/**
|
|
* Class: $.jqplot.PointLabels
|
|
* Plugin for putting labels at the data points.
|
|
*
|
|
* To use this plugin, include the js
|
|
* file in your source:
|
|
*
|
|
* > <script type="text/javascript" src="plugins/jqplot.pointLabels.js"></script>
|
|
*
|
|
* By default, the last value in the data ponit array in the data series is used
|
|
* for the label. For most series renderers, extra data can be added to the
|
|
* data point arrays and the last value will be used as the label.
|
|
*
|
|
* For instance,
|
|
* this series:
|
|
*
|
|
* > [[1,4], [3,5], [7,2]]
|
|
*
|
|
* Would, by default, use the y values in the labels.
|
|
* Extra data can be added to the series like so:
|
|
*
|
|
* > [[1,4,'mid'], [3 5,'hi'], [7,2,'low']]
|
|
*
|
|
* And now the point labels would be 'mid', 'low', and 'hi'.
|
|
*
|
|
* Options to the point labels and a custom labels array can be passed into the
|
|
* "pointLabels" option on the series option like so:
|
|
*
|
|
* > series:[{pointLabels:{
|
|
* > labels:['mid', 'hi', 'low'],
|
|
* > location:'se',
|
|
* > ypadding: 12
|
|
* > }
|
|
* > }]
|
|
*
|
|
* A custom labels array in the options takes precendence over any labels
|
|
* in the series data. If you have a custom labels array in the options,
|
|
* but still want to use values from the series array as labels, set the
|
|
* "labelsFromSeries" option to true.
|
|
*
|
|
* By default, html entities (<, >, etc.) are escaped in point labels.
|
|
* If you want to include actual html markup in the labels,
|
|
* set the "escapeHTML" option to false.
|
|
*
