Polar Graphs
Polar graphs are like scatter graphs that use polar coordinates. The data must be arranged in group-wise pairs. The first group contains the phase (angle) data, in degrees. The second group contains magnitude information.
The polar axis (CX_AXIS_POLAR) consists of a series on concentric, labeled circles and a set of radial lines at 22.5-degree intervals, starting at 0 degrees on the vertical and increasing clockwise. This default spacing of the radial lines can be changed by a simple override of SRGraphDisplay::DrawPolarLabels() and DrawPolarAxis().
Two types of polar graphs are provided:
