Examples of org.jfree.chart.renderer.xy.CandlestickRenderer

org.jfree.chart.renderer.xy.CandlestickRenderer
A renderer that draws candlesticks on an {@link XYPlot} (requires a{@link 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.


    configureChart(jfreeChart);


    XYPlot xyPlot = (XYPlot) jfreeChart.getPlot();
    JRCandlestickPlot candlestickPlot = (JRCandlestickPlot)getPlot();
    CandlestickRenderer candlestickRenderer = (CandlestickRenderer) xyPlot.getRenderer();
    boolean isShowVolume = candlestickPlot.getShowVolume() == null ? true : candlestickPlot.getShowVolume().booleanValue();
    candlestickRenderer.setDrawVolume(isShowVolume);


    // Handle the axis formating for the category axis
    configureAxis(xyPlot.getDomainAxis(), candlestickPlot.getTimeAxisLabelFont(),
        candlestickPlot.getTimeAxisLabelColor(), candlestickPlot.getTimeAxisTickLabelFont(),
        candlestickPlot.getTimeAxisTickLabelColor(), candlestickPlot.getTimeAxisTickLabelMask(), candlestickPlot.getTimeAxisVerticalTickLabels(),
