Hi,

I have some Pie Charts (TDBChart) where I have grouped slices where the values are less than 5%.

The chart displays just fine, but I want to be able to quickly get the 'X' values for the grouped slice, if the user clicks on the grouped slice. For the non-grouped slices, I get the clicked slice X value using Series.Labels[ValueIndex] in an OnClickSeries event. Obviously if I click on the grouped slice, this approach just gives me the 'Grouped Slices' 'Label' value.

I need the X values for building subsequent SQL statements.

Is there a simple way to get the X values that have been grouped?

Thanks
Clive

Hi Clive,

The code snippet below returns the number of one last additional slice containing all grouped slices. So this is not possible for now. I have added your request to the wish-list to be considered for inclusion in future releases: http://bugs.teechart.net/show_bug.cgi?id=1480

Code: Select all

procedure TForm1.Chart1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
var Index: Integer;
begin
  Index:=Series1.Clicked(X,Y);

  if Index <> -1 then
    Chart1.Title.Text[0] := IntToStr(Index);
end;
