3D Polar Plot
The polar axis can be placed at the minimum, maximum or mean value of Zp at the largest radius, at the top or bottom of the plot box, at a user specified location, or it can follow the surface at the perimeter of the data. The polar axis tick mark spacing can be adjusted with the 'TickSpacing' property.
The default polar axis orientation is that zero degrees is along the +X axis and increasing angles are counter-clockwise. The 'PolarDirection' property can be used to change this to a compass style plot with zero degrees along the +Y axis and increasing angles going clockwise around the pole.
Default surface coloring is according to the values in Zp. This can be changed by supplying a matrix the same size as Zp as the value of the 'ColorData' property.
A scaling parameter can be specified to interpolate the data onto a finer or coarser mesh. The output Cartesian data is returned in three matrices.
