Description yeray alonso 2013-11-20 10:36:50 EST 
Probably related to TV52015179, but probably a particular case not contemplated in the fix for TV52015179.
The follwing code produces overlapping labels in the bottom axis:
procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
    value: Double;
begin
  Chart1.View3D := False;
  chart1.Axes.Bottom.DateTimeFormat := 'dd/mm/yy';
  Chart1.AddSeries(TFastLineSeries);
  (Chart1.Series[0] as TFastLineSeries).TreatNulls := tnSkip;
  Chart1.Series[0].XValues.DateTime := False;
  value := 45;
  For i := 300 To 720 do
  begin
    value := value + 0.03 * (Random - random);
    Chart1.Series[0].AddXY(i, value, FormatDateTime('dd/mm/yy', Now - 365 + i));
  end;
  Chart1.AddSeries(TFastLineSeries);
  (Chart1.Series[1] as TFastLineSeries).TreatNulls := tnSkip;
  Chart1.Series[1].XValues.DateTime := False;
  value := 45;
  For i := 1 To 720 do
  begin
    value := value + 0.03 * (Random - random);
    Chart1.Series[1].AddXY(i, value, FormatDateTime('dd/mm/yy', Now - 720 + i));
  end;
end;
