This is how Polar series rendered in v8

Code below doesn't render series correctly. It worked in v8. Included attachments showing the differences between v8 and v2015.

uses TeePolar, TeeConst;

procedure TForm1.FormCreate(Sender: TObject);
var
  Series1: TPolarSeries;
  i: Integer;
begin
  Chart1.View3D:=False;
  Chart1.Title.Text[0]:=TeeMsg_Version;

  Series1:=TPolarSeries.Create(Self);
  Series1.Pointer.Visible:=False;

  for i:=0 to 359 do
    Series1.AddXY(i, random);

  Chart1.AddSeries(Series1);
end;
