Polar Series Views
The series of Polar view types are used to display data as a circular graph. These view types are similar to Radar Series Views, but display angles (from 0 to 360 degrees) instead of string values or dates on the angular axis. Note that although these charts normally have a circular shape, they can also be displayed as a polygon. Below is a list of all polar charts currently available in the ASP.NET Chart Control.
