Description yeray alonso 2014-06-26 06:07:49 EDT 
Put a TChart and a TeeCommander on a form and the code below.
From v2014.11, the text looks a bit bigger in GDI and not correctly matching the shape rectangle.
Also, if you open the editor and move the slice for the Mark Font Size, you'll see it is completely buggy: You set a bigger size and the font looks smaller, and the mark shape doesn't fit the text at all.

uses TeeMapSeries, TeCanvas;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.Canvas:=TTeeCanvas3D.Create;

  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;

  with Chart1.AddSeries(TMapSeries) as TMapSeries do
  begin
    Marks.Visible:=true;

    with Shapes.Add() do
    begin
      Text := 'line 1'+sLineBreak+'line 2'+sLineBreak+'line 3';
      Points.AddArray([0, 0, 1, 1], [0, 1, 1, 0]);
    end;
  end;
end;
