使用JPanel将ChartPanel添加到JTabbedPane

我想将JFreeChart添加到JPanel ，然后将JPanel添加到JTabbedPane 。 我设法在JFrame上显示JFreeChart ，但我想添加JFreeChart作为JTabbedPane的第4个选项卡。

代码显示图表：

 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)); } 

要添加到TabbedPane的代码：

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

如“ 如何使用选项卡式窗格”所示 ，您可以将组件添加到选项卡式窗格中。 ChartPanel是JPanel一个子类，就是这样一个组件。 除了这些例子 ，您可以使用下面的例子来试验其他function。

由于您是新手，因此应限制使用NetBeans GUI编辑器，这意味着您的问题，但是继续使用NetBeans IDE。
