使用JFreeChart增强Java绘图功能

在给用户演示软件产品时，我们往往发现客户最初更感兴趣的是我们程序的用户界面，而不是程序的功能本身。也正因如此，图形用户界面的应用程序一经出现即广受欢迎，界面友好的Windows操作系统虽然性能很不稳定、安全漏洞百出，仍有无数用户有怨无悔地追随就是一个典型的例子。计算机编程技术发展到今天，遇到数据展示时人们已不满足于枯燥的列表方式，而更喜欢色彩丰富、一目了然的的图形效果。于是，在许多软件产品中会涉及到制图功能。     本文将介绍是一组功能强大、灵活易用的Java制图API——JFreeChart，使用JFreeChart我们可以极大地增强Java应用程序的高级制图功能，生成多种通用性的图表，包括饼图、柱状图、折线图、甘特图等。对于要在Swing或Web应用程序中加入自制图表的Java开发者而言，JFreeChart无疑是一种理想的选择。   下面以生成最常用的饼图（Pie Chart）为例，介绍一下使用JFreeChart制图的基本过程：   一．获取JFreeChart最新版本   JFreeChart为开放源码自由软件，可以到下述网址免费下载：http://www.jfree.org/jfreechart/，目前最新版本为v1.0.0-pre2版，下载并解压缩后，将其中包含的下述两个.jar文件加入到计算机编译和运行环境的环境变量CLASSPATH中：jcommon-1.0.0-pre2.jar，jfreechart-1.0.0-pre2.jar。     二．开发Java Application，使用JFreeChart API实现创建饼图的功能，源代码如下： 源文件：PieChart.java import java.io.*; import java.awt.*; import org.jfree.chart.*; import org.jfree.chart.title.TextTitle; import org.jfree.data.general.*; public class PieChart{  public static void main(String[] args){     String title = "梦泽科技员工学历情况统计";   DefaultPieDataset piedata = new DefaultPieDataset();   piedata.setValue("大专", 8.1);   piedata.setValue("大学", 27.6);   piedata.setValue("硕士", 53.2);   piedata.setValue("博士及以上", 19.2);   piedata.setValue("大专以下", 1.9);   JFreeChart chart = ChartFactory.createPieChart(title, piedata, true, true, true);   chart.setTitle(new TextTitle(title, new Font("宋体", Font.BOLD, 25)));   chart.addSubtitle(new TextTitle("最后更新日期：2005年5月19日", new Font("楷书", Font.ITALIC, 18)));   chart.setBackgroundPaint(Color.white);   try {    ChartUtilities.saveChartAsJPEG(new File("PieChart.jpg"), chart, 360, 300);   } catch (IOException exz) {    System.out.print("....Cant′t Create image File");   }     }  }     三．编译运行上述源程序，生成的饼图文件"PieChart.jpg"效果如下：     关于上述应用程序使用的JFreeChart API，可查阅JFreeChart提供的在线API文档，以获取更详细的信息，其URL为http://www.jfree.org/jfreechart/javadoc/。读者可尝试参照上述例程、并借助于API 文档创建其他类型的图表。 需要说明的是，JFreeChart虽是一个开源（open source）项目——API可以免费下载、API文档可以免费在线查阅，其官方开发教程却是要花钱（US$39.95）购买的，相关URL为 http://www.object-refinery.com/jfreechart/guide.html。

一般的创建图表的过程为：

1．  从数据库里读取数据

2．  将数据保存到图表对应的数据集对象中

3．  创建坐标轴对象

4．  创建Renderer对象

5．  创建Plot对象

6．  创建JfreeChart对象

7．  生成图片文件（或者二进制流）

以JfreeChart提供的Web应用的例子来说明一下以上几个步骤：

一．柱图。

public static String generateBarChart(Date hitDate, HttpSession session, PrintWriter pw) {

              String filename = null;

              try {

                     //  Retrieve list of WebHits

                     WebHitDataSet whDataSet = new WebHitDataSet();

                     //  Throw a custom NoDataException if there is no data

                     if (list.size() == 0) {

                            System.out.println("No data has been found");

                            throw new NoDataException();

                     }

                      //  Create and populate a CategoryDataset

                     Iterator iter = list.listIterator();

            DefaultCategoryDataset dataset = new DefaultCategoryDataset();

                     while (iter.hasNext()) {

                            WebHit wh = (WebHit)iter.next();

                dataset.addValue(new Long(wh.getHitCount()), "Hits", wh.getSection());

                     //  Create the chart object

                     CategoryAxis categoryAxis = new CategoryAxis("");

                     ValueAxis valueAxis = new NumberAxis("");//创建坐标轴

                     BarRenderer renderer = new BarRenderer();//创建Renderer

                     renderer.setItemURLGenerator(new StandardCategoryURLGenerator("xy_chart.jsp","series","section"));//创建URLGenerator.再不需要连接的情况下将第一个参数设置成"###"就可以了

            renderer.setToolTipGenerator(new StandardCategoryToolTipGenerator());//创建提示标签

                     Plot plot = new CategoryPlot(dataset, categoryAxis, valueAxis, renderer);//创建图表区域对象

                     JFreeChart chart = new JFreeChart("", JFreeChart.DEFAULT_TITLE_FONT, plot, false);

                     chart.setBackgroundPaint(java.awt.Color.white);//创建图表

                     //  Write the chart image to the temporary directory

                     ChartRenderingInfo info = new ChartRenderingInfo(new StandardEntityCollection());//该工具类上面没有介绍，在鼠标移动到图片时显示提示信息是用Map实现的，这些Map是用该类生成的。

                     filename = ServletUtilities.saveChartAsPNG(chart, 500, 300, info, session);//保存图表为文件

                     //  Write the image map to the PrintWriter

                     pw.flush();

              } catch (NoDataException e) {

                     System.out.println(e.toString());

                     filename = "public_nodata_500x300.png";

              } catch (Exception e) {

                     System.out.println("Exception - " + e.toString());

                     e.printStackTrace(System.out);

                     filename = "public_error_500x300.png";

              }

              return filename;

       }

二．图表显示：

<%

       ......

    String graphURL = request.getContextPath() + "/servlet/DisplayChart?filename=" + filename;//显示图片的Servlet全路径名，另外文件名作为该Servlet的参数

       ......

%>

......

<img src="<%= graphURL %>" width=500 height=300 border=0 usemap="#<%= filename %>">

src指定了servlet的全路径名，usermap指定了使用的热点。

该Servlet必须在WEB-INF/web.xml文件中配置：

<servlet>

    <servlet-name>DisplayChart</servlet-name>

    <servlet-class>org.jfree.chart.servlet.DisplayChart</servlet-class>

  </servlet>

   <servlet-mapping>

        <servlet-name>DisplayChart</servlet-name>

        <url-pattern>/servlet/DisplayChart</url-pattern>

</servlet-mapping>

该Servlet的作用就是将图片文件的二进制流数据写道response的输出流中，在客户端也就显示成了图片。
