public class HighLowRenderer
extends AbstractXYItemRenderer
implements XYItemRenderer, java.lang.Cloneable, org.jfree.util.PublicCloneable, java.io.Serializable

A renderer that draws high/low/open/close markers on an XYPlot (requires a OHLCDataset). This renderer does not include code to calculate the crosshair point for the plot. The example shown here is generated by the HighLowChartDemo1.java program included in the JFreeChart Demo Collection:
