请教将JFreechar嵌入GUI

wangyang3092 2006-11-23 10:38:01
我做了一个JFreeChart的例子想把它嵌入到我已经做好的GUI中怎么嵌入啊，我想了很多办法都没成功，请教各位帮我实现，最好写原代码，毕竟我是个初学者，谢谢各位！
JFreeChart代码如下
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.axis.NumberAxis;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.chart.plot.XYPlot;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;
import org.jfree.ui.ApplicationFrame;
import org.jfree.ui.RefineryUtilities;


public class XYSeriesDemo extends ApplicationFrame {


public XYSeriesDemo(final String title) {

super(title);
final XYSeries series = new XYSeries("负荷—变形曲线");
series.add(0.0, 0.0);
series.add(5.0, 6.0);
series.add(8.0, 10.0);
series.add(12.5, 18.0);
series.add(17.3, 18.0);
series.add(21.2, 19.0);
series.add(22.9, 100.0);
series.add(25.6, 100.0);
series.add(30.0, 10.0);
final XYSeriesCollection data = new XYSeriesCollection(series);
final JFreeChart chart = ChartFactory.createXYLineChart(
"HuaLong Test ",
"负荷(N)",
"变形1(mm)",
data,
PlotOrientation.VERTICAL,
true,
true,
false
);

final XYPlot plot = (XYPlot) chart.getPlot();
final NumberAxis axis = (NumberAxis) plot.getRangeAxis();
axis.setAutoRangeIncludesZero(false);
axis.setAutoRangeMinimumSize(1.0);
final ChartPanel chartPanel = new ChartPanel(chart);
chartPanel.setPreferredSize(new java.awt.Dimension(1010, 710));
setContentPane(chartPanel);

}


public static void main(final String[] args) {

final XYSeriesDemo demo = new XYSeriesDemo("负荷—变形曲线窗口 ");
demo.pack();
RefineryUtilities.centerFrameOnScreen(demo);
demo.setVisible(true);

}

}
GUI代码如下：

其实这是一个很简单的问题啊，添加布局管理器，然后把根据chart构建的ChartPanel添加到布局管理器中去就可以了。

运行上面的MIS。

其实就是把一个根据一个Chart构建一个ChartPanel，这个ChartPanel是一个Component，就可以像对待swing中其他Component一样去对待它了
