Chart Series: Pie Delphi / C++ Builder RAD IDE Version:

Description yeray alonso 2017-01-31 03:31:51 EST 
Under some circumstances, some marks may not be drawn.
In the following example, the "Lamps" mark isn't drawn if you draw the chart before setting the OtherSlice.Value (it is drawn if you set it before drawing the chart).

Broken since v2015.14.

uses Chart, Series;

var Chart1: TChart;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1:=TChart.Create(Self);
  Chart1.Parent:=Self;
  Chart1.Align:=alClient;

  Chart1.View3D:=False;

  with Chart1.AddSeries(TPieSeries) as TPieSeries do
  begin
    AddPie(100, 'Cars');
    AddPie(150, 'Phones');
    AddPie(200, 'Tables');
    AddPie(250, 'Monitors');
    AddPie(300, 'Lamps');
    AddPie(350, 'Keyboards');
    AddPie(400, 'Bikes');
    AddPie(450, 'Chairs');

    OtherSlice.Style:=poBelowPercent;

    Chart1.Draw;
    OtherSlice.Value:=10;
  end;
end;
