public Double RadiusIncrement {get; set;}
Remarks
RadiusIncrement is the same as accessing the Chart.Axes.Left.Increment property when using Polar series.
It determines the increment, in polar radius scales, used to draw the ring grid lines. You can find the property in the Polar series page of the editor
You can use RadiusIncrement with Polar series .AngleIncrement to control how gridlines are displayed in Polar charts.
