Hi all!

I've got a map question. There are null values in my data that I can't seem to remove from my viz. Even though they are hidden on the map itself, they come up in the filter, which I don’t want. It looks like there used to be a way to remove those values through formatting (http://kb.tableausoftware.com/articles/knowledgebase/null-values) – how would I do it now?

(Apologies for the lack of attached workbook - my data is sensitive.)

Thanks,

Hilarie
