Can we get some more detailed end-game statistics graphs?

OK, so I haven't been playing league for very long, but I feel like it would helpful for me if the end-game stat graphs were two-dimensional over the period of the entire game, so that say when you look at champion damage you could look at how much total champion damage you had dealt by say 10 minutes, 20 minutes, etc. Different champs scale differently and shine at different points in the game, where say mages do more damage mid game and carries do most of their damage late game. If this were reflected in the end-game stats it would be much easier to judge performance throughout the game. It could also have marks along the graph which tell you when you got a kill, assist, or died.

Anyone with me on this? I can't imagine that it would be that difficult to implement. I know that when I played WoW the combat log keeps track of every proc of damage, which can be directly accessed by an add-on that could plot these over time. I feel it would be much more useful than the current one-dimensional total damages that you get at the end of the game, which don't necessarily tell you all that much about performance over the course of the game. Just an idea.
