Description narcís calvet 2013-11-20 10:03:27 EST 
Pie an donut series are not painted correctly with some rotation angles. This occurs both in GDI and GDI+. Code snippet below to reproduce the issue and attached some screenshots.
uses Series, TeeDonut, TeeGDIPlus, TeCanvas;

procedure TForm1.FormCreate(Sender: TObject);
var Series1 : TDonutSeries;
 g : TGDIPlusCanvas;
begin
 Series1:=TDonutSeries.Create(Self);
 Series1.EdgeStyle:=edFlat;
 Series1.BevelPercent:=30;
 Series1.DonutPercent:=40;
 Series1.AddPie(849, 'Cars');
 Series1.AddPie(51, 'Tables');
 Series1.AddPie(51, 'Phones');

 g:=TGDIPlusCanvas.Create;
 Chart1.Canvas:=g;
 Chart1.AddSeries(Series1);
 Chart1.Chart3DPercent:=50;
end;
It works a little better in .NET:
Steema.TeeChart.Styles.Donut donut1 = new Steema.TeeChart.Styles.Donut(tChart1.Chart);

 donut1.EdgeStyle = Steema.TeeChart.Drawing.EdgeStyles.Flat;
 donut1.BevelPercent = 30;
 donut1.DonutPercent = 40;
 donut1.Add(849, "Cars");
 donut1.Add(51, "Tables");
 donut1.Add(51, "Phones");

 tChart1.Aspect.Chart3DPercent = 50; [created:2010-10-15T09:53:26.000+01:00 reported by:narcis@steema.com reported in version:2010.01.11004 (TeeChart VCL)]
