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）
<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>
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？
