Returns the maximum domain value for the specified dataset.

Usage

From source file:dbseer.gui.events.InformationChartMouseListener.java

@Override
public void chartMouseClicked(ChartMouseEvent event) {
    Rectangle2D dataArea = chartPanel.getScreenDataArea();
    JFreeChart chart = event.getChart();
    XYPlot plot = (XYPlot) chart.getPlot();
    ValueAxis xAxis = plot.getDomainAxis();
    int x = (int) Math.round(xAxis.java2DToValue(event.getTrigger().getX(), dataArea, RectangleEdge.BOTTOM));

    XYDataset dataset = plot.getDataset();
    int maxX = DatasetUtilities.findMaximumDomainValue(dataset).intValue();
    if (x >= 1 && x <= maxX) {
        int seriesCount = dataset.getSeriesCount();
        int[] mixtures = new int[seriesCount - 1];
        int total = 0;
        for (int i = 0; i < seriesCount - 1; ++i) {
            mixtures[i] = (int) dataset.getYValue(i, x - 1);
            total += mixtures[i];//from   ww w. j a va 2s. c om
        }
        for (int i = 0; i < seriesCount - 1; ++i) {
            mixtures[i] = (int) Math.round((double) mixtures[i] / (double) total * 100.0);
            tpsMixturePanel.setMixture(i, mixtures[i]);
        }
    }
}
