Install teechart 7.12 on delphi 7

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

 Series3.AddXY(tc,y1);   
 Series3.AddXY(tc,y2);

Of course, I tried this :

Code: Select all

  Series3.AddXY(Series1.XValue[Trunc(tc)], Series1.YValue[Trunc(y1)]);   
  Series3.AddXY(Series2.XValue[Trunc(tc)], Series2.YValue[Trunc(y2)]);

But, is not good..

Thank you Narcis !

another question :
