Description yeray alonso 2016-01-25 07:57:09 EST 
Having a TreeMapSeries with some small values to be drawn on the right, they are drawn as vertical lines out of their ancestor parent shape rectangle; probably due to the margin between shapes.

This happens on GDI but not in GDIPlus.
Happens since the first release of the series, in v2010.


uses Chart, TeeConst, TeeTreeMapSeries, TeCanvas, TeeTools;

var Chart1: TChart;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Caption:=TeeMsg_Version;
  Chart1:=TChart.Create(Self);

  with Chart1 do
  begin
    Parent:=Self;
    Align:=alClient;
    Canvas:=TTeeCanvas3D.Create;

    with Chart1.AddSeries(TTreeMapSeries) as TTreeMapSeries do
    begin
      Add(100,'first');
      Add(100,'second', 0, clWhite);
      Add(100,'third', 0, clWhite);
      Add(10,'fourth', 0, clWhite);
      Add(1,'fifth', 3, clWhite);
      Add(1,'sixth', 0, clWhite);
      Add(1,'seventh', 5, clWhite);
      Add(1,'eighth', 6, clWhite);
      Add(1,'ninth', 7, clWhite);
    end;
  end;
