echarts生成柱状图

1、引用js

<script src="${ctxStatic }/echarts-3.6.1/echarts.min.js">script>

2、

<div class="container-fluid"
    style="padding: 0px; background-color: #fff;">
    <div class="row-fluid" style="padding: 0px;">
        <div class="col-md-12" style="padding: 30px 10px 0px 10px;">
            <div id="main" class="main alert"
                style="width: 100%; background-color: #fff; height: 420px;">div>
        div>
    div>
div>

<script type="text/javascript">
    $(document).ready(function() {
        showZZT();
    });

    //生成柜状图
    function showZZT() {
        $.ajax({
            url : '${ctx}/cms/statCmsWebstat/createEcharForBar',// 跳转到 action  
            data : {
                "phase" : $("#phase option:selected").val(),
                "startYear" : $("#startYear option:selected").val(),
                "year" : $("#year option:selected").val(),
                "startMonth" : $("#startMonth option:selected").val(),
                "month" : $("#month option:selected").val()
            },
            dataType : 'text',
            type : 'post',
            success : function(data) {
                if (data == "") {
                    $("#main").hide();
                } else {
                    $("#main").show();
                    eval(data);
                }
            },
            error : function() {
                layer.alert("数据绑定异常！");
            }
        });
