Who I have the same questioned this topic

Has anyone come up with a way to view data usage in a graph format? Maby by the hour? Would like to see what uses data most and when. For example, when my wife leaves computer on and walks awat for hours, with spotify still playing; or when grandkids are playing games, etc.

The detailed view dosen't tell me enough. We regularly excede the 10 gb. I want to know where to cut.
