JFreeChart实现饼状图、柱状图和折线图以及各类报表

1.饼状图的CS架构实现：


 
实现代码如下： package servlet; import java.awt.Container;
import java.awt.Font; import javax.swing.JPanel; import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PiePlot;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.data.general.PieDataset;
import org.jfree.ui.ApplicationFrame;
import org.jfree.ui.RefineryUtilities; /**

 * @version V1.0  
 */
public class PieCharts extends ApplicationFrame {  public PieCharts(String s) {
  super(s);
  setContentPane(createDemoPanel());
  // TODO Auto-generated constructor stub
 }  public static JPanel createDemoPanel() {
  // 生成图表面板
  JFreeChart jfreechart=createChart(createDataset());
  return new ChartPanel(jfreechart);
 }  private static JFreeChart createChart(Object createDataset) {
  // TODO Auto-generated method stub
  return null;
 }  //生成饼图数据集对象
 public static PieDataset createDataset(){
  DefaultPieDataset defaultpiedataset=new DefaultPieDataset();
  defaultpiedataset.setValue("MANAGER", 10.02D);
  defaultpiedataset.setValue("MARKET", 20.23D);
  defaultpiedataset.setValue("DEVELOP", 60.02D);
  defaultpiedataset.setValue("OEM", 10.02D);
  defaultpiedataset.setValue("OTHERS", 5.11D);
  return defaultpiedataset;
 }  //生成图表主对象JFreeChart
 public static JFreeChart createChart(PieDataset piedataset){
  JFreeChart jfreechart=ChartFactory.createPieChart("CityInfoPort Company",piedataset,true,true,false);
  //获得图表显示对象
  PiePlot pieplot=(PiePlot)jfreechart.getPlot();
  //设置图表标签字体
  pieplot.setLabelFont(new Font("SansSerif",Font.BOLD,12));
  pieplot.setNoDataMessage("No data available");
  pieplot.setCircular(true);
  pieplot.setLabelGap(0.01D);//间距
  return jfreechart;
  //定义图表对象
 }

 private static final long serialVersionUID = 1L;  /**

  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  PieCharts fjc=new PieCharts("CityInfoPort Company");
  fjc.pack();
  RefineryUtilities.centerFrameOnScreen(fjc);
  fjc.setVisible(true);
 } }
  2.折线图的CS架构实现

  实现代码如下: package servlet; import java.awt.Container; import javax.swing.JPanel; 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.CategoryPlot;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.DefaultCategoryDataset;
import org.jfree.ui.ApplicationFrame;
import org.jfree.ui.RefineryUtilities; /**  
 * @Title: 折线图的CS架构实现
 * @Package servlet
 * @Description:
 * @author lzh
 * @date Dec 5, 2011 3:39:41 PM   
 * @version V1.0  
 */
public class LineCharts extends ApplicationFrame{  private static final long serialVersionUID = 0L;
 
 public LineCharts(String s) {
  super(s);
  setContentPane(createDemoLine());
 }  public static void main(String args[]){
  LineCharts fjc=new LineCharts("Line");
  fjc.pack();
  RefineryUtilities.centerFrameOnScreen(fjc);
  fjc.setVisible(true);
 }
 
 //生成显示图表的面板
 public static JPanel createDemoLine(){
  JFreeChart jfreechart=createChart(createDataset());
  return new ChartPanel(jfreechart);
  
 }  //生成图表主对象JFreeChart
 private static JFreeChart createChart(DefaultCategoryDataset linedataset) {
  //定义图表对象
  JFreeChart chart=ChartFactory.createLineChart("Line","Time","Sale(million)",linedataset,PlotOrientation.VERTICAL,true,true,false);
  CategoryPlot plot=chart.getCategoryPlot();
  NumberAxis rangeAxis=(NumberAxis)plot.getRangeAxis();
  rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
  rangeAxis.setAutoRangeIncludesZero(true);
  rangeAxis.setUpperMargin(0.20);
  rangeAxis.setLabelAngle(Math.PI/2.0);
  return chart;
 }  //生成数据
 private static DefaultCategoryDataset createDataset() {
  DefaultCategoryDataset linedataset=new DefaultCategoryDataset();
  //各曲线名称
  String series1="TV";
  String series2="PC";
  String series3="WASH";
  
  //横轴名称（列名称）
  String type1="JAN";
  String type2="FEB";
  String type3="MAR";
  
  linedataset.addValue(0.0,series1,type1);
  linedataset.addValue(4.2,series1,type2);
  linedataset.addValue(3.9,series1,type3);
  
  linedataset.addValue(1.0,series2,type1);
  linedataset.addValue(5.2,series2,type2);
  linedataset.addValue(7.9,series2,type3);
  
  linedataset.addValue(2.0,series3,type1);
  linedataset.addValue(9.2,series3,type2);
  linedataset.addValue(8.9,series3,type3);
  
  
  
  return linedataset;
 } }
3.柱状图的CS架构实现

  实现代码如下：BarCharts.javapackage servlet;
import java.awt.Color;import java.awt.Font;
import javax.swing.JPanel;
import org.jfree.chart.ChartFactory;import org.jfree.chart.ChartPanel;import org.jfree.chart.JFreeChart;import org.jfree.chart.labels.StandardCategoryItemLabelGenerator;import org.jfree.chart.plot.CategoryPlot;import org.jfree.chart.plot.PlotOrientation;import org.jfree.chart.renderer.category.BarRenderer3D;import org.jfree.data.category.CategoryDataset;import org.jfree.data.general.DatasetUtilities;import org.jfree.ui.ApplicationFrame;import org.jfree.ui.RefineryUtilities;
public class BarCharts extends ApplicationFrame{ private static final long serialVersionUID = 1L; public BarCharts(String title) { super(title); setContentPane(createDemoBar()); }
//生成显示图表的面板 public static JPanel createDemoBar() { JFreeChart jfreechart=createChart(createDataset()); return new ChartPanel(jfreechart); }
//生成图表主对象JFreeChart public static JFreeChart createChart(CategoryDataset dataset) { JFreeChart chart=ChartFactory.createBarChart3D("Fruit sales","Fruit","Sales",dataset,PlotOrientation.VERTICAL,true,false,false);//第三个true表示显示每个颜色柱子的柱名 CategoryPlot plot=chart.getCategoryPlot();//设置图的高级属性 BarRenderer3D renderer=new BarRenderer3D();//3D属性修改 renderer.setBaseOutlinePaint(Color.BLACK);//设置边框颜色为black renderer.setWallPaint(Color.gray);//设置wall的颜色为gray renderer.setItemLabelGenerator(new StandardCategoryItemLabelGenerator());//设置柱顶数据，API中居然没有StandardCategoryItemLabelGenerator这个类 renderer.setItemLabelFont(new Font("黑体",Font.PLAIN,12));//设置柱顶数据字体 renderer.setItemLabelsVisible(true);//打开ItemLabel开关 plot.setRenderer(renderer);//将修改后的属性值保存到图中 plot.setForegroundAlpha(0.6f); return chart; }
//生成数据 public static CategoryDataset createDataset(){ double[][] data=new double[][]{{672,766,223,540,126},{325,521,210,340,106},{332,256,523,240,526}};//设置数据 String[] rowKeys={"Apple","Pear","BANANA"};//行标志 String[] columnKeys={"Peking","ShangHai","ChengDu","ChongQing","GuangZhou"};//列标志 CategoryDataset linedataset=DatasetUtilities.createCategoryDataset(rowKeys,columnKeys,data);//建立数据集 return linedataset; } public static void main(String args[]){ BarCharts fjc=new BarCharts("BarCharts"); fjc.pack(); RefineryUtilities.centerFrameOnScreen(fjc); fjc.setVisible(true); }}
