                         PlotRenderingInfo info,
                         Point2D source)
```
    Pans the range axes by the specified percentage.
    
    Specified by:
    
    panRangeAxes in interface Pannable
    
    Parameters:
    
    percent - the distance to pan (as a percentage of the axis length).
    
    info - the plot info
    
    source - the source point where the pan action started.
    
    Since:
    
    1.0.13
  - equals
```
public boolean equals(Object obj)
```
    Tests an arbitrary object for equality with this plot. Note that FastScatterPlot carries its data around with it (rather than referencing a dataset), and the data is included in the equality test.
    
    Overrides:
    
    equals in class Plot
    
    Parameters:
    
    obj - the object (null permitted).
    
    Returns:
    
    A boolean.
  - clone
```
public Object clone()
             throws CloneNotSupportedException
```
    Returns a clone of the plot.
    
    Specified by:
    
    clone in interface org.jfree.util.PublicCloneable
    
    Overrides:
    
    clone in class Plot
    
    Returns:
    
    A clone.
    
    Throws:
    
    CloneNotSupportedException - if some component of the plot does not support cloning.
