Hi guzial,

Yes, this is a known limitation. Existing PDF export filter does not support transparency (missing pdf implementation). We have this on our wish list for next major TeeChart release. In the meantime the workaround is to disable (set it to 0) the transparency.

Hi Richard,

You should use something as following:

Code: Select all

ChartListBox1.ClearItems;
ChartListBox1.AddItem('Series3',Series3);
ChartListBox1.AddItem('Series4',Series4);
ChartListBox1.AddItem('Series5',Series5);

Hi guzial,

We're sorry but you should use TLineSeries to achieve ColorEachPoint to work properly.

Hello guzial, Ensure that you have set the following properties to true: YourLineSeries.ColorEachLine:=true; YourLineSeries.ColorEachPoint:=true; If this doesn't help, could you please send us a simple example project we can run "as-is" to reproduce the problem here?

Hello drueter,
You can use OnClick event as follows:

Code: Select all

procedure TForm1.Series1Click(Sender: TChartSeries; ValueIndex: Integer;
  Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
begin
  Chart1.Title.Caption := 'Clicked Pie: ' + inttostr(Series1.CalcClickedPie(X,Y));
end;
