Here's what I'm attempting: with BarSeries1 do begin Add(2.0, 'Label1', $00C7B189); Add(3.0, 'Label2', $00C7B189); Add(4.0, 'Label3', $005EE9F4); Add(5.0, 'Label4', $005EE9F4); Add(6.0, 'Label5', $009395EE); Add(7.0, 'Label6', $009395EE); end; The resulting legend would be: Label1 (color $00C7B189) Label3 (color $005EE9F4) Label5 (color $009395EE) Using D5 & TChart Standard version 4 Thanks for any help, -- Patrick Hughes Back to top Narcís Calvet Guest Posted: Wed Jan 17, 2007 5:44 pm    Post subject: Re: TChart Legends Hi Patrick, The only way I can think of is using TChart's OnGetLegendText like this: procedure TForm1.Chart1GetLegendText(Sender: TCustomAxisPanel; LegendStyle: TLegendStyle; Index: Integer; var LegendText: String); begin if index mod 2 <> 0 then legendText := '' else legendText := legendText; end; end; -- Best Regards, Narcis Calvet Steema Support Central http://support.steema.com "Important note: If you are a TeeChart registered customer, please post your support questions at Steema's Support monitored Forums for customers: http://support.steema.com for a prompter reply."

The OnGetLegendText event handler wasn't working in my case. void __fastcall TTestReview::TrendChartGetAxisLabel(TChartAxis *Sender, TChartSeries *Series, int ValueIndex, AnsiString &LabelText) { if((ValueIndex % 2) != 0){ LabelText = ""; } } Chuck Yetter "Patrick Hughes" <duhvinci@-RemoveThis-engds.com> wrote in message news:45af9c26 (AT) newsgroups (DOT) borland.com...
