Hello vishwa,

Sorry for the delay. I inform that finally I can reproduce your problem in version 3 and version 4 using a simple code and I have added it in bug list report with number [TF02015956]. We will try to fix it for future maintenance releases of TeeChart.Net.

Hi Sandra,
Please let me know the workaround or any other internal property to know crash has happened so that I can handle it with my own workaround.
Here is what I tried:
While Adding points to surface I keep on checking this property
try
{
Bitmap b = colorGridTChart.Bitmap;
}
if it throws exception; immediatly I change [expand ] the scale limit in catch block so crash was not happening. But it did crash while rotating the TeeChart. For that also I kept this code in TeeChart rotating event to check if crash has happened internally And handled it in catch block in similar wat by expanding scale limit. Since calling this property itself takes time. So rotating of TeeChart became very slow.
So I want to know is there any other lightweight property to check if TeeChart is crashed internally so that I can set workaround without affecting my application performance.

PS: Whenever TeeChart crashes this property also thorws exception but user sees Crash only When we call teeChart.Refresh() method. So before calling Refresh() method I am cheking if crash has occured internally using colorGridTChart.Bitmap property and accordingly change scale limit to avoid that.

Thanks

Hello vishwa,

I am afraid I don't have any workaround for your problem,at the moment, so I only can give you the internal code, where the Overflow exception appears for me.

The problem occurs for me in the class CanvasGDIplus.cs in the method public override void Polygon(params PointDouble[] p) concretely in the lines where there is next:

Code: Select all

 if (Pen.Visible && p.Length > 1)
			{
        //CDI TF02014395
        //g.DrawPolygon(Pen.DrawingPen, P); 
        for (int i = 0; i < P.Length - 1; i++)
        {
          g.DrawLine(Pen.DrawingPen, P[i], P[i + 1]);
        }
			}

I hope will helps it and if you have any other problem let me know.

Thanks,
