See the project attached.

- If you run it as-is (ClockWiseLabels=false at designtime) everything works as expected.

- If you check the ClockWise checkbox (at Series\Format\Labels\Options tab), both the circle labels and the series have rotated (which is correct). Now, when you run, you'll see the series has moved 180 degrees (which is wrong).

As a temporal workaround, you can reload the data making sure ClockWiseLabels=false and set it to true after it:

procedure TForm1.FormCreate(Sender: TObject);
begin
  Series1.ClockWiseLabels:=False;
  Series1.CheckDataSource;
  Series1.ClockWiseLabels:=True;
end;
