Signs on graphs to denote "Lower is better" or "Higher is better"

I was wondering if some signs (like ▲▼) would help read the data that is collected instead of pure bar charts. For example waking up too many times per night is a bad sign (AFAIK) so it might help to read all the data better if a down symbol would be next to the data label or something.
