Description yeray alonso 2018-10-15 04:33:42 EDT 
The fix for #2006 seems to create this issue


uses Series, TeeConst;

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Caption:=TeeMsg_Version;
  Chart1.Legend.Hide;
  Chart1.View3D:=False;

  with Chart1.AddSeries(TFastLineSeries) as TFastLineSeries do
  begin
    for i:=0 to 19 do
      if i=10 then
        AddNull(5)
      else
        Add(10);

    TreatNulls:=tnDontPaint;
  end;

  Chart1.Axes.Left.SetMinMax(0,15);
end;
