I know, I know. It's amazing how many times I broke this rule. I do better in future.

Somehow I think there should be a different design rules for labeling "persistent" (?) graphs, i.e. graphs that you look at regularly. If you look at a graph couple times a day you need to know the meaning of axes only one time. After that, the labels are waste of the real estate. I will look at the vital signs equipment to see how it's done.

The point of labelling graphs, much like commenting code, is communication with others and your future self.

This is invaluable comment. Changes my whole perspective on how to represent the data. If I could I would use all my karma here. Thank you

EDIT: My mentor always says "graph or table has to stand on it's own" but that does not resonate with me. The "commenting code" analogy does.

I still don't know what does the vertical axis represent. Normalized points? At what time?
