How to get X Y coordinates (without moving mouse)

Question

with MouseMove procedure, I can get X and Y pos. by this code:

///////////

var

  XVal: double;
  YVal: double;

begin

  XVal:=Chart1.Axes.Bottom.CalcPosPoint(X);
  YVal:=Chart1.Axes.Left.CalcPosPoint(Y);

  Chart1.Title.Text[0]:=FormatFloat('#.##', XVal) + ' - ' + FormatFloat('#.##', YVal);
end;

////////////

It's OK. But I would like get the X and Y coordinates of a series1.Value (single value, it is 'somewhere' on the chart) by clicking a (separate) button and not by moving the mouse above this value. Maybe it is a very simple question. Thanks.

If you're clicking on a button, how is the program supposed to know what object you want the position of? — lurker, Dec 17 '13 at 21:01

You can use functions of series:

CalcXPos - to get screen X-coordinate by index of value (in serie) CalcXPosValue - to get screen X-coordinate by value

(CalcYPos/CalcYPosValue for Y-coordinate)
