    public class DistributionGraphVisualizer

extends AbstractVisualizer
implements ImageVisualizer, GraphListener, Clearable

This class implements the visualizer for displaying the distribution graph. Distribution graphs are useful for standard benchmarks and viewing the distribution of data points. Results tend to clump together. Created May 25, 2004

Constructor Detail

### DistributionGraphVisualizer

    public DistributionGraphVisualizer()

  Constructor for the GraphVisualizer object.

Method Detail

### getImage

    public Image getImage()

  Gets the Image attribute of the GraphVisualizer object.

  Specified by:
    `getImage` in interface `ImageVisualizer`
  Returns:
    the Image value

### updateGui

    public void updateGui()

  Specified by:
    `updateGui` in interface `GraphListener`

### updateGui

    public void updateGui(Sample s)

  Specified by:
    `updateGui` in interface `GraphListener`

### add

    public void add(SampleResult res)

  Description copied from interface: `Visualizer`
  This method is called by sampling thread to inform the visualizer about the arrival of a new sample.

  Specified by:
    `add` in interface `Visualizer`

### getLabelResource

    public String getLabelResource()

  Description copied from interface: `JMeterGUIComponent`
  Get the component's resource name, which getStaticLabel uses to derive the component's label in the local language. The resource name is fixed, and does not vary with the selected language. Normally this method should be overriden in preference to overriding getStaticLabel(). However where the resource name is not available or required, getStaticLabel() may be overridden instead.

  Specified by:
    `getLabelResource` in interface `JMeterGUIComponent`
  Returns:
    the resource name

### clearData

    public void clearData()

  Description copied from interface: `Clearable`
  Clears the current data of the object.

  Specified by:
    `clearData` in interface `Clearable`

### toString

    public String toString()

  Overrides:
    `toString` in class `Component`

### getPrintableComponent

    public JComponent getPrintableComponent()

  Method implements Printable, which is suppose to return the correct internal component. The Action class can then print or save the graphics to a file.

  Specified by:
    `getPrintableComponent` in interface `Printable`
  Overrides:
    `getPrintableComponent` in class `AbstractJMeterGuiComponent`
  Returns:
    this object
