Class AggregatedRange

java.lang.Object
  com.jidesoft.range.AggregatedRange

All Implemented Interfaces:

Range<Double>

public class AggregatedRange
extends Object
implements Range<Double>

A range class formed from a collection of Positionable instances. The class can be used to derive the minimum and maximum values for the collection of Positionables, as well as providing other useful information such as the sum of all the positive values and the sum of all the negative values. (These are used in the preparation of a stacked bar chart.)
