We are using the map visual and we are seeing some peculiar behaviour for this visual.
I have the data like this, whenerin the first level of hierarchy is the Country and the next level in City. For the City column I have already appended the country so that when only City is plotted there is no discrepency for the same name cities across globe.
Now coming to the problem, we are able to plot properly and the "Drill" mode and "Go to the next level of hierarchy" works absolutely fine. Problem comes in with we use "Expand All down one level in the hierarchy". The data just disappear! It dosen't show anything.
This how it looks when we see at City level (using the "Go to the next level of hierarchy")
Same data when converted to other visual like bar chart gives me proper information.
My ask is, is there any limitation with repect to Expand All feature while using map?
