ValueIndex parameter in custom function's OnCalculate event. [created:2010-11-03T10:23:36.000+01:00 reported by:narcis@steema.com reported in version:2010.01.11004 (TeeChart VCL)]

Added a new property to TCustomTeeFunction:

ValueIndex : Integer

(Default value is -1, meaning it has no valid value).

At function OnCalculateEvent, ValueIndex goes from 0 to NumPoints-1

procedure TForm1.TeeFunction1Calculate(Sender: TCustomTeeFunction;
  const x: Double; var y: Double);
begin
  y:=x+TeeFunction1.ValueIndex;
end;
