Yeah, I know the languages of Spain, I'm spanish myself. The point is, neither do asturians nor galicians identify themselves other than Spanish, maybe they do identify themselves as galician and spanish. Some part of catalan and vasque people do identify themselves as catalan or vasque and not as spanish, but they're not a majority of the population.
Something than happens here is that people tend to identify themselves with their region and then spanish (let's say, andalusian and spanish, or valencian and spanish), it's complicated to explain, but my main point is that if you're gonna take into account how people identify themselves, you might only show the Basque Country and Catalonia, as they're the only regions with an important number of people not identifying as Spanish. I hope my explanation was somewhat understandable huh
Also, the language of Asturias is called "Asturleonese", as it is spoken in Asturias and the north of León, thus if you are going to mark León too, make sure you include them in the same group as asturians. And about aragonese...it is mainly a nearly extinct language, I think only 15.000 people or so speak it, as it is being totally assimilated by Spanish, and the feeling of being another group instead of being spanish is nearly non-existent.
Spain is, to be honest, a big mess in this aspect.
