I am trying to represent data points in different performance categories for schools over a two year period. One school has a N/A data point for year 1 because it didn't exist.
When I build my dashboard, "Null" appears at the top. I'd like to get rid of Null from my filter, but still be able to see year #2's data point for that school if it is selected.
I think Null is appearing because of this 1 school.
