/**
* A chart engine implemented with JFreeChart.
*
* This is the JFreeChart base chart engine implementation. All chart would
* support drilldown by providing Area hot spots. Each Area would callback to
* {@link org.zkoss.zul.event.ChartAreaListener} class that application developers
* can do processing on each area.
*
* Note that useful {@link org.zkoss.zul.ChartModel} information is put in
* Area's custom attribute Map so you can retrieve them by calling Area's
* getAttribute(key) method and use them in drilldown function. Following is
* the table of keys for different ChartModel.
*
*
* model key {@link PieModel} entity category value {@link CategoryModel} entity series category value {@link XYModel} entity series x y {@link HiLoModel} entity series date open high low close volumn
* Following is the explanation for each key:
*
* - entity: entity is used to distinguish the differnt entities on a
* chart. It might be TITLE, CATEGORY, DATA, LEGEND. The most important
* entity might be DATA entity where the real chart data point is located.
* For example, the DATA Area is each slice in a Pie chart.
* - category: category name of the associated data.
* - value: value of the associated data.
* - series: series name of the associated data.
* - x: x value of the XYModel
* - y: y value of the XYModel
* - date, open, high, low, close, volumn: data of the HiLoModel
*
*
* See also jFreeChart.
