How Could I get the position (relativing to Form or DeskTop coordinate system ) of some point(x,y) of series?

For Example,I want to get the postion of Point(100,100) of Series1,that relatives to Form or DeskTop coordinate system.

Thansks!

Hi wwp3321,

TeeChart provides methods for calculating this positions relative to the chart but you can get form relative positions adding chart position, for example:

Code: Select all

procedure TForm1.Button1Click(Sender: TObject);
var X, Y: Integer;
begin
  X:=Series1.CalcXPosValue(100);
  Y:=Series1.CalcYPosValue(100);

  X:=X+Chart1.Left;
  Y:=Y+Chart1.Top;

  Chart1.Title.Text[0]:=IntToStr(X) + ', ' + IntToStr(Y);
end;
