Class Axis

  • Direct Known Subclasses:
    CartesianAxis, ProjectionAxis, RadialAxis
    public abstract class Axis
extends Object
    Axes are an integral part of a chart.
    They are used to determine how data maps to a pixel value on the chart.
    It contains a number of config callbacks that can be used to change parameters in the scale at different points in the update process.
