Class DistributionGraph

    java.lang.Object
      java.awt.Component
          java.awt.Container
              javax.swing.JComponent
                  org.apache.jmeter.visualizers.DistributionGraph

All Implemented Interfaces:
  Clearable, ImageObserver, MenuContainer, Scrollable, Serializable

public class DistributionGraph
extends JComponent
implements Scrollable, Clearable

New graph for drawing distribution graph of the results. It is intended as a way to view the data after the stress has been performed. Although it can be used at runtime, it is not recommended, since it is rather intensive. The graph will draw a red line at 90% and an orange line at 50%. I like distribution graphs because they allow me to see how the data clumps. In general, the data will tend to clump in predictable ways when the application is well designed and implemented. Data that generates erratic graphs are generally not desirable.
