        this.underlying.addChangeListener(this);

 public Object clone() throws CloneNotSupportedException 
{
        XYBarDataset clone = (XYBarDataset) super.clone();

Returns an independent copy of the dataset. Note that:
• the underlying dataset is only cloned if it implements the PublicCloneable interface;
• the listeners registered with this dataset are not carried over to the cloned dataset.
