前提：已经确定从数据库读出的数据转换为Json格式，测试了下，结果为：
factor Value: {"rows":[{"cur_val":0.1150,"pow_val":26.2913,"consum":76.3807,"voltage":228.6632,"opt_time":"2015-05-26 20:37"},{"cur_val":0.1181,"pow_val":27.0956,"consum":76.3807,"voltage":229.4428,"opt_time":"2015-05-26 20:53"},```]} 数据量有些多 大概有1000多条
Controller：
@ResponseBody
@RequestMapping(value="/factor",method ={RequestMethod.GET,RequestMethod.POST})
public String getFactor(HttpServletRequest request,HttpServletResponse response)throws SgccException{
String factor=null;
System.out.println(request.getParameter("eqid"));
try {
factor=elcDataService.queryData(request.getParameter("acid"), request.getParameter("eqid"));
System.out.print("factor Value: ");
System.out.print(factor);
} catch (Exception e) {
e.printStackTrace();
}
return factor;
}
页面：（大概把相关的贴下）
<code> <button type="button" align="left" onclick="line()">查 询</button> <div id="container" style="width:850px;height:370px; float:left;"></div> <script type="text/javascript">function line() { if($("#account").val()==""){ Dialog,alert("请填写用户名！"); } else{ var x=[]; var y=[]; $.ajax({ type:"get", url:"<%=path%>/factor", data:{"eqid":$.trim($("#eid option:selected").val()), "acid":$.trim($("#account").val())}, dataType:"json", async:false, success:function(msg) { var returnValue = eval("("+msg+")"); for(var key in returnValue.rows){ returnValue.rows[key].y=returnValue.rows[key].consum; xtext=returnValue.rows[key].opt_time; } chart.series[0].setData(returnValue.rows.consum); }, error:function() { Dialog.alert("没有数据，请重新查询！"); return; } }); var chart=new Highcharts.Chart({ chart:{ renderto:'container', type:'spline' }, title:{text:'变化趋势'}, xAxis:{categories:xtext}, yAxis:{title:{text:变化趋势},}, series:[{name:"consum"}] }); };};</script></code>页面显示：
但是一直显示不出对应的图表，能否帮看下什么原因？
