public class CandlestickRenderer
extends AbstractXYItemRenderer
implements XYItemRenderer, Cloneable, org.jfree.util.PublicCloneable, Serializable
```
A renderer that draws candlesticks on an XYPlot (requires a OHLCDataset). The example shown here is generated by the CandlestickChartDemo1.java program included in the JFreeChart demo collection:

This renderer does not include code to calculate the crosshair point for the plot.
