The end game graphs, or at least the ones on the web, should have a game time slider so players can see all the usual end game stats at various points in the match. This will help players understand how effective there early game runes, decisions and play styles are. There is information to be had from the graphs at points in the game other than the very end that i want to see.
This will help answer questions like "is scorch really doing that much by the 10 minute mark?" or "is this early item paying off as much as i was hoping?" and "how big is my 2 item power spike really?"
