   我看了下echarts源码找到了一种新的解决办法，就是使用batch方式，这样可以使用到escapeConnect属性
   ![image](https://user-images.githubusercontent.com/26249572/112801390-6b591000-90a3-11eb-809d-4391dbaec9e7.png)
   ``` 
   chartInstance.dispatchAction({
     type: 'legendUnSelect',
     escapeConnect: true,
     batch: [
       {
         name: key,
         selected: legendsSelected,
       },
     ],
   });
   ```
