How to make points on the map do not disappear?

[Anonymous]

I have a map with some locations, each location has location type (for example location types: "X", "Y", "Z"). When i click on a location in the table below map only one point remain on the map. I want to see on the map filtered point and all points which has location type "X". Is this possible?

@Anonymous , Try a measure like

meausre =

var _loc = maxx(allselected(Table), Table[LocationType])

return

calculate(Count(Table[Value]), filter(all(Table), Table[LocationType] = _loc))
