使用JFreeChart做曲线图和table表格，要求图和表格不是重合的

要在曲线图下面加一个JSP页面table那样的表格(但是不允许用JSP页面要在JFreeChart中实现表格),然后table每行显示每条曲线对应的数据,每个单元格对应一条线的一个节点，上面是曲线图，然后下面紧跟着table表格，看了下官网的源代码，他里面好像用的是JTable来画的，但是不知道怎么把创建好的曲线图JFreeChart对象和JTable都放到一个板块上，也不知道JFreeChart里面哪个类可以提供直接来画Table那样的,哪个高手知道啊？？？ 下面是我弄好的曲线图，然后怎么在曲线图下面再添加一个table表格

jfreechart本来就有一个类，ChartPanel，其实该类也是继承JPanel的，所以你满可以把它作为一个普通的jpanel对待，和你的JTable所在的面板JScrollPane,共同放在一个JPanel,或是一个JFrame中，对其布局进行设置。

楼主可以参考一下代码（文档时需要付费的）：

        JTable table = new JTable(this.model);
        TableCellRenderer renderer1 = new DateCellRenderer(
                new SimpleDateFormat("HH:mm:ss"));
        TableCellRenderer renderer2 = new NumberCellRenderer();
        table.getColumnModel().getColumn(1).setCellRenderer(renderer1);
        table.getColumnModel().getColumn(2).setCellRenderer(renderer2);
        table.getColumnModel().getColumn(3).setCellRenderer(renderer1);
        table.getColumnModel().getColumn(4).setCellRenderer(renderer2);
        table.getColumnModel().getColumn(5).setCellRenderer(renderer1);
        table.getColumnModel().getColumn(6).setCellRenderer(renderer2);
        dashboard.add(new JScrollPane(table));
        content.add(dashboard, BorderLayout.SOUTH);
        add(content);

    }[/code]

上面的这段代码你看到了吗，是一个内部类，该类继承了Jpanel,就是说可以往上面放组件，你注意代码中
[code="java"]JFreeChart chart = createChart();
this.chartPanel = new ChartPanel(chart);
this.chartPanel.setPreferredSize(new java.awt.Dimension(600, 270));
this.chartPanel.setDomainZoomable(true);
this.chartPanel.setRangeZoomable(true);
Border border = BorderFactory.createCompoundBorder(BorderFactory
.createEmptyBorder(4, 4, 4, 4), BorderFactory
.createEtchedBorder());
this.chartPanel.setBorder(border);
content.add(this.chartPanel);[/code]

上面代码首先会创建chart,然后将生成的参数传递给ChartPanel，其实这个也是继承了Jpanel,然后，[color=red]this.chartPanel = new ChartPanel(chart);[/color]
接着后面的代码是设置一些大小，然后，content.add(this.chartPanel);明白了吧；

就是说生成的jFreehart作为参数传递给了一个面板，然后设置这个面板的大小，然后将设置好的面板，放到一个另外一个面板A上，而面板A就是最下层的面板。

继续往下看
[code="java"]JTable table = new JTable(this.model);
TableCellRenderer renderer1 = new DateCellRenderer(
new SimpleDateFormat("HH:mm:ss"));
TableCellRenderer renderer2 = new NumberCellRenderer();
table.getColumnModel().getColumn(1).setCellRenderer(renderer1);
table.getColumnModel().getColumn(2).setCellRenderer(renderer2);
table.getColumnModel().getColumn(3).setCellRenderer(renderer1);
table.getColumnModel().getColumn(4).setCellRenderer(renderer2);
table.getColumnModel().getColumn(5).setCellRenderer(renderer1);
table.getColumnModel().getColumn(6).setCellRenderer(renderer2);
dashboard.add(new JScrollPane(table));[/code]

这部分就是生成你想要的table，然后将table放到JScrollPane，然后，再将这个JScrollPane放到刚才面板A（上面提到过）上。

现在知道，如何将jfreechart和jtable,怎么结合的了吧。

如果你有java swing方面的经验，很容易理解的。

[color=red]置于你说的，我给你发的代码无法运行，那说明我们用的不是同一版本的jfreechart,在我这边是可以运行的。
我的版本是：jfreechart 1.0.13[/color]

说白了，你现在需要做的是，修改代码中的数据，变为你自己的数据，然后删除一些不必要的东西，例如右边的那部分。

很简单的。
