Hi Minas,

Yes, you can achieve what you request using OnGetCircleLabel event as shown here:

Code: Select all

procedure TForm1.Series1GetCircleLabel(Sender: TCustomPolarSeries;
  const Angle: Double; Index: Integer; var Text: String);
begin
  if Angle = 0 then begin Text:='E'; exit; end;
  if Angle = 90 then begin Text:='N'; exit; end;
  if Angle = 180 then begin Text:='W'; exit; end;
  if Angle = 270 then begin Text:='S'; exit; end;

  Text:='';
end;
