```
public void drawBackgroundImage(Graphics2D g2,
                                Rectangle2D area)
```
    Draws the background image (if there is one) aligned within the specified area.
    
    Parameters:
    
    g2 - the graphics device.
    
    area - the area.

  - drawOutline
```
public void drawOutline(Graphics2D g2,
                        Rectangle2D area)
```
    Draws the plot outline. This method will be called during the chart drawing process and is declared public so that it can be accessed by the renderers used by certain subclasses. You shouldn't need to call this method directly.
    
    Parameters:
    
    g2 - the graphics device.
    
    area - the area within which the plot should be drawn.
  - handleClick
```
public void handleClick(int x,
                        int y,
                        PlotRenderingInfo info)
```
    Handles a 'click' on the plot. Since the plot does not maintain any information about where it has been drawn, the plot rendering info is supplied as an argument so that the plot dimensions can be determined.
    
    Parameters:
    
    x - the x coordinate (in Java2D space).
    
    y - the y coordinate (in Java2D space).
    
    info - an object containing information about the dimensions of the plot.
  - zoom
```
public void zoom(double percent)
```
    Performs a zoom on the plot. Subclasses should override if zooming is appropriate for the type of plot.
    
    Parameters:
    
    percent - the zoom percentage.
  - annotationChanged
```
public void annotationChanged(AnnotationChangeEvent event)
```
    Receives notification of a change to an Annotation added to this plot.
    
    Specified by:
    
    annotationChanged in interface AnnotationChangeListener
    
    Parameters:
    
    event - information about the event (not used here).
    
    Since:
    
    1.0.14
  - axisChanged
```
public void axisChanged(AxisChangeEvent event)
```
    Receives notification of a change to one of the plot's axes.
    
    Specified by:
    
    axisChanged in interface AxisChangeListener
    
    Parameters:
    
    event - information about the event (not used here).
  - datasetChanged
```
public void datasetChanged(DatasetChangeEvent event)
```
    Receives notification of a change to the plot's dataset.
    The plot reacts by passing on a plot change event to all registered listeners.
    
    Specified by:
    
    datasetChanged in interface DatasetChangeListener
    
    Parameters:
    
    event - information about the event (not used here).
  - markerChanged
```
public void markerChanged(MarkerChangeEvent event)
```
    Receives notification of a change to a marker that is assigned to the plot.
    
    Specified by:
    
    markerChanged in interface MarkerChangeListener
    
    Parameters:
    
    event - the event.
    
    Since:
    
    1.0.3
  - equals
```
public boolean equals(Object obj)
```
    Tests this plot for equality with another object.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object (null permitted).
    
    Returns:
    
    true or false.
  - clone
```
public Object clone()
             throws CloneNotSupportedException
```
    Creates a clone of the plot.
    
    Specified by:
    
    clone in interface org.jfree.util.PublicCloneable
    
    Overrides:
    
    clone in class Object
    
    Returns:
    
    A clone.
    
    Throws:
    
    CloneNotSupportedException - if some component of the plot does not support cloning.
  - resolveDomainAxisLocation
```
public static org.jfree.ui.RectangleEdge resolveDomainAxisLocation(AxisLocation location,
                                                                   PlotOrientation orientation)
```
    Resolves a domain axis location for a given plot orientation.
    
    Parameters:
    
    location - the location (null not permitted).
    
    orientation - the orientation (null not permitted).
    
    Returns:
    
    The edge (never null).
  - resolveRangeAxisLocation
```
public static org.jfree.ui.RectangleEdge resolveRangeAxisLocation(AxisLocation location,
                                                                  PlotOrientation orientation)
```
    Resolves a range axis location for a given plot orientation.
    
    Parameters:
    
    location - the location (null not permitted).
    
    orientation - the orientation (null not permitted).
    
    Returns:
    
    The edge (never null).
