这个是前段时间做的一个项目模块，实现内容是调查问卷，如：
1：你的性别？
2：你的年龄？
。。。。。。
后台根据提交的内容，通过图表显示比例出来
废话就不说了，贴上代码：
注意，我项目是mvc框架
前台代码：
<strong><span style="font-size:14px;"><div class="panel-body">
<table width="100%" class="table-hover">
<tbody>
@if (Model != null && Model.Any())
{
var i = 0;
foreach (var kvp in Model)
{
i++;
<tr>
<td>
<div class="row">
<div class="col-md-6">
<section class="panel">
<header class="panel-heading"> 问题 @i：@kvp.Value </header>
<!--图表-->
<div class="panel-body">
<div <span style="color:#ff0000;">id='[email protected]' class="pieChart" </span>qname="@kvp.Value" qid="@kvp.Key"></div>
</div>
</section>
</div>
<div class="col-md-6">
<section class="panel">
<!--图表-->
<header class="panel-heading"> <span class="tools pull-right"> <a class="fa fa-chevron-down" href="javascript:;"></a> <a class="fa fa-cog" href="javascript:;"></a> <a class="glyphicon glyphicon-dashboard" href="javascript:;"></a> </span> </header>
<div class="panel-body">
<div <span style="color:#ff0000;">id='[email protected]' class="pillarChart"</span> qname="@kvp.Value" qid="@kvp.Key"></div>
</div>
</section>
</div>
</div>
</td>
</tr>
}
@Html.Hidden("pid", (int)ViewBag.ProId)
}
else
{
<tr><td>当前结果分析还未有数据！</td></tr>
}
</tbody>
</table>
</div></span></strong>
大家要注意我红色标记的地方，是关键的地方，
js代码：
<strong><span style="font-size:14px;"> <!--图表highcharts-->

后台方法：后台注意是返回生成图表的格式数据
