Drawing on a chart

Hi,

I wish to draw text on a chart when the CursorChangeEvent fires.

I am thinking the best way to do this is to create a custom event which inherits from the AfterDraw event which I can then call when the CursorChangeEvent fires. However I can't find what event class the AfterDraw event uses to inherit from.

Is this the best way to do it, or is there a simpler solution?

Thanks in advance.

Hi Agrilink,

You can try implementing the code in the AfterDraw event and if the CursorChangeEvent doesn't fire AfterDraw event, in the CursorChangeEvent, call tChart1.Invalidate() or Bitmap bmp=tChart1.Bitmap to force the chart being redrawn.
