在同一个图表上绘制两个不同的图表

Question

我正在使用 MSChart Control 绘制一些数据，但我想绘制两个不同的图表 一起在同一张图表上。例如，使用条形图（系列1）和饼图（系列2）

我试图通过使用以下代码使用一个图表来显示两个不同的图表 它显示的数据正确，但一个问题是我想显示两个图表（饼图、条形图），但它显示（“两个饼图”）

任何人都可以提供帮助吗

注意：我对所有这些使用一张图表运营

  private void kpicartmouse_click(object sender, MouseEventArgs e)

只是猜测......这段代码不会强制您所有的图表都是饼图吗？

    foreach (Series chartSeries in kpiChartControl.Series)
    {
      chartSeries.ChartType = SeriesChartType.Pie;

      chartSeries["PieLabelStyle"] = "Outside";
      chartSeries["DoughnutRadius"] = "30";
      chartSeries["PieDrawingStyle"] = "SoftEdge";

      chartSeries.BackGradientStyle = GradientStyle.DiagonalLeft;
    }

如果这没有帮助，那么尝试将代码分解为更小的方法，然后依次注释每一位 - 然后您将能够理解每一位的作用。
