[GitHub] [echarts] helgasoft commented on issue #6259: brush 功能除了多个图放在一个对象内用 brushLink 进行绑定，是否有 API 可以支持主图上框选后在其他选择特定的点进行显示？

   Renewing this request for enhancement.  
   Looks like currently (v.5) there are *action* equivalents [brush](https://echarts.apache.org/en/api.html#action.brush.brush) and [brushEnd](https://echarts.apache.org/en/api.html#action.brush.brushEnd) for *events* [brush](https://echarts.apache.org/en/api.html#events.brush) and [brushEnd](https://echarts.apache.org/en/api.html#events.brushEnd), but **no action brushselected** for event [brushselected](https://echarts.apache.org/en/api.html#events.brushselected).  
   It would be helpful to have it with similar format:
   ```
   chart.dispatchAction({ 
      type: 'brushselected', 
      selection: [ 
             { seriesIndex: number,  dataIndex: [] },
             { seriesIndex: 0,  dataIndex: [1,2,3,5] } 
      ] 
   });
   ````
