I have a polar plot depicting 0 - 360 degrees for the angle, and 0 - 90 degrees for the radius.

1. The angles are shown counter-clockwise. How do i change this to clockwise? One post I read said this was impossible, (which is ridiculous), and suggested adding the data backwards and hacking the labels to match. How do I implement this workaround?

2. The radii currently start at 0 in the center and increase to 90 on the edge. How do I reverse this to show 90 in the center, and 0 on the edge? The point of this is to represent objects within a hemisphere overhead (0 - 360 degrees being the azimuth of the object, and 0 - 90 degrees being the elevation from the horizon).

Thanks!
