Usage

From source file:edu.msu.cme.rdp.classifier.train.validation.distance.BoxPlotUtils.java

public static void createBoxplot(DefaultBoxAndWhiskerCategoryDataset scatterDataset, PrintStream outStream,
        String title, String xAxisLabel, String yAxisLabel, Font lableFont) throws IOException {

    CategoryAxis xAxis = new CategoryAxis(xAxisLabel);

    NumberAxis yAxis = new NumberAxis(yAxisLabel);
    yAxis.setTickLabelFont(lableFont);
    yAxis.setAutoRangeIncludesZero(false);
    yAxis.setRange(0, 100);
    yAxis.setLabelFont(lableFont);

    BoxAndWhiskerRenderer renderer = new BoxAndWhiskerRenderer();
    renderer.setFillBox(true);
    renderer.setBaseLegendTextFont(lableFont);
    renderer.setStroke(new BasicStroke(5.0f));

    CategoryPlot plot = new CategoryPlot(scatterDataset, xAxis, yAxis, renderer);
    JFreeChart boxchart = new JFreeChart(title, new Font("Helvetica", Font.BOLD, 40), plot, true);

    // higher scale factor gives higher resolution
    ChartUtilities.writeScaledChartAsPNG(outStream, boxchart, 800, 1000, 3, 3);
