map+echart+vue 大数据多次渲染卡顿问题
尤其是地图组件比较庞大，再导入大批量数据最容易造成卡顿的出现。
尤其是渲染次数多，交互多的情况。
所以每次重新加载数据一定要先销毁之前的。
不然越越卡直到卡死
父组件：
<div class="mapchart">
<amap :key="mapkey" ref='mymap'></amap>
</div>
chosethismaptab(ind){ // 每次重新交互接受新数据
this.tabind = ind
this.$refs.mymap.destr() // 每次重新加载 通知子组件先销毁再渲染
this.mapkey+=1
},
子组件
destr(){ this.myChart.dispose(); },
这样就不会再卡顿了，不管怎么交互，点击多少次重新渲染都没问题了。
卡顿容易造成渲染等待越来越长：
不卡顿状态：
就算下钻再深也没关系
