Do you mean "Draw the chart as a circle" or "Draw a circle beside the
chart"?

TChart objects have a Canvas property. Use it. For example:
Code: [Select]PROCEDURE TForm1.Chart1Click(Sender: TObject);
BEGIN
  Chart1.Canvas.EllipseC (X, Y, RadiusX, RadiusY);
END;

Actually, it is much better idea to use TUserDrawnSeries for that.
