I used a code in order to display a graph. I want to insert a button in this graph (Show details) that i will used in order to present some details about the graph .It is realisable? thanks.

if(jCheckBox3.isSelected()) {
    try {
        con = getConnection("jdbc:mysql://localhost:3306/base_rapport","root","");
        Statement statement = con.createStatement(rs.TYPE_FORWARD_ONLY,rs.CONCUR_READ_ONLY);
        String sql3 = "Select Vendor, sum(Rate) as Rate from (select case Vendor when 'NSN' then 'Nokia' else Vendor end as Vendor, Rate from  (  Select vendor ,(count(1) )*100/(Select count(id_incident)from incident where open_time between '"+jTextField1.getText()+"' and'"+jTextField2.getText()+"' and vendor !='') as Rate  from incident   where open_time between '"+jTextField1.getText()+"'and'"+jTextField2.getText()+"' and vendor !='' group by upper(vendor) ) as x ) as y group by vendor";

        rs3 = statement.executeQuery(sql3);
        DefaultPieDataset pieDataset = new DefaultPieDataset(); 

        while(rs3.next()) {      
            pieDataset.setValue( rs3.getString("vendor"),rs3.getDouble(2));
        }

        JFreeChart chart = ChartFactory.createPieChart3D("Disfonctionnement par fournisseurs",  pieDataset, true, true, true); 
        PiePlot3D piePlot3d = (PiePlot3D) chart.getPlot();
        piePlot3d.setLabelGenerator(new StandardPieSectionLabelGenerator("{0}={1}"));
        fenetre fen3 = new fenetre();
        JPanel pnl = new JPanel(new BorderLayout()); 

        fen3.setContentPane(pnl); 
        fen3.setVisible(true);
        fen3.setSize(500, 500); 
        ChartPanel cPanel1 = new ChartPanel(chart);    
        pnl.add(cPanel1);
        File fichier = new File("C:\\Users\\alaeddine.zammeli.st\\Desktop\\résultat_application\\Répartition par fournisseur de '"+jTextField1.getText()+"' à '"+jTextField2.getText()+"'.png");

        try { 
            ChartUtilities.saveChartAsPNG(fichier, chart, 500, 500); 
        } catch (IOException e) { 
            e.printStackTrace(); 
        } 
    } catch (Exception e) {
        JOptionPane.showMessageDialog(this,e);
    }
}

推荐答案

a ChartMouseListener 到包含图表的 ChartPanel 。您可以获得有关点击的 PieSectionEntity 的详细信息，如下所示。请参阅 toString（）在 PieSectionEntity 中的实现。您也可以选择突出显示此处所示的实体。

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) {
    }
});
