Multi-line axis labels not supported anymore

[Collinor]

In contrast to TeeChart 2012, multi-line axis labels are not supported anymore in TeeChart 2014, May, 12, 2014. Only the first line is used for display of the axis label (see TeeEngine.pas, function TChartAxisTitle.GetCaption).
Even if TChartAxisTitle.GetCaption would return all lines, TCustomTextShape.DoDraw, which actually draws the label, would not draw the lines correctly, if the angle is 90.

Hello Collinor,

Could you arrange for us a simple example where all the problems you are experiencing appear, because we can check the problems here and fix these if is the case?

Thanks in advance,

[Collinor]

Put a TChart on a form and add the following code:

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.MarginBottom := 10;
  Chart1.MarginLeft := 5;
  Chart1.Axes[0].Title.Angle := 0;
  Chart1.Axes[0].Title.Caption := 'Line 1'#13'Line 2'#13'Line 3';
  Chart1.Axes[2].Title.Angle := 90;
  Chart1.Axes[2].Title.Caption := 'Line 1'#13'Line 2'#13'Line 3';
end;

Compile the application once with TeeChart 2012 and once with TeeChart 2014 and then compare the results.
