使用JFreeChart增強(qiáng)Java繪圖功能

在給用戶演示軟件產(chǎn)品時(shí)，我們往往發(fā)現(xiàn)客戶最初更感興趣的是我們程序的用戶界面，而不是程序的功能本身。也正因如此，圖形用戶界面的應(yīng)用程序一經(jīng)出現(xiàn)即廣受歡迎，界面友好的Windows操作系統(tǒng)雖然性能很不穩(wěn)定、安全漏洞百出，仍有無(wú)數(shù)用戶有怨無(wú)悔地追隨就是一個(gè)典型的例子。計(jì)算機(jī)編程技術(shù)發(fā)展到今天，遇到數(shù)據(jù)展示時(shí)人們已不滿足于枯燥的列表方式，而更喜歡色彩豐富、一目了然的的圖形效果。于是，在許多軟件產(chǎn)品中會(huì)涉及到制圖功能。     本文將介紹是一組功能強(qiáng)大、靈活易用的Java制圖API——JFreeChart，使用JFreeChart我們可以極大地增強(qiáng)Java應(yīng)用程序的高級(jí)制圖功能，生成多種通用性的圖表，包括餅圖、柱狀圖、折線圖、甘特圖等。對(duì)于要在Swing或Web應(yīng)用程序中加入自制圖表的Java開發(fā)者而言，JFreeChart無(wú)疑是一種理想的選擇。   下面以生成最常用的餅圖（Pie Chart）為例，介紹一下使用JFreeChart制圖的基本過(guò)程：   一．獲取JFreeChart最新版本   JFreeChart為開放源碼自由軟件，可以到下述網(wǎng)址免費(fèi)下載：http://www.jfree.org/jfreechart/，目前最新版本為v1.0.0-pre2版，下載并解壓縮后，將其中包含的下述兩個(gè).jar文件加入到計(jì)算機(jī)編譯和運(yùn)行環(huán)境的環(huán)境變量CLASSPATH中：jcommon-1.0.0-pre2.jar，jfreechart-1.0.0-pre2.jar。     二．開發(fā)Java Application，使用JFreeChart API實(shí)現(xiàn)創(chuàng)建餅圖的功能，源代碼如下： 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 = "夢(mèng)澤科技員工學(xué)歷情況統(tǒng)計(jì)";   DefaultPieDataset piedata = new DefaultPieDataset();   piedata.setValue("大專", 8.1);   piedata.setValue("大學(xué)", 27.6);   piedata.setValue("碩士", 53.2);   piedata.setValue("博士及以上", 19.2);   piedata.setValue("大專以下", 1.9);   JFreeChart chart = ChartFactory.createPieChart(title, piedata, true, true, true);   chart.setTitle(new TextTitle(title, new Font("宋體", Font.BOLD, 25)));   chart.addSubtitle(new TextTitle("最后更新日期：2005年5月19日", new Font("楷書", 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．編譯運(yùn)行上述源程序，生成的餅圖文件"PieChart.jpg"效果如下：     關(guān)于上述應(yīng)用程序使用的JFreeChart API，可查閱JFreeChart提供的在線API文檔，以獲取更詳細(xì)的信息，其URL為http://www.jfree.org/jfreechart/javadoc/。讀者可嘗試參照上述例程、并借助于API 文檔創(chuàng)建其他類型的圖表。 需要說(shuō)明的是，JFreeChart雖是一個(gè)開源（open source）項(xiàng)目——API可以免費(fèi)下載、API文檔可以免費(fèi)在線查閱，其官方開發(fā)教程卻是要花錢（US$39.95）購(gòu)買的，相關(guān)URL為 http://www.object-refinery.com/jfreechart/guide.html。

一般的創(chuàng)建圖表的過(guò)程為：

1．  從數(shù)據(jù)庫(kù)里讀取數(shù)據(jù)

2．  將數(shù)據(jù)保存到圖表對(duì)應(yīng)的數(shù)據(jù)集對(duì)象中

3．  創(chuàng)建坐標(biāo)軸對(duì)象

4．  創(chuàng)建Renderer對(duì)象

5．  創(chuàng)建Plot對(duì)象

6．  創(chuàng)建JfreeChart對(duì)象

7．  生成圖片文件（或者二進(jìn)制流）

以JfreeChart提供的Web應(yīng)用的例子來(lái)說(shuō)明一下以上幾個(gè)步驟：

一．柱圖。

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("");//創(chuàng)建坐標(biāo)軸

                     BarRenderer renderer = new BarRenderer();//創(chuàng)建Renderer

                     renderer.setItemURLGenerator(new StandardCategoryURLGenerator("xy_chart.jsp","series","section"));//創(chuàng)建URLGenerator.再不需要連接的情況下將第一個(gè)參數(shù)設(shè)置成"###"就可以了

            renderer.setToolTipGenerator(new StandardCategoryToolTipGenerator());//創(chuàng)建提示標(biāo)簽

                     Plot plot = new CategoryPlot(dataset, categoryAxis, valueAxis, renderer);//創(chuàng)建圖表區(qū)域?qū)ο?/p>

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

                     chart.setBackgroundPaint(java.awt.Color.white);//創(chuàng)建圖表

                     //  Write the chart image to the temporary directory

                     ChartRenderingInfo info = new ChartRenderingInfo(new StandardEntityCollection());//該工具類上面沒有介紹，在鼠標(biāo)移動(dòng)到圖片時(shí)顯示提示信息是用Map實(shí)現(xiàn)的，這些Map是用該類生成的。

                     filename = ServletUtilities.saveChartAsPNG(chart, 500, 300, info, session);//保存圖表為文件

                     //  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．圖表顯示：

<%

       ......

    String graphURL = request.getContextPath() + "/servlet/DisplayChart?filename=" + filename;//顯示圖片的Servlet全路徑名，另外文件名作為該Servlet的參數(shù)

       ......

%>

......

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

src指定了servlet的全路徑名，usermap指定了使用的熱點(diǎn)。

該Servlet必須在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>

該Servlet的作用就是將圖片文件的二進(jìn)制流數(shù)據(jù)寫道response的輸出流中，在客戶端也就顯示成了圖片。
