I have a map-based visual that supports spatial filtering. Currently, if I draw a spatial filter, the points within the filter are added to the current selection, and other visuals are properly cross-filtered.
The problem is if my spatial filter returns no points. If I clear the selection set, all values are displayed in the other visuals. Is there a way I can manipulate the current selection so that no records are displayed in the other visuals? Maybe a "null" selection id that references no existing record?
