Hello,

Why I have to check the boxes of TeeChart components to see them appear under delphi 7, windows 10 pro with
TeeChart 7.12?
However, I removed before installation, the old version of TChart and the Tee70
?
Thank you for your help

Hi Narcis,

thank you for your attention
but

Why is it necessary to specify 'X' instead of 'q' as the file column. Csv is defined by 1 or 2?

Thank you for your help

Hi Narcis, here is my code : PROCEDURE TForm1.TeeFunction1Calculate(Sender: TCustomTeeFunction; CONST x: Double; VAR y: Double); BEGIN IF (Edit1.Text = Null) OR (Edit1.Text = '') THEN exit; y := StrToFloat(Edit1.Text); END; PROCEDURE TForm1.Edit1KeyDown(Sender: TObject; VAR Key: Word; Shift: TShiftS...

Thank you Narcis !

another question :

how to revive the event "TeeFunction1Calculate"
because neither the repaint nor the invalidate work?

Didier

Hi Narcis, I would build a program in delphi with TeeChart so that the user can enter the aquatic function and click on a display its image. How will introduce the equation y:= f (x) in the code of the event TForm1.TeeFunction1Calculate (Sender: TCustomTeeFunction; CONST x: Double; VAR y: Double); k...
