Syncfusion图表问题

Question

我正在使用Visual Studio 2008，SyncFusion Essential Studio企业版（WinForms）版本7.203.0.20。

我想知道是否有人可以帮我解决一个小问题：我怎样才能为我的折线图中的每一行指定一个自定义颜色？

Answer 1

要为线图设置颜色：

this.chartControl1.Series[0].Style.Interior = new BrushInfo(GradientStyle.Vertical, Color.Red, Color.Orange);

这里是一个帮助链接 - http://www.syncfusion.com/support/kb/83/How-do-I-set-the-Interior-colors-for-the-chart-series-data-points

如果你想单独连接线是不同颜色的，那么你需要处理ChartSeries.PrepareStyle事件如下：

this.chartControl1.Series[0].PrepareStyle += new ChartPrepareStyleInfoHandler(series_PrepareStyle);

void series_PrepareStyle(object sender, ChartPrepareStyleInfoEventArgs args) { //Specifying different Colors for data points using Prepare style event ChartSeries series = sender as ChartSeries; if (series != null) { if (this.chartControl1.Series[0].Type.ToString() == "Line") { if (args.Index == 0) args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Red); else if (args.Index == 1) args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Green); else if (args.Index == 2) args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Blue); else if (args.Index == 3) args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Yellow); else if (args.Index == 4)
