Usage

From source file:classpackage.ChartGalaxy.java

private static JFreeChart createChart(final XYDataset dataset) {
    JFreeChart jfreechart = ChartFactory.createScatterPlot("MDS Galaxy", "X", "Y", createDataset(),
            PlotOrientation.VERTICAL, true, true, false);
    XYPlot xyPlot = (XYPlot) jfreechart.getPlot();
    XYItemRenderer renderer = xyPlot.getRenderer();
    renderer.setBaseItemLabelGenerator(new LabelGenerator());
    renderer.setBaseItemLabelPaint(Color.WHITE);//label
    renderer.setBasePositiveItemLabelPosition(new ItemLabelPosition(ItemLabelAnchor.CENTER, TextAnchor.CENTER));
    renderer.setBaseItemLabelFont(renderer.getBaseItemLabelFont().deriveFont(15f));
    renderer.setBaseItemLabelsVisible(true);
    renderer.setBaseToolTipGenerator(new StandardXYToolTipGenerator());

    //set false para linhas no grafico
    xyPlot.setDomainGridlinesVisible(false);
    xyPlot.setRangeGridlinesVisible(false);

    double size = 40.0;
    double delta = size / 2.0;

    renderer.setSeriesShape(0, shape);/*from www  . j av  a  2  s .  co m*/
