Some games (i.e. Civ 5) at the end show you not only cumulative stats, but also how they changed during your game in the form of graphs.
I thought it'd be cool to see how my influence changed over time or where my 'damage dealt' spiked and by how much, etc.
PS. I believe that currently Cogmind tracks only the max numbers or the sums, so it can print them in the scoresheets. Graphs would require saving stats in regular intervals (i.e. every 100 turns it saves my influence (average over 100 turns), how much damage I dealt in those 100 turns, ...). Or, rather than choosing an arbitrary number of turns, you could dynamically adapt the interval length, so that all runs have, say, 100-200 data points.
