I have multiple Pie Series and I would like to label each series from the legend so that users can see which series is which. Any way to do this?

Thanks,

Kevin

Hi Kevin,

Yes, when setting the ChartRect for each pie you can custom write the title to TChart's canvas doing something like this:

Code: Select all

procedure TForm1.Series1BeforeDrawValues(Sender: TObject);
begin
  Chart1.ChartRect:=Rect(10,10,Chart1.Width div 2, Chart1.Height);
  WriteSeriesName((Sender as TChartSeries).Name);
end;

procedure TForm1.Series2BeforeDrawValues(Sender: TObject);
begin
  Chart1.ChartRect:=Rect(Chart1.Width div 2,10,Chart1.Width, Chart1.Height);
  WriteSeriesName((Sender as TChartSeries).Name);
end;

procedure TForm1.WriteSeriesName(Name: String);
var Width: Integer;
begin
  Width:=Chart1.ChartRect.Right-Chart1.ChartRect.Left;
  Chart1.Canvas.TextOut(Chart1.ChartRect.Left+(Width div 2),
                        Chart1.ChartRect.Top+50,Name);
end;
