Hello guys, I have a little problem, in my Odoo reports (in graph and pivot view) the measures dropdown shows me a lot of fields, but I'd like only show a specific fields because other ones are fields that I'm using for internal calculations, but I don't know how remove or hide this fields.

Could help me? Thanks!!
