@Override
public void mouseClicked(final MouseEvent event) {

    // Let the parent handle the event (selection etc.)
    super.mouseClicked(event);

    if (event.getX() < 70) { // User clicked on Y-axis
        if (event.getClickCount() == 2) { // Reset zoom on Y-axis
            XYDataset data = ((XYPlot) getChart().getPlot()).getDataset();
            Number maximum = DatasetUtils.findMaximumRangeValue(data);
            getXYPlot().getRangeAxis().setRange(0, 1.05 * maximum.floatValue());
        } else if (event.getClickCount() == 1) {
