Hello,
I'm have got a complex chart with many Series. Now I want to add something with Printer.Canvas while Printing with PrinterPartialCanvas. so i need the Pixel Position of the Axes while Printing the Chart, because e.g. BottomAxis.AxisPos is only for the Chart on screen. But I want to work with PrinterPartialCanvas. No, Metafiles!
Thank you very much

Hi Bent,

to know the pixel position you will have to use similar code to the following when you print :

Code: Select all

: var P : TPoint;
if Chart1.Printing then
begin
  P.X:=Chart1.Axes.Left.PosAxis;
  P.Y:=Chart1.Axes.Bottom.PosAxis;
  LPToDP(Chart1.Canvas.ReferenceCanvas.Handle,P,1);
  // Now you have "P" point with physical coordinates
end;

You can find more info about LptoDP method at :
