创建容器

<div class="row margin-beauty">
    <div class="col-md-6">
        <div id="user_from" style="width: 90%;height:400px;">
        </div>
    </div>
</div>

<div class="row margin-beauty">
    <div class="col-md-12">
        <div class="margin-bottom-beauty top-select">
            <select id="user-select" class="form-control-erbi">
                <option value="day">日</option>
                <option value="week">周</option>

            </select>
        </div>
        <div id="user_num" style="width: 90%;height:400px;">
        </div>
    </div>
</div>
