The Polar series are used to display data as a circular graph. These view types are similar to Radar Series, but display values on the basis of angles (from 0 to 360 degrees). 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.
To learn about other series types that can be plotted together with Polar series, see Series Type Compatibility.
