Chart image of overlapping labels and title.

It would be very interesting that axis labels and titles could automatically re-position themselves to not overlap chart walls, axis and series depending on the chart rotation. The problem can be easily reproduce with the code snippet below and observed with the attached image.

uses TeeSurfa, TeeTools;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.AddSeries(TTowerSeries.Create(Self)).FillSampleValues();
  Chart1.Aspect.Orthogonal:=False;
  Chart1.Aspect.Zoom:=80;
  Chart1.Chart3DPercent:=70;
  Chart1.DepthAxis.Visible:=True;
  Chart1.Axes.Bottom.Title.Text:='Bottom axis title';
  Chart1.Axes.Bottom.Title.Font.Color:=clRed;
  Chart1.Axes.Bottom.Title.Font.Size:=20;

  Chart1.Tools.Add(TRotateTool.Create(Self));
end;

procedure TForm1.Chart1GetAxisLabel(Sender: TChartAxis;
  Series: TChartSeries; ValueIndex: Integer; var LabelText: String);
begin
  if Sender <> Chart1.Axes.Left then
    LabelText:='long label text';
end;
