Why does my lookup fields don't appear in visualize mode

Hello Everyone!

I created a lookup for match some of my original fields with others of a cvs file. When I go to the discover mode they appear but when I go the visualize mode and I want to make a table or some chart with them they don't appear.

Can I make charts or table with lookup fields?

Can you clarify what you mean by lookup field? The list of fields in visualize is a filtered down version of all fields, by the aggregatable response of the field capabilities api.
