Description yeray alonso 2014-05-09 03:57:19 EDT 
With the following code you'll see the labels are clockWise, but the points are drawn as if the labels weren't. So the first value (10,50) is drawn at label 350, etc

  Chart1.View3D:=false;

  Chart1.Axes.Bottom.SetMinMax(0,100);
  Chart1.Axes.Left.SetMinMax(0,100);

  with Chart1.AddSeries(TPolarSeries) as TPolarSeries do
  begin
    Brush.Style:=bsClear;
    Pen.Visible:=false;

    Rotate(90);
    ClockWiseLabels:=true;


    AddPolar(10,50);
    AddPolar(15,60);
    AddPolar(20,70);
    AddPolar(25,80);
    AddPolar(30,90);
  end;

A workaround is to change the sign of the Angles:

    AddPolar(-10,50);
    AddPolar(-15,60);
    AddPolar(-20,70);
    AddPolar(-25,80);
    AddPolar(-30,90);

I have spent quite some time on this problem. It only got noticed after being accused by a customer of displaying entirely wrong data. Please upgrade the priority of "Enhancement" to something more serious.
