#JAVA实现在面板中添加图表

这篇博客探讨了如何在使用Java和JFreeChart创建的饼状图中插入一个按钮，以便显示图形相关详细信息的方法。通过连接数据库获取数据，利用DefaultPieDataset和PieChart3D创建图表，并尝试在图表面板上添加组件展示更多信息。

我使用了代码来显示图形.

我想在此图中插入一个按钮(显示详细信息),以显示有关该图形的一些详细信息.可以实现吗？

谢谢.

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);

}
