TChartAxis.OnDrawLabel event handler is not called with the actual label value and the label value returned by the OnDrawLabel event handler is ignored.

I guess the source code in TeEngine.pas, line 5036:

  if Assigned(FOnDrawLabel) then
     FOnDrawLabel(Self,X,Y,tmpZ,tmpSt,tmpDraw);

Has to patched in the following way:

  if Assigned(FOnDrawLabel) then
  begin
    tmpSt:=Format.Text;
    FOnDrawLabel(Self,X,Y,tmpZ,tmpSt,tmpDraw);
    if tmpDraw then
      Format.Text := tmpSt;
  end;
