   **TITLE**
   
   [Feature] Can visualMap provide selectData interface?
   
   **BODY**
   
   ### What proplem does this feature solver?
   
   When you encounter a need to display two thermal maps on the page: First of all, when you click on one chart, the corresponding elements in another chart need to be highlighted. Selected element update selection status.
   
   I have tried to use Connect and monitor Hover to change the high bright state through Dispactch, but these two methods can only change the state of the Chinese block in the combination of the heat map, and cannot change the state of VisualMap's state
   
   After consulting the relevant documentation, it was found that VisualMap only provided [SelectData Manage](https://echarts.apache.org/API.html#ACTION.VISELECTDARAPARAPE) event interface. This can only change the range and cannot change the selection state. After checking the source code, I found that VisualMap updates the selected state by monitoring the MouseHover event, so I cannot update the state by changing the highlight state of the second table.
   
   I think this is an interface with a high demand, which can greatly improve the interaction of ECharts.
   
   ### What does the proposed api look like?
   
   Maybe you can add interfaces such as `selectdata` to VisualMap: you can update the VisualMap selected status through the data selected by MouseHover. Or add an Option or judgment rule to VisualMap: you can update the status by listening to the high -brightness of the highlight state
