Having two TPolarSeries in a chart and a TTeeCommander, of you try to rotate the chart, only one of the series rotates.

Ie, put a TChart and a TTeeCommander on a form and use this code:

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  with Chart1 do
  begin
    View3D := false;
    Chart3DPercent := 0;
    Gradient.Visible:=false;
    Title.Visible:=false;
    Legend.Visible:=false;
  end;

  for i:=0 to 1 do
    with Chart1.AddSeries(TPolarSeries) as TPolarSeries do
    begin
      FillSampleValues;
      Pointer.Visible:=false;
      Brush.Clear;
      Pen.Color:=Color;
      Pen.Width:=2;
      CircleBrush.Clear;
    end;
end;
