"Hi - Which TeeChart version are you using ? Using TeeChart v7 the following code worked perfectly:
Code:
procedure TForm1.Chart1AfterDraw(Sender: TObject);
begin
Chart1.Canvas.UnClipRectangle;
end;
procedure TForm1.Chart1BeforeDrawSeries(Sender: TObject);
begin
Chart1.Canvas.ClipEllipse(Rect(50,50,250,200),false);
end;
I've used Chart OnBeforeDrawSeries and OnAfterDraw events to perform the clipping on oval region (limited by Rect rectangle))."

Thanks for your reply. Forgive me for not indicating that I am using TeeChart v6 and Delphi v7. In TeeChart v6 the ClipEllipse() procedure is found in the TeCanvas.pas unit and is not associated with any particular class.

Hi, Tony.

Still.... even with Teechart v6.01 it can be done with no problem:

Code: Select all

procedure TForm1.Chart1AfterDraw(Sender: TObject);
begin
  Chart1.Canvas.UnClipRectangle;
end;

procedure TForm1.Chart1BeforeDrawSeries(Sender: TObject);
begin
  ClipEllipse(Chart1.Canvas,Rect(50,50,250,200));
end;
