Hi GotoXY,
First of all please bear in mind that for using stacking all series need to have the same number of points and same X values. Having that in mind, does this also occur using v8.07 which is the latest build available at the client area? If the problem persists can you please attach a simple example project we can run "as-is" to reproduce the problem here?
Thanks in advance.

Oh ok, ill check the points count but for im sure all X Values are the same.
I dont have time right now to move to 8.0.7 because i had to change some stuff in your code to make it work like i need it (ex: DATA :Pointer; in a Series to keep tracks of lots of information)

Thanks again, really appreciate your Superman Support

Hi GotoXY,
Ok, thanks for the info. If you have a simple application with which we can reproduce the issue here we will gladly look at it.

I made one for you with 2 stacked groups. At least now, i know i have to verify how many points i have for each series and make them equal so that way it work perfectly.

Hi GoToXY,
Thanks for the example project. In those cases where you don't want to plot a value for a series you should either add a zero point or a null point, for example:
Code: Select all
procedure TForm1.FormCreate(Sender: TObject);
Var
TheDate : TDate;
Ctr : Integer;
begin
TheDate := EncodeDate(YearOf(Now),MonthOf(Now),1);
For Ctr := 1 To 12 Do
Begin
Chart1[0].AddXY(TheDate,Random(50)+50,MonthNames[MonthOf(TheDate)]);
Chart1[1].AddXY(TheDate,Random(10)+10);
If (Ctr Mod 2 = 0) Then
Chart1[2].AddXY(TheDate,Random(10)+10)
else
Chart1[2].AddNullXY(TheDate,0);
If (Ctr Mod 3 = 0) Then
Chart1[3].AddXY(TheDate,Random(10)+10)
else
Chart1[3].AddNullXY(TheDate,0);
If (Ctr Mod 4 = 0) Then
Chart1[4].AddXY(TheDate,Random(10)+10)
else
Chart1[4].AddNullXY(TheDate,0);
Chart1[5].AddXY(TheDate,Random(10)+10);
TheDate := IncMonth(TheDate);
End;
end;

Yes this is exactly what ive done after i knew it was a points number issue. I had to do the same thing for the function (add,div etc..) to solve half of the problem.
