使用JPanel将ChartPanel添加到JTabbedPane

Question

我要添加JFreeChart到JPanel，然后添加JPanel到JTabbedPane。我设法显示JFreeChart上JFrame，但我想添加JFreeChart为一个4片JTabbedPane。

显示图表的代码：

public class Chart extends javax.swing.JPanel {

  private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

        JPanel jPanel1 = new JPanel();

        DefaultCategoryDataset dataset = new DefaultCategoryDataset();

        dataset.setValue(60, "Marks", "Student 1");

        dataset.setValue(40, "Marks", "Student 2");

        dataset.setValue(90, "Marks", "Student 3");

        dataset.setValue(50, "Marks", "Student 4");

        dataset.setValue(70, "Marks", "Student 5");

        dataset.setValue(30, "Marks", "Student 6");

        JFreeChart chart = ChartFactory.createBarChart(

            "Student Marks", "Student Name", "Marks", dataset,

            PlotOrientation.VERTICAL, false, true, false);

        CategoryPlot p = chart.getCategoryPlot();

        p.setRangeGridlinePaint(Color.BLACK);

        ChartPanel panel = new ChartPanel(chart);

        panel.setDomainZoomable(true);

        jPanel1.add(panel, BorderLayout.CENTER);

        panel.setPreferredSize(new java.awt.Dimension(500, 270));

  }

添加到TabbedPane的代码：

tabStoreTrans.add("chart", new Chart());
