org.jfree.data.Series

org.jfree.data.MatrixSeries

org.jfree.data.NormalizedMatrixSeries

All Implemented Interfaces:

Serializable, Cloneable

public class NormalizedMatrixSeries
extends MatrixSeries

Represents a dense normalized matrix M[i,j] where each Mij item of the matrix has a value (default is 0). When a matrix item is observed using getItem method, it is normalized, that is, divided by the total sum of all items. It can be also be scaled by setting a scale factor.
