Source Link

Document

Creates a new renderer with the specified precision and specified fill of the area 'under' (between '0' and) the spline.

Usage

From source file:inflor.core.plots.HistogramPlot.java

@Override
public JFreeChart createChart(FCSFrame dataFrame, TransformSet transforms) {

    Optional<FCSDimension> domainDimension = FCSUtilities.findCompatibleDimension(dataFrame,
            spec.getDomainAxisName());//from   w w  w  . ja v a 2  s . co  m

    AbstractTransform transform = transforms.get(domainDimension.get().getShortName());
    double[] transformedData = transform.transform(domainDimension.get().getData());

    Histogram1D hist = new Histogram1D(transformedData, transform.getMinTranformedValue(),
            transform.getMaxTransformedValue(), ChartingDefaults.BIN_COUNT);

    DefaultXYDataset dataset = new DefaultXYDataset();
    dataset.addSeries(dataFrame.getDisplayName(), hist.getData());

    ValueAxis domainAxis = PlotUtils.createAxis(domainDimension.get().getDisplayName(), transform);
    ValueAxis rangeAxis = new NumberAxis(spec.getRangeAxisName());
    FillType fillType = FillType.TO_ZERO;
    XYItemRenderer renderer = new XYSplineRenderer(1, fillType);
    renderer.setSeriesShape(0, ShapeUtilities.createDiamond(Float.MIN_VALUE));// Make the points
                                                                              // invisible
    XYPlot plot = new XYPlot(dataset, domainAxis, rangeAxis, renderer);
    return new JFreeChart(plot);
