public class PolarGrid

extends java.lang.Object

The polar grid consists of circles painted outwards starting from the center of the polar graph. Each circle's radius length corresponds to the distance from the polar graph center to a tick mark of the horizontal or vertical scale. The polar grid can also display spokes, which are straight lines painted from the graph center towards the outer grid circle. The spokes are displayed at a user-defined angle relative to the right horizontal radius of the polar graph and measured counterclockwise.
