Emit Filters functionality extended to Maps

[jharner-sp]

The Emitting Filters flag is a godsend but I was hoping to get further use from it, in my case I have a map that I'd like to be able to also use as a filter (which would be augmented by #13966 )

please elaborate your use case, what are you exactly trying to achieve in Explore and Dashboard for Country map chart. @jharding-blw

allow user to emit filtering event to other charts on dashboard by clicking on the map? or drilldown into the next level on map?

Allow the user to filter the dashboard via clicking on a state in the map. We have a lot of data spread across the US and using states to filter the rest of the dashboard allows ease of use by different departments given the customer's region/state.

Hi @junlincc yes cross filters are absolutely key. I come from alot of kibana use and boy it feels weird not to be able to click on a map state and emit a filter state=CA or similar.

Likewise not to be able to "comb" a time based visualization (e.g. click, select an area and release to create a time filter) Where could we discuss all these? (not just the map here). I think its a wider initiative to get the widget to their most interactive.

Thanks for considering!

Coming from PowerBI or other reporting tools this is something that I miss. I just begin with superset and when trying to create a dashboard with a map I realize that trying to reduce the information based on a map selection was not possible. This is something that makes the dashboard less powerful for analysis than those that you can create with other tools.

I think I have found a solution to this problem. It is necessary to add 3 new behaviors in the index file country map in the metadata object

In this case, it is necessary to add some logic using setDataMask when you click on a region
