public class Test {
    public static void main(String [] args){
        JFrame frame = new JFrame();
        frame.setSize(new Dimension(400,500));
        frame.setLocation(10,10);

        frame.setLayout(new FlowLayout());
        JPanel p1=new JPanel();
        JPanel p2=new JPanel();
        //把Jbutton替换为你的饼图应该就可以了。
        JButton  b1=new JButton("JPanel1");
        JButton  b2=new JButton("JPanel2");
        p1.add(b1);
        p2.add(b2);

        frame.add(p2, FlowLayout.CENTER);

        //在设置frame为显示状态
        frame.setVisible(true);
    }
}

这想法确实很不错，但是我要加对象不是简单的Button，而是JFreeChart，把JFreeChart加到JPanel中，解决这个你就答全了。

呵呵……不好意思，我这里没有JFreeChart的jar包，无法继续做了。不过如果你能让一个饼图出来，两个也是一样的。

嗯嗯..饼图早上8点就出来了，但是现在停留在一个JFrame怎么可以显示出2个饼图，尝试用2个Jpanel分别装图。
以下是实现一个饼显示出来的。PieDataset dataset = createDataset();//调用createDataset()方法，返回DefaultPieDataset对象
JFreeChart chart = createChart(dataset, chartTitle);//调用createDataset()方法，返回JFreeChart对象
ChartPanel chartPanel = new ChartPanel(chart);//一个Swing GUI component，用来显示JFreeChart
chartPanel.setPreferredSize(new java.awt.Dimension(210, 280));//设置组件尺寸
setContentPane(chartPanel);//设置 chartPanel 属性。此方法由构造方法调用。如果用Jpanel的话，那就要替代ChartPanel
那就要把JFreeChart chart 放到Jpanel中，能解决这个问题我就成功了，各位还有什么好的见解吗？

        frame.setLayout(new FlowLayout());
        JPanel p1=new JPanel();
        JPanel p2=new JPanel();
        //把Jbutton替换为你的饼图应该就可以了。
        //JButton  b1=new JButton("JPanel1");
        //饼图1
        JFreeChart chart = createChart(createDataset());
       // JButton  b2=new JButton("JPanel2");
        ChartPanel localChartPanel = new ChartPanel(chart, false);

        return dataset;
    }
    /**

     *
     * @param dataset  the dataset.
     *
     * @return A chart.
     */
    private static JFreeChart createChart(PieDataset dataset) {

        JFreeChart chart = ChartFactory.createPieChart(
            "Pie Chart Demo 1",  // chart title
            dataset,             // data
            true,               // include legend
            true,
            false
        );        PiePlot plot = (PiePlot) chart.getPlot();
        plot.setSectionOutlinesVisible(false);
        plot.setLabelFont(new Font("SansSerif", Font.PLAIN, 12));
        plot.setNoDataMessage("No data available");
        plot.setCircular(false);
        plot.setLabelGap(0.02);
        return chart;

    }

}

其实思路就和上面是一样的。ChartPanel的父类就是JPanel。和JButton一样都是Component对象
面板里面是可以嵌套面板的。希望对你有帮助。上面的例子是可以直接跑起来的。
