OWC饼图的颜色如何设定？
我如下设定，但为什么chDimCategories(kkk,ttt)两个能显示，而chDimValues只现实42,而34为什么没有显示出来？
objChart.Type=OWC.ChartChartTypeEnum.chChartTypePie;
objChart.SeriesCollection.Add(0);
objChart.SeriesCollection[0].SetData (OWC.ChartDimensionsEnum.chDimCategories,
(int)OWC.ChartSpecialDataSourcesEnum.chDataLiteral, "kkk");
objChart.SeriesCollection[0].SetData(OWC.ChartDimensionsEnum.chDimValues,
(int)OWC.ChartSpecialDataSourcesEnum.chDataLiteral,42);
object ob = "#66FF66";
objChart.SeriesCollection[0].Interior.set_Color(ref ob);

objChart.SeriesCollection.Add(1);
objChart.SeriesCollection[1].SetData (OWC.ChartDimensionsEnum.chDimCategories,
(int)OWC.ChartSpecialDataSourcesEnum.chDataLiteral, "ttt");
objChart.SeriesCollection[1].SetData(OWC.ChartDimensionsEnum.chDimValues,
(int)OWC.ChartSpecialDataSourcesEnum.chDataLiteral,34);
object ob = "#0000FF";
objChart.SeriesCollection[i].Interior.set_Color(ref ob);
