Seems that it should also be allowedShapes: [ 'continuous' ], ?

I think this would affect the map supporting histograms too. I have not been able to find an integer ordinal variable for a mappable study, however.

Shouldn't we just change the histogram constraints in service-eda to only allow shape=continuous, @d-callan ?
