public class Graph

extends javax.swing.JPanel

implements java.io.Serializable

Class Graph is the base class for all the graph beans(BarGraph,LineGraph,FilledGraph,MultiLineGraph and MultiBarGraph.) Graph beans are useful to represent the values that are polled from one or more variables of a remote agent. It can be used with bean builders and other applications.
