Description sandra pazos 2014-07-28 08:24:49 EDT 
LineSeries Outline transparency doesn't work fine in GDI Canvas. The code below reproduces the exactly problem. It works fine in GDI+. 

procedure TForm2.FormCreate(Sender: TObject);
begin
   Chart1.View3D:=false;
   CheckBox1.Checked := true;
   Series1 := TBarSeries.Create(Self);
   Chart1.AddSeries(Series1);
   Series1.FillSampleValues(50);
   Series1.Marks.Visible := false;
   Series1.Color := clGreen;
   Series1.Transparency := 40;
   Series2 := TLineSeries.Create(Self);
   Series2.FillSampleValues(50);
   Chart1.AddSeries(Series2);
   Series2.Color := clBlack;
   Series2.OutLine.Visible:=true;
   Series2.OutLine.Color := clYellow;
   Series2.OutLine.Width := 3;
   Series2.OutLine.Color := Chart1.Canvas.ColorFrom(clYellow,125);
   Series2.Pen.Style := psDash;
   Series2.Pen.Width := 2;
   ChartEditor1.Chart := Chart1;
end;
