后台dom拼接xml，动态显示统计图

 这个东西让我好生头疼，贴代码吧

 // 两秒后模拟点击
 setTimeout(function() {
 // IE
 if(document.all) {
 document.getElementById("userQuery").click();
 }// 其它浏览器
 else {
 var e = document.createEvent("MouseEvents");
 e.initEvent("click", true, true);
 document.getElementById("userQuery").dispatchEvent(e);
 }
 }, 1000);
 $("#userQuery").click(function(){
 var $this = $(this);
 var companyCode=GetRequest()['companyCode'];
 $("#compAny").val(companyCode);
 //将queryStr传到后台，进行获取数据
 var queryStr = $this.parents('form').serialize();
 $.ajax({
 url: "../../userliebiao/userGraph.do",
 data: queryStr,
 type: "post",
 cache:false,
 dataType: "json",
 success: function (data) {
 var myChart;
 myChart = new FusionCharts("../../fusionCharts/Line.swf","myChartId", "1200", "400", "0" );
 myChart.setDataXML(data.xml); //调用后台的xml数据
 myChart.render("userPic"); //将数据送给div 进行显示},//如果后台有错
 error: function(XMLHttpRequest, textStatus, errorThrown) {
 console.log(XMLHttpRequest.status); //一切正常 200
 alert(XMLHttpRequest.status);
 console.log(XMLHttpRequest.readyState);
 //此阶段确认全部数据都已经解析为客户端可用的格式，解析已经完成。值为4表示数据解析完毕，可以通过XMLHttpRequest对象的相应属性取得数据。
 alert(XMLHttpRequest.readyState);
 console.log(textStatus);
 alert("出错了"+textStatus);}}); });

 后台方法：

 try {
 String subcaption = null;
 User user=new User();
 String type=this.getParam("cycle");
 if (type.equals("1")) {
 type="1,2";    //1：按天
 user.setDmType(type);
 }else if(type.equals("2")){
 type="4,2";    //1：按月
 user.setDmType(type);
 }else if(type.equals("3")){
 type="8,3";    //1：按年"minZu"
 user.setDmType(type);
 }
 SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
 String allTime=this.getParam("fcreatetime2");
 String compAny=this.getParam("compAny");
 Map<String, Object> map = new HashMap<String, Object>();
 if (allTime!=null || allTime!="") {
 String[] a=allTime.split(" 至 ");    //将时间分割为开始时间~结束时间
 String betime=a[0];
 String entime=a[1];
 subcaption=betime+" 至 "+entime;
 Date time1 = sdf.parse(betime);
 Date time2 = sdf.parse(entime);
 if (type!=""||compAny!="") {
 user.setDmType(type);
 user.setCompanyCode(compAny);
 }
 map.put("dmType",user.getDmType());    //将数据存到map，作为sql方法的参数
 map.put("companycode",user.getCompanyCode());
 map.put("beginTime",time1);
 map.put("overTime", time2);
 }
 List<Map> aa = los.userGraph(map);//执行sql语句
 Document document = DocumentHelper.createDocument();//创建dom节点
 //    if(!"3".equals(map.get("querytype").toString())){//如果不是按地区查询
 //    String yAxisMaxValue="50000"; //y轴最大值
 String xAxisName="注册日期";
 String yAxisName="注册人数";
 String numberSuffix="人"; //数字的后缀
 String xlable;

 String title = "登录人次统计";
 Element root = XmlDom4jUtils.addElementAndAttribute(document, "chart",
 "caption","注册人数统计 ","xAxisName","注册日期 ","yAxisName","注册人数",
 "yAxisMinValue","200","showValues","","alternateHGridColor",
 "FCB541","alternateHGridAlpha","20","divLineColor","FCB541","divLineAlpha","50",
 "canvasBorderColor","666666","baseFontColor","666666","lineColor","FCB541",
 "baseFont","Arial","baseFontSize","15","rotateYAxisName","0",
 "chartRightMargin","50","showBorder","0",
 "canvasBorderThickness ","1","showNames","",
 "numDivLines ","4",
 "numberSuffix",numberSuffix,
 //    "xAxisName",xAxisName,
 "subcaption",subcaption+" ",
 "showAlternateHGridColor","1",
 "canvasBorderColor","FFCCCC",
 "bgColor","FFFFFF,FFFFFF",
 "anchorRadius","2",//折线节点半径
 "bgColor","FFFFFF"
 );
 String ss;
 for (Map map2 : aa) {
 ss=(String) map2.get("CREATEDDATE");
 boolean a = ss.contains("月");
 if (a!=true) {
 if (type.equals("1,2")) {
 ss+="日";
 }
 if (type.equals("4,2")) {
 ss+="月";
 }
 if (type.equals("8,3")) {
 ss+="年";
 }
 }
 map2.put("CREATEDDATE", ss);
 XmlDom4jUtils.addChildrenAndAttribute(root,"set","label",""+map2.get("CREATEDDATE")+"","value",""+map2.get("VISITORID")+"");
 }

 Element styles = XmlDom4jUtils.addChildren(root, "styles");
 Element definition = XmlDom4jUtils.addChildren(styles,"definition");
 XmlDom4jUtils.addChildrenAndAttribute(definition,"style","name","Anim1","type","animation","param","_xscale","start","0","duration","1");
 XmlDom4jUtils.addChildrenAndAttribute(definition,"style","name","Anim2","type","animation","param","_alpha","start","0","duration","0.6");
 Element application = XmlDom4jUtils.addChildren(styles,"application");
 XmlDom4jUtils.addChildrenAndAttribute(application,"apply","toObject","DIVLINES","styles","Anim1");
 XmlDom4jUtils.addChildrenAndAttribute(application,"apply","toObject","HGRID","styles","Anim2");
 XmlDom4jUtils.addChildrenAndAttribute(application,"apply","toObject","DATALABELS","styles","DataShadow,Anim2");

 Map<String, Object> mapp = new HashMap<String, Object>();
 mapp.put("xml", document.asXML());
 String json = JsonUtils.mapToJson(mapp);
 outStringData(json);
 } catch (ParseException e) {
 e.printStackTrace();
 }

 核心是sql语句：

 select count(i.createddate) as visitorId,substr(u.createddate,${dmType}) as createddate
 from ** u,// i
 where u.userinfoids = i.ids
 <if test="beginTime !=null and beginTime !=''">
 　　<![CDATA[
 　　　　and substr(u.createddate,0,10) >= #{beginTime}
 　　]]>
 </if>
 <if test="overTime !=null and overTime !=''"> 　
 　　<![CDATA[
 　　　　and substr(u.createddate,0,10) <= #{overTime}
 　　]]>
 </if>
 <if test="companycode !=null and companycode !=''">
 and u.COMPANYCODE = #{companycode}
 </if>
 <![CDATA[
 group by substr(u.createddate, ${dmType})
 order by substr(u.createddate, ${dmType}) asc
 ]]>

 dao代码：

 //图形统计
 public List<Map> **(Map<String, Object> map){
 //    super.sqlSessionTemplate.selectMap("路径", map);
 return super.sqlSessionTemplate.selectList("路径", map);

 }
