  Hi,
  
  with Legacy C1Chart (C1.Win.C1Chart.C1Chart) I was able to show a background Image to the Chart until I start populate it:

  C1_Chart_Test.BackgroundImage = Image.FromFile(…)

  After that I can see the Image in the background.

  With FlexChart, the same method does not shows any Image…

  I also didn0’t find anything in any sample you provided.

  What Am I doing wrong ?

  Thanks

  P.S. “RenderMode” property is set to “DirectX”; the default method works

  Hi fabio,

  Thanks for reporting this issue. We have replicated this issue at our end. This seems like a bug. So, that we have escalated it to the development team. We will inform you whenever we get any update on this. [Internal Tracking Id - C1CHART-2115]

  However, You can do a workaround for the same, by handling rendering event of FlexChart as:

  
  private void FlexChart_Rendering(object sender, RenderEventArgs e)
  {
      var image = Image.FromFile("../../grapecity.png");
      e.Engine.DrawImage(image, 0, 0, flexChart.PlotRect.Width, flexChart.PlotRect.Height);
  }
  
  

  Please refer the attached sample for the same : FlexChartBackgroudImage.zip

  Best Regards,
  
  Nitin.

  Hi NItin,
  
  atm I’ll change the rendermode via code just before populating with series, waiting for the final patch.THanks
