使用 JPanel 将 ChartPanel 添加到 JTabbedPane [英] Adding ChartPanel to JTabbedPane using JPanel

问题描述

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 个标签.

I want to add JFreeChart to JPanel and then add JPanel to JTabbedPane. I managed to display JFreeChart on JFrame, but I want to add JFreeChart as a 4th tab of 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));

  }

要添加到 TabbedPane 的代码:

Code to add to TabbedPane:

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

推荐答案

如图 如何使用选项卡式窗格，您可以将组件添加到选项卡式窗格中.ChartPanel，JPanel 的子类，就是这样一个组件.除了这些示例之外，您还可以使用下面的示例以试验其他功能.

As shown in How to Use Tabbed Panes, you can add components to a tabbed pane. ChartPanel, a subclass of JPanel, is such a component. In addition to these examples, you can use the example below to experiment with other features.

由于您是新手，限制使用 NetBeans GUI 编辑器，在您的问题中暗示，但继续使用 NetBeansIDE.

As you are new, limit using the NetBeans GUI editor, implied in your question, but continue to use the NetBeans IDE.
