Hi Alex,
Yes, with OnGetMarkText event, from your series, you can customize its mark text as you want:
Code: Select all
procedure TForm1.FormCreate(Sender: TObject);
begin
Series1.Marks.Visible := True;
end;
procedure TForm1.Series1GetMarkText(Sender: TChartSeries;
ValueIndex: Integer; var MarkText: String);
begin
MarkText := Sender.Name + ' X: ' + floattostr(Sender.XValues.Items[ValueIndex]) +
' Y: ' + floattostr(Sender.YValues.Items[ValueIndex]);
end;

Hi Alex,
It can be customized programmatically using the OnGetText event.

Hi Alex,
You just need to add a TMarksTipTool to your application and make series marks not visible. The code Yeray posted will modify tool's text as well, for example:
Code: Select all
procedure TForm1.FormCreate(Sender: TObject);
begin
Series1.Marks.Visible := False;
end;
procedure TForm1.Series1GetMarkText(Sender: TChartSeries;
ValueIndex: Integer; var MarkText: String);
begin
MarkText := Sender.Name + ' X: ' + FloatToStr(Sender.XValues.Items[ValueIndex]) +
' Y: ' + FloatToStr(Sender.YValues.Items[ValueIndex]);
end;
