Class RadialAxis

  • All Implemented Interfaces:
    IsLinearAxis, IsNumericAxis

    public class RadialAxis
    extends Axis
    implements IsLinearAxis
    Radial axes are used specifically for the radar and polar area chart types.
    These axes overlay the chart area, rather than being positioned on one of the edges.
    The linear scale is use to chart numerical data.
    As the name suggests, linear interpolation is used to determine where a value lies in relation the center of the axis.
