你这个wmrpc代码能分享一下么，图是怎么画出来的， 我用SpiderWebPlot 画出的图，线条都是直线。

非常感谢！！ 但你能不能把你自己封装的类都能分享一下吗？？ChartCreater，WMRadarPlotCreater，XYSeriesCollectionModel，WMPolarPlot。

回复匿名网友：其它的类都是JFreeChart组件包含的 有兴趣查阅下文档 雷达图确定一个点在什么位置依靠一组值[0<=角度<=360,数据轴MIN<=数值<=数据轴MAx] 通常将这些描述点位置的信息封装到对象(如)进而组成序列来描述多个点 如XYSeriesCollectionModel就像集合类收集了若干XYSeries对象
