Package org.pepstock.charba.client.geo

Class SizeAxis

  • All Implemented Interfaces:
    IsLinearAxis, IsNumericAxis
    public final class SizeAxis
extends CartesianLinearAxis
    The scale is used to map the values to symbol radius size.
    Provides the elements, as colored legend, which can provide the how the values are distributed on map.
