Class WaterfallPlot

java.lang.Object
  |
  +--gov.sns.tools.chart.WaterfallPlot

All Implemented Interfaces:

java.awt.event.ActionListener, java.util.EventListener

public class WaterfallPlot

extends java.lang.Object

implements java.awt.event.ActionListener

Display the values in a Table column using JClass. The plot is updated when the table values change, and the new values are displayed above the older ones. The values are displayed in a color rendition. This keeps happening until there is no more room in the frame at which point the oldest data (at the bottom) is discarded. The plot is a called waterfall plot.
