Is it possible to add an map of our region with the communinalities and fill the surfaces of each communinality according to report data?
Can I add it with a kml or shape file?
It is not possible to customize eazyBI app with custom maps in vector format.
Perhaps, the Dynamic map chart could be an alternative if your data contains the geographical data in it.
Please, find the example of how to create such a map:
