    public class XYAreaRenderer

extends AbstractXYItemRenderer
implements XYItemRenderer, org.jfree.util.PublicCloneable

Area item renderer for an `XYPlot`. This class can draw (a) shapes at each point, or (b) lines between points, or (c) both shapes and lines, or (d) filled areas, or (e) filled areas and shapes. The example shown here is generated by the `XYAreaRendererDemo1.java` program included in the JFreeChart demo collection:
