本来可以用cwolf的。但是cwolf不能做统计。返照他的功能自己做了一个。觉得还不错。开发的时候省略了很多JFreeChart的东西。直接做一个连数据的CLASS就可以了。下面是开发指南，希望对要用JFREECHART的人有帮助。
优点：
简化了生成图形的繁琐代码，用TagLib封装了。只要数据对象就可以了
缺点：
只能生成饼图 和 柱图 其他图还没有做
Sonic Chart TutorialXML:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> SETUP for installing the tag library(First time user) How to Install (Making sure you have the Jar File)Put the following JAR files of the /lib directory into your web applications /WEB-INF/lib directory: l Sonic. jar l jfreechart-0.9.20.jar l jcommon-0.9.5.jar l Commons-logging. jar You must add the following code to the web.XML file t o let yours project know the location of the TLDS <servlet>
<servlet-name>DisplayChart</servlet-name>
<servlet-class>rg.jfree.chart.servlet.DisplayChart</servlet-class>
</servlet> |
Additionally you should provide a servlet-mapping to tell the container which URL maps to your sonic rendering servlet. <servlet-mapping>
<servlet-name>DisplayChart</servlet-name>
<url-pattern>servlet/DisplayChart</url-pattern>
</servlet-mapping> |
Additionally you should proide a taglib to tell container which URL to find sonic.tld <taglib> <taglib-uri>/WEB-INF/sonic.tld</taglib-uri> <taglib-location>/WEB-INF/sonic.tld</taglib-location> </taglib> |
1.How to Create a PeChart DatasetProdUCer l Createa a Java file sUCh ByUsingPeople_PieDB.Java Note: 1. In ByUsingPeople_PieDB.Java file you must implements ProdUCtDataSetInterface, Serializable Below is ByUsingPeople_PieDB.Java detail import org.jfree.data.DefaultPieDataset; import Java.util.ArrayList; import net.Javasp.www.chartfactorymethod.creator.ChartCreatorInterface.ProdUCtDataSetInterface;import Java.io.Serializable; public class IndustryGroupRequire implements ProdUCtDataSetInterface, Serializable{ public ArrayList prodUCeDataset() throws Exception { // Create a DefaultPieDataset object DefaultPieDataset ds = new DefaultPieDataset(); String total = null; String percent = null; ArrayList list = new ArrayList(); // The data which need set into DefaultPieDataset object ds.setValue("第一产业比重", 36); ds.setValue("第二产业比重", 24); ds.setValue("第三产业比重", 20); // Below chart show total info String[] totalname = {"所占比重：", ""}; list.add(ds); list.add("80"+"%"); list.add(""); list.add(totalname); //3 list.add("other"); // return list; } } 1. Create a jsp file sUCh as piechart.jsp Note: 1. The taglib sonic attribute must same to <jsp useBean id> attribute SUCh as <sonic:plotchart id=”pieData” …> and <jsp:useBean id=”pieData” …> 2. type="piechart" type attribute must be “piechart” Below is piechart.jsp detail piechart.jsp <%@ page contentType="text/html; charset=GB2312" %> <%@taglib uri='/WEB-INF/sonic.tld' prefix='sonic' %> <jsp:useBean id="pieData" class=" net.Javasp.www.piechartdataset.ByUsingPeople_PieDB "/> <html> <head> <title> 按行业分组的需求人数 </title> </head> <body bgcolor="#ffffff"> <div align="center"> <sonic:plotchart id="pieData" type="piechart" name="按行业分组的需求人数" hight="700" width="700" /> </div> </body> </html> 2.How to Create a Column Chart DatasetProdUCer Note: l Createa a Java file sUCh SupplyTotalCount.Java In ByUsingPeople_PieDB.Java file you must implements ProdUCtDataSetInterface, Serializable import net.Javasp.www.chartfactorymethod.creator.ChartCreatorInterface.ProdUCtDataSetInterface; import Java.io.Serializable; import Java.util.ArrayList; import org.jfree.data.CategoryDataset; import org.jfree.data.DatasetUtilities; /** * <p>Title: Colum3DprodUCeDataset</p> * <p>Description: </p> * <p>Copyright: Copyright (c) 2004</p> * <p>Company: www.Javasp.net</p> * @author Jstar * @version 1.0 */ public class SupplyTotalCount implements ProdUCtDataSetInterface, Serializable { public SupplyTotalCount() { } public ArrayList prodUCeDataset() throws Exception { int total = 0; int percent = 0; ArrayList list = new ArrayList(); //---------------------------------需求人数-----求职人数 double[][] date = new double[][] {{322, 261}, {128, 240}}; String[] rowKeys = {"上期结转", "本期新增"}; String[] columnKeys = {"需求人数", "求职人数"}; String[] totalname = {"需求人数", "求职人数"}; CategoryDataset ds = DatasetUtilities.createCategoryDataset(rowKeys,columnKeys, date); //total for (int i = 0; i < 1; i++) { for (int j = 0; j < date.length; j++) { total += date[j][i]; } } //percent for (int a = 1; a < 2; a++) { for (int b = 0; b < date.length ; b++) { percent += date[b][a]; } } list.add(ds);//0 list.add(Integer.toString(total));//1 list.add(Integer.toString(percent));//2 list.add(totalname);//3 list.add("other");//4 return list; } } 2. Create a jsp file sUCh as columnchart.jsp Note: 3. The taglib sonic attribute must same to <jsp useBean id> attribute SUCh as <sonic:plotchart id=” columndata” …> and <jsp:useBean id=” columndata” …> 4. type=" columndata " type attribute must be “columndata” Below is piechart.jsp detail piechart.jsp <%@ page contentType="text/html; charset=GB2312" %> <%@taglib uri='/WEB-INF/sonic.tld' prefix='sonic' %> <jsp:useBean id="columndata " class=" net.Javasp.www.columndataset.SupplyTotalCount "/> <html> <head> <title> 供求总体人数 </title> </head> <body bgcolor="#ffffff"> <div align="center"> <sonic:plotchart id=" columndata " type=" columchart " name="供求总体人数" width="500" hight="350 " /> </div> </body> </html>
