The point chart can be a polar plot such as the one shown in the following figure.
Each point has two data values: x (angle) and y (radius). Each point is visualized as a point marker.
The point markers in the polar point series or the series can be assigned a border, fill effect, shape, size, and a depth. Assigning null for a border or fill effect indicates that the property is unset. The size of the point marker is measured in model units. The depth of the point marker is measured relative to plot area depth (0 = no depth, 1 = full depth of plot area).
For more information on the point series object in the API, refer to the PolarPointSeries class.
