<DL>
<DD>Sets the maximum number of items that will be retained in the series.  
 If you add a new item to the series such that the number of items will 
 exceed the maximum item count, then the first element in the series is 
 automatically removed, ensuring that the maximum item count is not 
 exceeded.
 <p>
 Typically this value is set before the series is populated with data,
 but if it is applied later, it may cause some items to be removed from
 the series (in which case a <A HREF="../../../../org/jfree/data/general/SeriesChangeEvent.html" title="class in org.jfree.data.general"><CODE>SeriesChangeEvent</CODE></A> will be sent to
 all registered listeners.
