    public class StatisticalBarRenderer

extends BarRenderer
implements CategoryItemRenderer, java.lang.Cloneable, org.jfree.util.PublicCloneable, java.io.Serializable

A renderer that handles the drawing a bar plot where each bar has a mean value and a standard deviation line. The example shown here is generated by the `StatisticalBarChartDemo1.java` program included in the JFreeChart Demo Collection:
