效果图:
通过工具栏切换成折线图:
1.部署好springMVCproject
2.*****在lib中增加ECharts-2.2.4.jar 下载地址:http://git.oschina.net/free/ECharts
3.由于要用到fastJson所以还要导入其所需的jar包fastjson-1.2.5-sources.jar 和fastjson-1.2.5.jar
4.springMVC的服务层的代码:EchartsT.java
package com.service; import com.github.abel533.echarts.Label; import com.github.abel533.echarts.Option; import com.github.abel533.echarts.Title; import com.github.abel533.echarts.axis.CategoryAxis; import com.github.abel533.echarts.axis.ValueAxis; import com.github.abel533.echarts.code.LineType; import com.github.abel533.echarts.code.Magic; import com.github.abel533.echarts.code.MarkType; import com.github.abel533.echarts.code.Orient; import com.github.abel533.echarts.code.PointerType; import com.github.abel533.echarts.code.SelectedMode; import com.github.abel533.echarts.code.Tool; import com.github.abel533.echarts.code.Trigger; import com.github.abel533.echarts.code.X; import com.github.abel533.echarts.code.Y; import com.github.abel533.echarts.data.Data; import com.github.abel533.echarts.data.PointData; import com.github.abel533.echarts.feature.MagicType; import com.github.abel533.echarts.series.Bar; import com.github.abel533.echarts.series.Funnel; import com.github.abel533.echarts.series.Line; import com.github.abel533.echarts.series.Map; import com.github.abel533.echarts.series.MapLocation; import com.github.abel533.echarts.series.Pie; import com.github.abel533.echarts.style.ItemStyle; import com.github.abel533.echarts.style.LineStyle; /** * @author lyx * * 2015-6-12下午1,34,50 * *springechart.com.service.EchartsT */ public class EchartsT { /** * @return * 堆积图 */ public Option stackChart() { Option option = new Option(); //标题 option.title("获取信息途径所占比重"); //提示框 option.tooltip().trigger(Trigger.axis); option.tooltip().axisPointer().type(PointerType.shadow); //图例说明 option.legend().data("直接訪问","邮件营销","联盟广告","视频广告","搜索引擎","百度","谷歌","必应","其它"); //工具栏 option.toolbox().show(true).orient(Orient.vertical).x(X.right).y(Y.center) .feature(Tool.mark,Tool.dataView,Tool.dataZoom,new MagicType(Magic.bar,Magic.line,Magic.stack,Magic.tiled), Tool.restore,Tool.saveAsImage); //是否启用拖拽重计算特性 option.calculable(true); //x轴 -类目轴 option.xAxis(new CategoryAxis().data("周一","周二","周三","周四","周五","周六","周日")); //Y轴 -值轴 option.yAxis(new ValueAxis()); //系列 ,当中stack表示堆栈图的设置 Bar bar1 = new Bar("直接訪问"); bar1.data(320, 332, 301, 334, 390, 330, 320); Bar bar2 = new Bar("邮件营销"); bar2.stack("广告"); bar2.data(120, 132, 101, 134, 90, 230, 210); Bar bar3 = new Bar("联盟广告"); bar3.stack("广告"); bar3.data(220, 182, 191, 234, 290, 330, 310); Bar bar4 = new Bar("视频广告"); bar4.stack("广告"); bar4.data(150, 232, 201, 154, 190, 330, 410); Bar bar5 = new Bar("搜索引擎"); bar5.data(862, 1018, 964, 1026, 1679, 1600, 1570); //标记线 bar5.markLine().itemStyle().normal().lineStyle(new LineStyle().type(LineType.dashed)); bar5.markLine().data(new PointData().type(MarkType.min),new PointData().type(MarkType.max)); Bar bar6 = new Bar("百度"); bar6.stack("搜索引擎"); bar6.data(620, 732, 701, 734, 1090, 1130, 1120); Bar bar7 = new Bar("谷歌"); bar7.stack("搜索引擎"); bar7.data(120, 132, 101, 134, 290, 230, 220); Bar bar8 = new Bar("必应"); bar8.stack("搜索引擎"); bar8.data(60, 72, 71, 74, 190, 130, 110); Bar bar9 = new Bar("其它"); bar9.stack("搜索引擎"); bar9.data(62, 82, 91, 84, 109, 110, 120); //加入到系列中 option.series(bar1,bar2,bar3,bar4,bar5,bar6,bar7,bar8,bar9); return option; } }
5.控制层的代码:echartsContr.java
package com.controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.alibaba.fastjson.JSON; import com.github.abel533.echarts.Option; import com.service.EchartsT; /** * @author lyx * * 2015-6-12下午1:36:51 * *springechart.com.controller.echartsContr */ @Controller @RequestMapping("/echarts") public class echartsContr { EchartsT ech = new EchartsT(); /** * @param res * @return * * 堆栈图 */ @RequestMapping("/stackChart") public String stackChart(HttpServletRequest res) { Option option = ech.stackChart(); String opt = JSON.toJSONString(option); res.setAttribute("option", opt); return "/ec"; } }
6. ec.jsp 页面代码:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <!DOCTYPE html> <head> <meta charset="utf-8"> <title>ECharts</title> <script type="text/javascript" src="../js/jquery-1.11.3.min.js"></script> </head> <body> <!-- 为ECharts准备一个具备大小(宽高)的Dom --> <div id="main" style="height:600px"></div> <span style="white-space:pre"> </span><script type="text/javascript" src="../js/echarts.js"></script> <script type="text/javascript"> //路径配置 require.config({ paths:{ echarts: ‘../js‘ } }); //获得后台传过来的JSON数据 var opt =${option}; //设置主要样式 require( [ //须要什么图形就载入什么图形 这里仅仅用到了柱状图,仅仅需载入bar即可 ‘echarts‘, ‘echarts/chart/bar‘,//柱状图 ‘echarts/chart/line‘, //折线 ‘echarts/chart/pie‘, //椭圆 ‘echarts/chart/map‘, //地图 ‘echarts/chart/funnel‘ //漏斗 ], function(ec){ //初始化echart对象 var chart =ec.init(document.getElementById(‘main‘));//ec.init( $("#main")); chart.setOption(opt); }); </script> </body> </html>
7.生成后的页面源代码:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <!DOCTYPE html> <head> <meta charset="utf-8"> <title>ECharts</title> <script type="text/javascript" src="../js/jquery-1.11.3.min.js"></script> </head> <body> <!-- 为ECharts准备一个具备大小(宽高)的Dom --> <div id="main" style="height:600px"></div> <!-- ECharts单文件引入 --> <!-- <script src="http://echarts.baidu.com/build/dist/echarts.js"></script> --> <script type="text/javascript" src="../js/echarts.js"></script> <!-- <script type="text/javascript" src="js/echarts-all.js"></script> --> <script type="text/javascript"> //路径配置 require.config({ paths:{ echarts: ‘../js‘ } }); //获得后台传过来的JSON数据 var opt ={"calculable":true,"legend":{"data":["直接訪问","邮件营销","联盟广告","视频广告","搜索引擎","百度","谷歌","必应","其它"]},"series":[{"data":[320,332,301,334,390,330,320],"name":"直接訪问","type":"bar"},{"data":[120,132,101,134,90,230,210],"name":"邮件营销","stack":"广告","type":"bar"},{"data":[220,182,191,234,290,330,310],"name":"联盟广告","stack":"广告","type":"bar"},{"data":[150,232,201,154,190,330,410],"name":"视频广告","stack":"广告","type":"bar"},{"data":[862,1018,964,1026,1679,1600,1570],"markLine":{"data":[{"type":"min"},{"type":"max"}],"itemStyle":{"normal":{"lineStyle":{"type":"dashed"}}}},"name":"搜索引擎","type":"bar"},{"data":[620,732,701,734,1090,1130,1120],"name":"百度","stack":"搜索引擎","type":"bar"},{"data":[120,132,101,134,290,230,220],"name":"谷歌","stack":"搜索引擎","type":"bar"},{"data":[60,72,71,74,190,130,110],"name":"必应","stack":"搜索引擎","type":"bar"},{"data":[62,82,91,84,109,110,120],"name":"其它","stack":"搜索引擎","type":"bar"}],"title":{"text":"获取信息途径所占比重"},"toolbox":{"feature":{"mark":{"lineStyle":{"color":"#1e90ff","type":"dashed","width":2},"show":true,"title":{"mark":"辅助线开关","markClear":"清空辅助线","markUndo":"删除辅助线"}},"dataView":{"lang":["数据视图","关闭","刷新"],"readOnly":false,"show":true,"title":"数据视图"},"dataZoom":{"show":true,"title":{"dataZoom":"区域缩放","dataZoomReset":"区域缩放后退"}},"magicType":{"show":true,"title":{"line":"折线图切换","stack":"堆积","bar":"柱形图切换","tiled":"平铺"},"type":["bar","line","stack","tiled"]},"restore":{"show":true,"title":"还原"},"saveAsImage":{"lang":["点击保存"],"show":true,"title":"保存为图片","type":"png"}},"orient":"vertical","show":true,"x":"right","y":"center"},"tooltip":{"axisPointer":{"type":"shadow"},"trigger":"axis"},"xAxis":[{"data":["周一","周二","周三","周四","周五","周六","周日"],"type":"category"}],"yAxis":[{"type":"value"}]}; //设置主要样式 require( [ ‘echarts‘, ‘echarts/chart/bar‘, ‘echarts/chart/line‘, ‘echarts/chart/pie‘, ‘echarts/chart/map‘, ‘echarts/chart/funnel‘ ], function(ec){ //初始化echart对象 var chart =ec.init(document.getElementById(‘main‘));//ec.init( $("#main")); chart.setOption(opt); }); </script> </body> </html>
8.project完毕整代码下载:
參考站点:http://git.oschina.net/free/ECharts
通过上面站点作者所编写的ECharts-2.2.4.jar ,导入到我们project中这样我们的页面中的js代码。就能够如今项目的后台生成,并通过json转换成字符串传入到页面中,在jsp页面接收传入的json格式的字符串。后就能够生成我们设置的图表了。
