I have two histograms. Together they tell one story, so I want to put them in one figure. I want to stick to one column format, therefore I want them vertically. How can I do that?
I've only seen answers on how to put them next to each other horizentally.
EDIT: turns out that I can simply repeat \includegraphics twice and that's it!! Okay, so how can I put sub-label for each one? like (a) and (b) ?? so that I can talk about them in the caption?
