SharePoint Chart Ordinal Scale

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.

Consistent Increments
Choose consistent and meaningful increments for the angular scale (e.g., 30-degree increments for monthly data).

Labeling
Ensure labels are clearly readable and not overlapping, by using the automatic label overlap resolve layout of the scale.
