Question

我已经尝试过寻找答案让这个工作但是没有设法这样做我想要失去理智，所以这就是我的问题。

我最近下载了JFreeChart来创建图表并在我的GUI中实现它们。这是我想要插入图形的GUI和面板（标记为白色）：

我使用NetBeans编辑器构建GUI和在线提供的JFreeChart示例。以下是我的GUI代码：

import java.awt.Color;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.math.BigDecimal;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.SwingConstants;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.DefaultTableModel;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PiePlot3D;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.data.general.PieDataset;
import org.jfree.util.Rotation;


public class Report extends JFrame implements Defaults {


public MMap j1map,j2map,j3map;
public int total_stations = 0, total_jobs = 0, total_parts = 0;
BigDecimal[] j1_systimebig, j1_worktimebig, j1_idletimebig, j1_queuetimebig,
             j2_systimebig, j2_worktimebig, j2_idletimebig, j2_queuetimebig,
             j3_systimebig, j3_worktimebig, j3_idletimebig, j3_queuetimebig;
public String sim_time;
BigDecimal systime = new BigDecimal(0);
BigDecimal worktime = new BigDecimal(0);
BigDecimal idletime = new BigDecimal(0);
BigDecimal queuetime = new BigDecimal(0);
/**
 * Creates new form Report
 */
public Report() {
    //setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setTitle(TITLE_Report);
    validate();
    setResizable(false);
    setVisible(true);
    //setLocationRelativeTo(null);
    initComponents();
    this.addWindowListener(new WindowAdapter() {
        @Override
       public void windowClosing(WindowEvent e) {
          e.getWindow().dispose();
          }
       }
    );
    centertables();
    //JLayeredPane layeredPane = new JLayeredPane(); 
    PieChart demo = new PieChart("Which operating system are you using?");
    demo.setOpaque(true); 
    demo.setBounds(0, 0, 300, 300);
    demo.setFocusable(true);
    demo.setBackground(Color.gray); 
    demo.setBorder(BorderFactory.createLineBorder(Color.black, 1));
    //start();
    demo.setDoubleBuffered(true);        
    //demo.pack();
    //demo.setVisible(true);        
    //PieChart("teste");
    chartPanel1.add(demo, new Integer(0));
    //layeredPane.add(demo, new Integer(0));
    //this.getContentPane().add(jLayeredPane1); 
}

/* *************************************
 *          GRAPHICS
 *************************************/

public void PieChart(String chartTitle) {
    System.out.println("PieChart");
    // This will create the dataset 
    PieDataset dataset = createDataset();
    // based on the dataset we create the chart
    JFreeChart chart = createChart(dataset, chartTitle);
    // we put the chart into a panel
    ChartPanel chartPanel = new ChartPanel(chart);
    // default size
    chartPanel.setPreferredSize(new java.awt.Dimension(250, 270));
    // add it to our application
    //setContentPane(chartPanel);
    //StationsPanelGraph.add(chartPanel);
    //jLayeredPane1.add(chartPanel, new Integer(0), 0);

}

private  PieDataset createDataset() {
    System.out.println("PieDataset");
    DefaultPieDataset result = new DefaultPieDataset();
    result.setValue("Linux", 29);
    result.setValue("Mac", 20);
    result.setValue("Windows", 51);
    return result;

}

private JFreeChart createChart(PieDataset dataset, String title) {
    System.out.println("Create Chart");
    JFreeChart chart = ChartFactory.createPieChart3D(title,          // chart title
        dataset,                // data
        true,                   // include legend
        true,
        false);

    PiePlot3D plot = (PiePlot3D) chart.getPlot();
    plot.setStartAngle(290);
    plot.setDirection(Rotation.CLOCKWISE);
    plot.setForegroundAlpha(0.5f);
    return chart;

}    

 /* *************************************
 *         END GRAPHICS
 *************************************/  

}

这就是结果：

我正在初始化并在主类构造函数中添加图表，下面是图表的代码。我必须避免发布整个代码，因为它超出了字符限制，但是这里是完整代码的URL（通过NetBeans初始化Swing组件）：http://tny.cz/8a4e8b2f

有任何解决方案的提示吗？

提前谢谢并告诉我是否还需要其他任何东西。

不要让GUI设计师决定你的设计。如果有的话，使用它来管理单个面板，如建议here。没有.form文件就无法编辑GUI项目;我刚刚使用FlowLayout添加了您的图表，因此您可以在不改变initComponents()的情况下看到它。

import java.awt.FlowLayout;
import java.math.BigDecimal;
import javax.swing.JFrame;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PiePlot3D;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.data.general.PieDataset;
import org.jfree.util.Rotation;

public class Report extends JFrame {

    public int total_stations = 0, total_jobs = 0, total_parts = 0;
    BigDecimal[] j1_systimebig, j1_worktimebig, j1_idletimebig, j1_queuetimebig,
        j2_systimebig, j2_worktimebig, j2_idletimebig, j2_queuetimebig,
        j3_systimebig, j3_worktimebig, j3_idletimebig, j3_queuetimebig;
    public String sim_time;
    BigDecimal systime = new BigDecimal(0);
    BigDecimal worktime = new BigDecimal(0);
    BigDecimal idletime = new BigDecimal(0);
    BigDecimal queuetime = new BigDecimal(0);

    private static final String title = "Which operating system are you using?";

    /**
    * Creates new form Report
    */
    public Report() {
        initComponents();
        jPanel2.removeAll();
        jPanel2.setLayout(new FlowLayout(FlowLayout.LEFT));
        jPanel2.add(createPieChart(title));
        this.setLocationRelativeTo(null);
    }

    private ChartPanel createPieChart(String chartTitle) {
        System.out.println("PieChart");

        ChartPanel chartPanel = new ChartPanel(chart);
        return chartPanel;
    }

    private PieDataset createDataset() {

    }

        PiePlot3D plot = (PiePlot3D) chart.getPlot();
        plot.setStartAngle(290);
        plot.setDirection(Rotation.CLOCKWISE);
        plot.setForegroundAlpha(0.5f);
