/**
|
||
|
|
* Class: $.jqplot.DonutRenderer
|
||
|
|
* Plugin renderer to draw a donut chart.
|
||
|
|
* x values, if present, will be used as slice labels.
|
||
|
|
* y values give slice size.
|
||
|
|
*
|
||
|
|
* To use this renderer, you need to include the
|
||
|
|
* donut renderer plugin, for example:
|
||
|
|
*
|
||
|
|
* > <script type="text/javascript" src="plugins/jqplot.donutRenderer.js"></script>
|
||
|
|
*
|
||
|
|
* Properties described here are passed into the $.jqplot function
|
||
|
|
* as options on the series renderer. For example:
|
||
|
|
*
|
||
|
|
* > plot2 = $.jqplot('chart2', [s1, s2], {
|
||
|
|
* > seriesDefaults: {
|
||
|
|
* > renderer:$.jqplot.DonutRenderer,
|
||
|
|
* > rendererOptions:{
|
||
|
|
* > sliceMargin: 2,
|
||
|
|
* > innerDiameter: 110,
|
||
|
|
* > startAngle: -90
|
||
|
|
* > }
|
||
|
|
* > }
|
||
|
|
* > });
|
||
|
|
*
|
||
|
|
* A donut plot will trigger events on the plot target
|
||
|
|
* according to user interaction. All events return the event object,
|
||
|
|
* the series index, the point (slice) index, and the point data for
|
||
|
|
* the appropriate slice.
|
||
|
|
*
|
||
|
|
* 'jqplotDataMouseOver' - triggered when user mouseing over a slice.
|
||
|
|
* 'jqplotDataHighlight' - triggered the first time user mouses over a slice,
|
||
|
|
* if highlighting is enabled.
|
||
|
|
* 'jqplotDataUnhighlight' - triggered when a user moves the mouse out of
|
||
|
|
* a highlighted slice.
|
||
|
|
* 'jqplotDataClick' - triggered when the user clicks on a slice.
|
||
|
|
* 'jqplotDataRightClick' - tiggered when the user right clicks on a slice if
|
||
|
|
* the "captureRightClick" option is set to true on the plot.
