TContourSeries-custom Levels

[Andy]

Hello !

I use TeeChartPro 7 Vcl.

First I began with TColorGridSeries and figured out how to configure custom Palette-Levels. This workes fine.

Now I want to adapt this feature to contour-series. I want to reconfigure its Levels (Isoline numbers).

In the TeeChartPro demo I found following code

Code: Select all

procedure TContourLevels.CheckBox1Click(Sender: TObject);
begin
  Series1.AutomaticLevels:=not CheckBox1.Checked;
  if not Series1.AutomaticLevels then AddCustomLevels;
end;

Procedure TContourLevels.AddCustomLevels;
begin
  Series1.NumLevels:=10;
  Series1.CreateAutoLevels;
  With Series1.Levels do
  begin
    Items[0].UpToValue:=-1;
    Items[1].UpToValue:=-0.8;
    Items[2].UpToValue:=-0.6;
    Items[3].UpToValue:=-0.4;
    Items[4].UpToValue:=-0.2;
    Items[5].UpToValue:= 0;
    Items[6].UpToValue:= 0.2;
    Items[7].UpToValue:= 0.4;
    Items[8].UpToValue:= 0.6;
    Items[9].UpToValue:= 0.8;
  end;
end;

But this work not here in C++;

Code: Select all

    	
ContourSer->AutomaticLevels=false;
ContourSer->NumLevels=10;
 ContourSer->CreateAutoLevels();
int c=ContourSer->Levels->Count;         ///<  c  ist  0   and not 10 !!!! 

The Levels are not filled so that I cannot manipulate its UpToValues.

What the problem???

Bye

Hello Andy,

I'm afraid you are right. It seems that, for some reason, the CreateAutoLevels in C++ doesn't create the levels as in Delphi. I've added it to the defect list to be investigated asap (TV52015501).

I am having the exact same problem using recently purchaced TeeChart Pro v2011/12. Has this been fixed?

Hi,

Has this been fixed?

I'm afraid not. I've incremented the ticket priority.

Looks like this is the same problem as defect TV52011361, which I have been waiting for 5 years to be fixed. So I wouldn't hold your breath.
