不推荐使用grid布局，不清楚为什么左边一列的不会自适应，换成flex布局就可以了

主要方法借助中的getInstanceByDom方法

完整代码：

<template><div class="statis"><div class="content" ><!-- v-for 遍历父级div--><div class="main" v-for="(item,index) in echartsData" :key="index"><!--自定义宽高的dom，用于放置图表--><div class="bar"></div><img class="title-bg" src="@/assets/img/title-bg.png"/></div></div></div>
</template>
