Class PNI

java.lang.Object
  extended by jhplot.PNI
All Implemented Interfaces:
java.io.Serializable

public class PNI
extends java.lang.Object
implements java.io.Serializable

/** A container to hold data points in many dimensions. All numbers are expected to be integers. It extends ArrayList and adds many new features for data manipulation. The class does not have graphical option (use H1D to show the data or methods of this class which transform P0D to a H1D histogram).
