Is it posible to use field filters in simple questions or only in native query questions?

I don't know how to add field filters to simple questions in order to link them with a category in a Dashboard. I'm able to do it for native SQL questions, but not for pie graphs generated by simple questions.

Also in my dashbord when trying to link, for example a pie chart generated through a simple question I only get 3 options to filter and I'm not sure why only those 3, is there a way to add more ?

Thanks I would really appreciate your help

Hi @Maritrini
Make sure that the Field Type in Admin > Data Model is set to "Category" for the column, then you'll be able to connect a filter.

Maybe this helps:
