VUE根据数组生成多个echarts图

效果图：

 

 

 

 

 HTML代码：

<div class="chart-dis-area" style="display: flex; background-color:#0B1837 ;">
　　<div v-for="(item,index) in chartList" class="chart-item-area" style="width: 20%;">
　　　　<div class="echartsList" :id="item.id" style="height: 225px;"></div>
　　</div>
</div>
