Public Property LogarithmicBase As Double

Property Value

Type Description

A Double value which is the logarithmic base.


If a chart's series have their Series.ValueScaleType property set to ScaleType.Numerical, you can use the CircularAxisY2D.Logarithmic property to specify whether the logarithmic scale should be used to display axis values. When it is set to true, it is possible to define a logarithmic base value via the LogarithmicBase property.

Via the LogarithmicBase property, you can define a base value as a logarithm, which will be used to calculate the axis values.

The following images demonstrate how the LogarithmicBase property works.

LogarithmicBase = 10 LogarithmicBase = 20
CircularAxisY -  Logarithmic - True CircularAxisY - LogarithmicBase - 20
