The angular scale is commonly used in polar charts that use polar coordinates to represent data. In a polar coordinate system, each point is
represented by an angle and distance from a central point. The angular scale is used to show the angle components of such points, usually
expressed in degrees or grads. The angular scale implementation in the chart supports proper automatic step calculation considering the different
cycles of angles and grads (360 vs 400), proper automatic label overlap detection, and other features. In addition, the angular scale can be
positioned in various ways on the polar plot.
