如何在面板上添加JFreechart? [英] How to add a JFreechart to a Panel?
本文介绍了如何在面板上添加JFreechart?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图寻找答案以使该功能正常运行，但没有成功，我将失去理智，所以我的问题就在这里.
我最近下载了JFreeChart来创建图表，并在我的GUI中实现它们. 这是要在其中插入图形(用白色标记)的GUI和面板:

我已经使用NetBeans编辑器构造了GUI和一个在线提供的JFreeChart示例. 下面是我的GUI的代码:
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;
}
/* *************************************

}
这是结果:

我正在初始化图表并将其添加到主类构造函数中，下面是该图表的代码.我必须避免发布超过字符数限制的整个代码，但是这里是完整代码的URL(使用NetBeans初始化的Swing组件):解决方案
不要让GUI设计者来决定您的设计.根据建议此处使用它来管理各个面板.如果没有.form文件，则无法编辑GUI项目.我只是使用FlowLayout添加了图表，所以您可以看到它而无需更改initComponents().

I've tried looking for answers to get this working but haven't managed to do so and I am about to lose my mind so here goes my question.
I've recently downloaded JFreeChart to create so charts and implement them in the GUI I had. Here's the GUI and the panel where I want to insert the graph (marked in white):
reports1 http://www.freeimagehosting.net/newuploads/eff3r.png reports2 http://www.freeimagehosting.net/newuploads/v5sty.png
I have used NetBeans editor to construct the GUI and a JFreeChart example available online. Below is the code for my GUI:

}
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;

}
And this is the result:

I am initializing and adding the chart in the main class constructor and right below is the code for the graph. I had to refrain from posting the entire code as it went above the character limits, however here is an url for the complete code (with the Swing components initialization by NetBeans): http://tny.cz/8a4e8b2f
Any hint for solutions?
THanks in advance and let me know if anything else is needed.

Don't let the GUI designer dictate your design. Use it, if at all, to manage individual panels, as suggested here. It's not possible to edit a GUI project without the .form file; I just added your chart using a FlowLayout so you can see it, without altering initComponents().
