Description yeray alonso 2019-10-11 08:02:12 EDT 
In this simple example, the GetMarkText event isn't fired.

uses TeeSurfa;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=False;
  Chart1.Legend.Hide;

  with TContourSeries(Chart1.AddSeries(TContourSeries)) do
  begin
    FillSampleValues;
    Marks.Show;
    OnGetMarkText:=GetMarkText;
  end;
end;

procedure TForm1.GetMarkText(Sender: TChartSeries;
  ValueIndex: Integer; var MarkText: string);
begin
  MarkText := MarkText + ' %';
end;
