|
* 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. |
