Hilighting pointrs on Tlineseries

[Thomas Klingler]

D6 with TChart 7, chart with about 20 Tlineseries, drawn as lines with distinct points. User can click on any point and pull up information about that point using the method below-

procedure TMainForm.series2Click(Sender: TChartSeries; ValueIndex: Integer;
Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
begin
//do something with valueindex here
Chart.CancelMouse:=True;
end;

What I need to be able to do is to highlight the selected point, it could take on another colour or it could become a different size to the other points in that series. Is there a way to do this please?

thanks
Sean.

Hi Sean,

Yes, you can do the code line above to change the selected point color.

Code: Select all

Sender.ValueColor[ValueIndex]:=clBlue;
