Having a TLineSeries (doesn't happen with a TFastLineSeries), if you set a significant marks arrow, some extra space in the left axis is taken to fot the marks. However, no new axis labels are drawn in the new space.
This worked fine in v2012.05 but in v2012.06. See the images attached
uses Series, TeeConst;
procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.Title.Text.Text:=TeeMsg_Version;
  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;
  with Chart1.AddSeries(TLineSeries) do
  begin
    Add(0);
    Add(1000);
    Marks.ArrowLength:=35;
    Marks.Visible:=true;
  end;
end;
Probably the same:
Having a TLineSeries (doesn't happen with a TFastLineSeries) if you use the MaximumRound property si the Internal Maximum (IMaximum at TChartAxis.CalcRoundScales in TeEngine.pas) is modified, the new label isn't drawn.
procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;
  with Chart1.AddSeries(TLineSeries) do
  begin
    Add(0);
    Add(945);
  end;
  Chart1.LeftAxis.MaximumRound:=true;
end;
