Answer 1

Add a ChartMouseListener to the ChartPanel that contains your chart. You can get details about the PieSectionEntity that was clicked as shown below. See the implementation of toString() in PieSectionEntity for more. Optionally, you can highlight the entity as shown here.

ChartPanel panel = new ChartPanel(chart);
panel.addChartMouseListener(new ChartMouseListener() {

    @Override
    public void chartMouseClicked(ChartMouseEvent e) {
        ChartEntity entity = e.getEntity();
        if (entity instanceof PieSectionEntity) {
            PieSectionEntity pse = (PieSectionEntity) entity;
            System.out.println(pse);
        }
    }

    @Override
    public void chartMouseMoved(ChartMouseEvent event) {
    }
});
