Pie Chart Mirrors itself when export to pdf

[Dave Koppe]

I'm having an issue when exporting a report to pdf. The Pie chart mirrors itself. Any ideas?

Hello Dave Koppe,

This could happen if you populate the chart series manually and do not clear them. Currently every time the report is previewed, paged or exported it is processed and rendered from scratch and this way the series would be doubled, tripled etc depending on how many times you print/export. Add the following line to your chart's NeedDataSource event:

private void chart1_NeedDataSource(object sender, System.EventArgs e)
   {
     chart1.Series.Clear();
     .......
     Telerik.Reporting.Processing.Chart procChart = (Telerik.Reporting.Processing.Chart)sender;
     procChart.DataSource = <your_datasource>;
   }

Hope this helps.

Sincerely yours,
Steve
