    public class GraphAccumVisualizer

extends AbstractVisualizer
implements ImageVisualizer, GraphAccumListener, Clearable

This class implements a statistical analyser that plots the accumulated time taken to load each set of pages. The number of plots is equivalent to the number of times the set of pages is configured to load. Created 2001/08/11

Field Detail

### model

    protected transient GraphAccumModel model

### graph

    protected transient GraphAccum graph

### legendPanel

    protected transient JPanel legendPanel

Constructor Detail

### GraphAccumVisualizer

    public GraphAccumVisualizer()

  Constructor.

Method Detail

### 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

### 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`

### getWhiteCanvas

    public Object getWhiteCanvas()

  Returns the panel where labels can be added.

  Returns:
    a panel where labels can be added

### 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()

  Updates the gui to reflect changes.

  Specified by:
    `updateGui` in interface `GraphAccumListener`

### updateGui

    public void updateGui(SampleResult s)

  Updates gui to reflect small changes.

  Specified by:
    `updateGui` in interface `GraphAccumListener`
  Parameters:
    `s` - sample to be added to plot

### clearData

    public void clearData()

  Clear this visualizer data.

  Specified by:
    `clearData` in interface `Clearable`

### toString

    public String toString()

  Returns a description of this instance.

  Overrides:
    `toString` in class `Component`
  Returns:
    description of this instance
