Question

I am using the MSChart Control to plot some data but I would like to plot two different graphs
together on the same chart. For example, use a Bar chart (series1) with a pie chart (series2)

i am trying to show the two different graphs using one single chart by using following code
It was showing data correct but one problem is i want to show the two graphs (PIE CHART , BAR CHART ) but it was showing (“TWO PIE Charts”)

Can any one help on this

NOte : I am using one chart for all these operations

  private void kpicartmouse_click(object sender, MouseEventArgs e)

Just a guess… won’t this block of code force all your charts to be Pie charts?

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

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

      chartSeries.BackGradientStyle = GradientStyle.DiagonalLeft;
    }

If this doesn’t help, then try breaking your code down into smaller methods, then commenting each bit out in turn – then you’ll be able to understand what each bit does.
