Thank you for the explanation and your patience in answering me this
obviously very simple question!!

Originally I tried to store plots directly in a list. So writing them
directly to disc was just a good alternative. I knew that that jpeg()
provides functionality for that, but didn't use it correctly.

Hence, is it also possible to store a plot in a list, somehow?
