New Post: AngleAxis labels

I would like to have 0 degrees at the bottom of the polar plot (Example here, don't mind E and W). I've been playing with StartAngle and EndAgnle but I can't work this out. Is this even possible?

This is the code:

            var angleAxis = new AngleAxis();
            angleAxis.MajorStep = 45;
            angleAxis.Minimum = -180;
            angleAxis.Maximum = 180;
            angleAxis.MinorStep = 9;
            plotModel.Axes.Add(angleAxis);

Everything is almost ok with this, but 0 degrees are postion at left and 180 at right, I want 0 to be bottom and 180 top.
