<div class="block">A delegate that handles the specification or automatic calculation of the
 interval surrounding the x-values in a dataset.  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).</div>
