically. +If needed, you can disable highlighting and control it yourself with +the highlight/unhighlight plot methods described elsewhere. + +You can use "plotclick" and "plothover" events like this: + +```js +$.plot($("#placeholder"), [ d ], { grid: { clickable: true } }); + +$("#placeholder").bind("plotclick", function (event, pos, item) { + alert("You clicked at " + pos.x + ", " + pos.y); + // axis coordinates for other axes, if present, are in pos.x2, pos.x3, ... + // if you need global screen coordinates, they are pos.pageX, pos.pageY + + if (item) { + highlight(item.series, item.datapoint); + alert("You clicked a point!"); + } +}); +``` + +The item object in this example is either null or a nearby object on the form: + +```js +item: { + datapoint: the point, e.g. [0, 2] + dataIndex: the index of the point in the data array + series: the series object + seriesIndex: the index of the series + pageX, pageY: the global screen coordinates of the point +} +``` + +For instance, if you have specified the data like this + +```js +$.plot($("#placeholder"), [ { label: "Foo", data: [[0, 10], [7, 3]] } ], ...); +``` + +and the mouse is near the point (7, 3), "datapoint" is [7, 3], +"dataIndex" will be 1, "series" is a normalized series object with +among other things the "Foo" label in series.label and the color in +series.color, and "seriesIndex" is 0. Note that plugins and options +that transform the data can shift the indexes from what you specified +in the original data array. + +If you use the above events to update some other information and want +to clear out that info in case the mouse goes away, you'll probably +also need to listen to "mouseout" events on the placeholder div. + +"mouseActiveRadius" specifies how far the mouse can be from an item +and still activate it. If there are two or more points within this +radius, Flot chooses the closest item. For bars, the top-most bar +(from the latest specified data series) is chosen. + +If you want to disable interactivity for a specific data series, you +can set "hoverable" and "clickable" to false in the options for that +series, like this: + +```js +{ data: [...], label: "Foo", clickable: false } +``` + +"redrawOverlayInterval" specifies the maximum time to delay a redraw +of interactive things (this works as a rate limiting device). The +default is capped to 60 frames per second. You can set it to -1 to +disable the rate limiting. + + +## Specifying gradients ## + +A gradient is specified like this: + +```js +{ colors: [ color1, color2, ... ] } +``` + +For instance, you might specify a background on the grid going from +black to gray like this: + +```js +grid: { + backgroundColor: { colors: ["#000", "#999"] } +} +``` + +For the series you can specify the gradient as an object that +specifies the scaling of the brightness and the opacity of the series +color, e.g. + +```js +{ colors: [{ opacity: 0.8 }, { brightness: 0.6, opacity: 0.8 } ] } +``` + +where the first color simply has its alpha scaled, whereas the second +is also darkened. For instance, for bars the following makes the bars +gradually disappear, without outline: + +```js +bars: { + show: true, + lineWidth: 0, + fill: true, + fillColor: { colors: [ { opacity: 0.8 }, { opacity: 0.1 } ] } +} +``` + +Flot currently only supports vertical gradients drawn from top to +bottom because that's what works with IE. + + +## Plot Methods ## + +The Plot object returned from the plot function has some methods you +can call: + + - highlight(series, datapoint) + + Highlight a specific datapoint in the data series. You can either + specify the actual objects, e.g. if you got them from a + "plotclick" event, or you can specify the indices, e.g. + highlight(1, 3) to highlight the fourth point in the second series + (remember, zero-based indexing). + + - unhighlight(series, datapoint) or unhighlight() + + Remove the highlighting of the point, same parameters as + highlight. + + If you call unhighlight with no parameters, e.g. as + plot.unhighlight(), all current highlights are removed. + + - setData(data) + + You can use this to reset the data used. Note that axis scaling, + ticks, legend etc. will not be recomputed (use setupGrid() to do + that). You'll probably want to call draw() afterwards. + + You can use this function to speed up redrawing a small plot if + you know that the axes won't change. Put in the new data with + setData(newdata), call draw(), and you're good to go. Note that + for large datasets, almost all the time is consumed in draw() + plotting the data so in this case don't bother. + + - setupGrid() + + Recalculate and set axis scaling, ticks, legend etc. + + Note that because of the drawing model of the canvas, this + function will immediately redraw (actually reinsert in the DOM) + the labels and the legend, but not the actual tick lines because + they're drawn on the canvas. You need to call draw() to get the + canvas redrawn. + + - draw() + + Redraws the plot canvas. + + - triggerRedrawOverlay() + + Schedules an update of an overlay canvas used for drawing + interactive things like a selection and point highlights. This + is mostly useful for writing plugins. The redraw doesn't happen + immediately, instead a timer is set to catch multiple successive + redraws (e.g. from a mousemove). You can get to the overlay by + setting up a drawOverlay hook. + + - width()/height() + + Gets the width and height of the plotting area inside the grid. + This is smaller than the canvas or placeholder dimensions as some + extra space is needed (e.g. for labels). + + - offset() + + Returns the offset of the plotting area inside the grid relative + to the document, useful for instance for calculating mouse + positions (event.pageX/Y minus this offset is the pixel position + inside the plot). + + - pointOffset({ x: xpos, y: ypos }) + + Returns the calculated offset of the data point at (x, y) in data + space within the placeholder div. If you are working with multiple + axes, you can specify the x and y axis references, e.g. + + ```js + o = pointOffset({ x: xpos, y: ypos, xaxis: 2, yaxis: 3 }) + // o.left and o.top now contains the offset within the div + ```` + + - resize() + + Tells Flot to resize the drawing canvas to the size of the + placeholder. You need to run setupGrid() and draw() afterwards as + canvas resizing is a destructive operation. This is used + internally by the resize plugin. + + - shutdown() + + Cleans up any event handlers Flot has currently registered. This + is used internally. + +There are also some members that let you peek inside the internal +workings of Flot which is useful in some cases. Note that if you change +something in the objects returned, you're changing the objects used by +Flot to keep track of its state, so be careful. + + - getData() + + Returns an array of the data series currently used in normalized + form with missing settings filled in according to the global + options. So for instance to find out what color Flot has assigned + to the data series, you could do this: + + ```js + var series = plot.getData(); + for (var i = 0; i < series.length; ++i) + alert(series[i].color); + ``` + + A notable other interesting field besides color is datapoints + which has a field "points" with the normalized data points in a + flat array (the field "pointsize" is the increment in the flat + array to get to the next point so for a dataset consisting only of + (x,y) pairs it would be 2). + + - getAxes() + + Gets an object with the axes. The axes are returned as the + attributes of the object, so for instance getAxes().xaxis is the + x axis. + + Various things are stuffed inside an axis object, e.g. you could + use getAxes().xaxis.ticks to find out what the ticks are for the + xaxis. Two other useful attributes are p2c and c2p, functions for + transforming from data point space to the canvas plot space and + back. Both returns values that are offset with the plot offset. + Check the Flot source code for the complete set of attributes (or + output an axis with console.log() and inspect it). + + With multiple axes, the extra axes are returned as x2axis, x3axis, + etc., e.g. getAxes().y2axis is the second y axis. You can check + y2axis.used to see whether the axis is associated with any data + points and y2axis.show to see if it is currently shown. + + - getPlaceholder() + + Returns placeholder that the plot was put into. This can be useful + for plugins for adding DOM elements or firing events. + + - getCanvas() + + Returns the canvas used for drawing in case you need to hack on it + yourself. You'll probably need to get the plot offset too. + + - getPlotOffset() + + Gets the offset that the grid has within the canvas as an object + with distances from the canvas edges as "left", "right", "top", + "bottom". I.e., if you draw a circle on the canvas with the center + placed at (left, top), its center will be at the top-most, left + corner of the grid. + + - getOptions() + + Gets the options for the plot, normalized, with default values + filled in. You get a reference to actual values used by Flot, so + if you modify the values in here, Flot will use the new values. + If you change something, you probably have to call draw() or + setupGrid() or triggerRedrawOverlay() to see the change. + + +## Hooks ## + +In addition to the public methods, the Plot object also has some hooks +that can be used to modify the plotting process. You can install a +callback function at various points in the process, the function then +gets access to the internal data structures in Flot. + +Here's an overview of the phases Flot goes through: + + 1. Plugin initialization, parsing options + + 2. Constructing the canvases used for drawing + + 3. Set data: parsing data specification, calculating colors, + copying raw data points into internal format, + normalizing them, finding max/min for axis auto-scaling + + 4. Grid setup: calculating axis spacing, ticks, inserting tick + labels, the legend + + 5. Draw: drawing the grid, drawing each of the series in turn + + 6. Setting up event handling for interactive features + + 7. Responding to events, if any + + 8. Shutdown: this mostly happens in case a plot is overwritten + +Each hook is simply a function which is put in the appropriate array. +You can add them through the "hooks" option, and they are also available +after the plot is constructed as the "hooks" attribute on the returned +plot object, e.g. + +```js + // define a simple draw hook + function hellohook(plot, canvascontext) { alert("hello!"); }; + + // pass it in, in an array since we might want to specify several + var plot = $.plot(placeholder, data, { hooks: { draw: [hellohook] } }); + + // we can now find it again in plot.hooks.draw[0] unless a plugin + // has added other hooks +``` + +The available hooks are described below. All hook callbacks get the +plot object as first parameter. You can find some examples of defined +hooks in the plugins bundled with Flot. + + - processOptions [phase 1] + + ```function(plot, options)``` + + Called after Flot has parsed and merged options. Useful in the + instance where customizations beyond simple merging of default + values is needed. A plugin might use it to detect that it has been + enabled and then turn on or off other options. + + + - processRawData [phase 3] + + ```function(plot, series, data, datapoints)``` + + Called before Flot copies and normalizes the raw data for the given + series. If the function fills in datapoints.points with normalized + points and sets datapoints.pointsize to the size of the points, + Flot will skip the copying/normalization step for this series. + + In any case, you might be interested in setting datapoints.format, + an array of objects for specifying how a point is normalized and + how it interferes with axis scaling. It accepts the following options: + + ```js + { + x, y: boolean, + number: boolean, + required: boolean, + defaultValue: value, + autoscale: boolean + } + ``` + + "x" and "y" specify whether the value is plotted against the x or y axis, + and is currently used only to calculate axis min-max ranges. The default + format array, for example, looks like this: + + ```js + [ + { x: true, number: true, required: true }, + { y: true, number: true, required: true } + ] + ``` + + This indicates that a point, i.e. [0, 25], consists of two values, with the + first being plotted on the x axis and the second on the y axis. + + If "number" is true, then the value must be numeric, and is set to null if + it cannot be converted to a number. + + "defaultValue" provides a fallback in case the original value is null. This + is for instance handy for bars, where one can omit the third coordinate + (the bottom of the bar), which then defaults to zero. + + If "required" is true, then the value must exist (be non-null) for the + point as a whole to be valid. If no value is provided, then the entire + point is cleared out with nulls, turning it into a gap in the series. + + "autoscale" determines whether the value is considered when calculating an + automatic min-max range for the axes that the value is plotted against. + + - processDatapoints [phase 3] + + ```function(plot, series, datapoints)``` + + Called after normalization of the given series but before finding + min/max of the data points. This hook is useful for implementing data + transformations. "datapoints" contains the normalized data points in + a flat array as datapoints.points with the size of a single point + given in datapoints.pointsize. Here's a simple transform that + multiplies all y coordinates by 2: + + ```js + function multiply(plot, series, datapoints) { + var points = datapoints.points, ps = datapoints.pointsize; + for (var i = 0; i < points.length; i += ps) + points[i + 1] *= 2; + } + ``` + + Note that you must leave datapoints in a good condition as Flot + doesn't check it or do any normalization on it afterwards. + + - processOffset [phase 4] + + ```function(plot, offset)``` + + Called after Flot has initialized the plot's offset, but before it + draws any axes or plot elements. This hook is useful for customizing + the margins between the grid and the edge of the canvas. "offset" is + an object with attributes "top", "bottom", "left" and "right", + corresponding to the margins on the four sides of the plot. + + - drawBackground [phase 5] + + ```function(plot, canvascontext)``` + + Called before all other drawing operations. Used to draw backgrounds + or other custom elements before the plot or axes have been drawn. + + - drawSeries [phase 5] + + ```function(plot, canvascontext, series)``` + + Hook for custom drawing of a single series. Called just before the + standard drawing routine has been called in the loop that draws + each series. + + - draw [phase 5] + + ```function(plot, canvascontext)``` + + Hook for drawing on the canvas. Called after the grid is drawn + (unless it's disabled or grid.aboveData is set) and the series have + been plotted (in case any points, lines or bars have been turned + on). For examples of how to draw things, look at the source code. + + - bindEvents [phase 6] + + ```function(plot, eventHolder)``` + + Called after Flot has setup its event handlers. Should set any + necessary event handlers on eventHolder, a jQuery object with the + canvas, e.g. + + ```js + function (plot, eventHolder) { + eventHolder.mousedown(function (e) { + alert("You pressed the mouse at " + e.pageX + " " + e.pageY); + }); + } + ``` + + Interesting events include click, mousemove, mouseup/down. You can + use all jQuery events. Usually, the event handlers will update the + state by drawing something (add a drawOverlay hook and call + triggerRedrawOverlay) or firing an externally visible event for + user code. See the crosshair plugin for an example. + + Currently, eventHolder actually contains both the static canvas + used for the plot itself and the overlay canvas used for + interactive features because some versions of IE get the stacking + order wrong. The hook only gets one event, though (either for the + overlay or for the static canvas). + + Note that custom plot events generated by Flot are not generated on + eventHolder, but on the div placeholder supplied as the first + argument to the plot call. You can get that with + plot.getPlaceholder() - that's probably also the one you should use + if you need to fire a custom event. + + - drawOverlay [phase 7] + + ```function (plot, canvascontext)``` + + The drawOverlay hook is used for interactive things that need a + canvas to draw on. The model currently used by Flot works the way + that an extra overlay canvas is positioned on top of the static + canvas. This overlay is cleared and then completely redrawn + whenever something interesting happens. This hook is called when + the overlay canvas is to be redrawn. + + "canvascontext" is the 2D context of the overlay canvas. You can + use this to draw things. You'll most likely need some of the + metrics computed by Flot, e.g. plot.width()/plot.height(). See the + crosshair plugin for an example. + + - shutdown [phase 8] + + ```function (plot, eventHolder)``` + + Run when plot.shutdown() is called, which usually only happens in + case a plot is overwritten by a new plot. If you're writing a + plugin that adds extra DOM elements or event handlers, you should + add a callback to clean up after you. Take a look at the section in + the [PLUGINS](PLUGINS.md) document for more info. + + +## Plugins ## + +Plugins extend the functionality of Flot. To use a plugin, simply +include its Javascript file after Flot in the HTML page. + +If you're worried about download size/latency, you can concatenate all +the plugins you use, and Flot itself for that matter, into one big file +(make sure you get the order right), then optionally run it through a +Javascript minifier such as YUI Compressor. + +Here's a brief explanation of how the plugin plumbings work: + +Each plugin registers itself in the global array $.plot.plugins. When +you make a new plot object with $.plot, Flot goes through this array +calling the "init" function of each plugin and merging default options +from the "option" attribute of the plugin. The init function gets a +reference to the plot object created and uses this to register hooks +and add new public methods if needed. + +See the [PLUGINS](PLUGINS.md) document for details on how to write a plugin. As the +above description hints, it's actually pretty easy. + + +## Version number ## + +The version number of Flot is available in ```$.plot.version```. diff --git a/helpdesk/static/helpdesk/vendor/flot/FAQ.md b/helpdesk/static/helpdesk/vendor/flot/FAQ.md new file mode 100644 index 00000000..9131e043 --- /dev/null +++ b/helpdesk/static/helpdesk/vendor/flot/FAQ.md @@ -0,0 +1,75 @@ +## Frequently asked questions ## + +#### How much data can Flot cope with? #### + +Flot will happily draw everything you send to it so the answer +depends on the browser. The excanvas emulation used for IE (built with +VML) makes IE by far the slowest browser so be sure to test with that +if IE users are in your target group (for large plots in IE, you can +also check out Flashcanvas which may be faster). + +1000 points is not a problem, but as soon as you start having more +points than the pixel width, you should probably start thinking about +downsampling/aggregation as this is near the resolution limit of the +chart anyway. If you downsample server-side, you also save bandwidth. + + +#### Flot isn't working when I'm using JSON data as source! #### + +Actually, Flot loves JSON data, you just got the format wrong. +Double check that you're not inputting strings instead of numbers, +like [["0", "-2.13"], ["5", "4.3"]]. This is most common mistake, and +the error might not show up immediately because Javascript can do some +conversion automatically. + + +#### Can I export the graph? #### + +You can grab the image rendered by the canvas element used by Flot +as a PNG or JPEG (remember to set a background). Note that it won't +include anything not drawn in the canvas (such as the legend). And it +doesn't work with excanvas which uses VML, but you could try +Flashcanvas. + + +#### The bars are all tiny in time mode? #### + +It's not really possible to determine the bar width automatically. +So you have to set the width with the barWidth option which is NOT in +pixels, but in the units of the x axis (or the y axis for horizontal +bars). For time mode that's milliseconds so the default value of 1 +makes the bars 1 millisecond wide. + + +#### Can I use Flot with libraries like Mootools or Prototype? #### + +Yes, Flot supports it out of the box and it's easy! Just use jQuery +instead of $, e.g. call jQuery.plot instead of $.plot and use +jQuery(something) instead of $(something). As a convenience, you can +put in a DOM element for the graph placeholder where the examples and +the API documentation are using jQuery objects. + +Depending on how you include jQuery, you may have to add one line of +code to prevent jQuery from overwriting functions from the other +libraries, see the documentation in jQuery ("Using jQuery with other +libraries") for details. + + +#### Flot doesn't work with [insert name of Javascript UI framework]! #### + +Flot is using standard HTML to make charts. If this is not working, +it's probably because the framework you're using is doing something +weird with the DOM or with the CSS that is interfering with Flot. + +A common problem is that there's display:none on a container until the +user does something. Many tab widgets work this way, and there's +nothing wrong with it - you just can't call Flot inside a display:none +container as explained in the README so you need to hold off the Flot +call until the container is actually displayed (or use +visibility:hidden instead of display:none or move the container +off-screen). + +If you find there's a specific thing we can do to Flot to help, feel +free to submit a bug report. Otherwise, you're welcome to ask for help +on the forum/mailing list, but please don't submit a bug report to +Flot. diff --git a/helpdesk/static/helpdesk/vendor/flot/LICENSE.txt b/helpdesk/static/helpdesk/vendor/flot/LICENSE.txt new file mode 100644 index 00000000..719da064 --- /dev/null +++ b/helpdesk/static/helpdesk/vendor/flot/LICENSE.txt @@ -0,0 +1,22 @@ +Copyright (c) 2007-2014 IOLA and Ole Laursen + +Permission is hereby granted, free of charge, to any person +obtaining a copy of this software and associated documentation +files (the "Software"), to deal in the Software without +restriction, including without limitation the rights to use, +copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the +Software is furnished to do so, subject to the following +conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES +OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +NONINFRINGEMENT.

It has a single option that control whether it is enabled and +how much info to output: + +```js +(function ($) { + function init(plot) { + var debugLevel = 1; + + function checkDebugEnabled(plot, options) { + if (options.debug) { + debugLevel = options.debug; + plot.hooks.processDatapoints.push(alertSeries); + } + } + + function alertSeries(plot, series, datapoints) { + var msg = "series " + series.label; + if (debugLevel > 1) { + msg += " with " + series.data.length + " points"; + alert(msg); + } + } + + plot.hooks.processOptions.push(checkDebugEnabled); + } + + var options = { debug: 0 }; + + $.plot.plugins.push({ + init: init, + options: options, + name: "simpledebug", + version: "0.1" + }); +})(jQuery); +``` + +We also define "name" and "version". It's not used by Flot, but might +be helpful for other plugins in resolving dependencies. + +Put the above in a file named "jquery.flot.debug.js", include it in an +HTML page and then it can be used with: + +```js + $.plot($("#placeholder"), [...], { debug: 2 }); +``` + +This simple plugin illustrates a couple of points: + + - It uses the anonymous function trick to avoid name pollution. + - It can be enabled/disabled through an option. + - Variables in the init function can be used to store plot-specific + state between the hooks. + +The two last points are important because there may be multiple plots +on the same page, and you'd want to make sure they are not mixed up. + + +## Shutting down a plugin ## + +Each plot object has a shutdown hook which is run when plot.shutdown() +is called. This usually mostly happens in case another plot is made on +top of an existing one. + +The purpose of the hook is to give you a chance to unbind any event +handlers you've registered and remove any extra DOM things you've +inserted. + +The problem with event handlers is that you can have registered a +handler which is run in some point in the future, e.g. with +setTimeout(). Meanwhile, the plot may have been shutdown and removed, +but because your event handler is still referencing it, it can't be +garbage collected yet, and worse, if your handler eventually runs, it +may overwrite stuff on a completely different plot. + + +## Some hints on the options ## + +Plugins should always support appropriate options to enable/disable +them because the plugin user may have several plots on the same page +where only one should use the plugin. In most cases it's probably a +good idea if the plugin is turned off rather than on per default, just +like most of the powerful features in Flot. + +If the plugin needs options that are specific to each series, like the +points or lines options in core Flot, you can put them in "series" in +the options object, e.g. + +```js +var options = { + series: { + downsample: { + algorithm: null, + maxpoints: 1000 + } + } +} +``` + +Then they will be copied by Flot into each series, providing default +values in case none are specified. + +Think hard and long about naming the options. These names are going to +be public API, and code is going to depend on them if the plugin is +successful. diff --git a/helpdesk/static/helpdesk/vendor/flot/README.md b/helpdesk/static/helpdesk/vendor/flot/README.md new file mode 100644 index 00000000..a8f70640 --- /dev/null +++ b/helpdesk/static/helpdesk/vendor/flot/README.md @@ -0,0 +1,110 @@ +# Flot [![Build status](https://travis-ci.org/flot/flot.png)](https://travis-ci.org/flot/flot) + +## About ## + +Flot is a Javascript plotting library for jQuery. +Read more at the website: + +Take a look at the the examples in examples/index.html; they should give a good +impression of what Flot can do, and the source code of the examples is probably +the fastest way to learn how to use Flot. + + +## Installation ## + +Just include the Javascript file after you've included jQuery. + +Generally, all browsers that support the HTML5 canvas tag are +supported. + +For support for Internet Explorer < 9, you can use [Excanvas] +[excanvas], a canvas emulator; this is used in the examples bundled +with Flot. You just include the excanvas script like this: + +```html + +``` + +If it's not working on your development IE 6.0, check that it has +support for VML which Excanvas is relying on. It appears that some +stripped down versions used for test environments on virtual machines +lack the VML support. + +You can also try using [Flashcanvas][flashcanvas], which uses Flash to +do the emulation. Although Flash can be a bit slower to load than VML, +if you've got a lot of points, the Flash version can be much faster +overall. Flot contains some wrapper code for activating Excanvas which +Flashcanvas is compatible with. + +You need at least jQuery 1.2.6, but try at least 1.3.2 for interactive +charts because of performance improvements in event handling. + + +## Basic usage ## + +Create a placeholder div to put the graph in: + +```html +
+``` + +You need to set the width and height of this div, otherwise the plot +library doesn't know how to scale the graph. You can do it inline like +this: + +```html +
+``` + +You can also do it with an external stylesheet. Make sure that the +placeholder isn't within something with a display:none CSS property - +in that case, Flot has trouble measuring label dimensions which +results in garbled looks and might have trouble measuring the +placeholder dimensions which is fatal (it'll throw an exception). + +Then when the div is ready in the DOM, which is usually on document +ready, run the plot function: + +```js +$.plot($("#placeholder"), data, options); +``` + +Here, data is an array of data series and options is an object with +settings if you want to customize the plot. Take a look at the +examples for some ideas of what to put in or look at the +[API reference](API.md). Here's a quick example that'll draw a line +from (0, 0) to (1, 1): + +```js +$.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } }); +``` + +The plot function immediately draws the chart and then returns a plot +object with a couple of methods. + + +## What's with the name? ## + +First: it's pronounced with a short o, like "plot". Not like "flawed". + +So "Flot" rhymes with "plot". + +And if you look up "flot" in a Danish-to-English dictionary, some of +the words that come up are "good-looking", "attractive", "stylish", +"smart", "impressive", "extravagant". One of the main goals with Flot +is pretty looks. + + +## Notes about the examples ## + +In order to have a useful, functional example of time-series plots using time +zones, date.js from [timezone-js][timezone-js] (released under the Apache 2.0 +license) and the [Olson][olson] time zone database (released to the public +domain) have been included in the examples directory.
