This is used to extend a regular <A HREF="../../../../org/jfree/data/xy/XYDataset.html" title="interface in org.jfree.data.xy"><CODE>XYDataset</CODE></A> to support the <A HREF="../../../../org/jfree/data/xy/IntervalXYDataset.html" title="interface in org.jfree.data.xy"><CODE>IntervalXYDataset</CODE></A> interface. <p> The decorator pattern was not used because of the several possibly implemented interfaces of the decorated instance (e.g. <A HREF="../../../../org/jfree/data/xy/TableXYDataset.html" title="interface in org.jfree.data.xy"><CODE>TableXYDataset</CODE></A>, <A HREF="../../../../org/jfree/data/RangeInfo.html" title="interface in org.jfree.data"><CODE>RangeInfo</CODE></A>, <A HREF="../../../../org/jfree/data/DomainInfo.html" title="interface in org.jfree.data"><CODE>DomainInfo</CODE></A> etc.). <p> The width can be set manually or calculated automatically. The switch autoWidth allows to determine which behavior is used. The auto width calculation tries to find the smallest gap between two x-values in the dataset. If there is only one item in the series, the auto width calculation fails and falls back on the manually set interval width (which is itself defaulted to 1.0).<P><P><DL><DT><B>Author:</B></DT>
