/**
|
|
* Class: $.jqplot.DateAxisRenderer
|
|
* A plugin for a jqPlot to render an axis as a series of date values.
|
|
* This renderer has no options beyond those supplied by the <Axis> class.
|
|
* It supplies it's own tick formatter, so the tickOptions.formatter option
|
|
* should not be overridden.
|
|
*
|
|
* Thanks to Ken Synder for his enhanced Date instance methods which are
|
|
* included with this code <http://kendsnyder.com/sandbox/date/>.
|
|
*
|
|
* To use this renderer, include the plugin in your source
|
|
* > <script type="text/javascript" language="javascript" src="plugins/jqplot.dateAxisRenderer.js"></script>
|
|
*
|
|
* and supply the appropriate options to your plot
|
|
*
|
|
* > {axes:{xaxis:{renderer:$.jqplot.DateAxisRenderer}}}
|
|
*
|
|
* Dates can be passed into the axis in almost any recognizable value and
|
|
* will be parsed. They will be rendered on the axis in the format
|
|
* specified by tickOptions.formatString. e.g. tickOptions.formatString = '%Y-%m-%d'.
|
|
*
|
|
* Accecptable format codes
|
