Comparing Achievement Graphs

I want the option to disable the GB crew achievement graphs, and I want to be able to replace the GB crew graphs with other people on GB that I follow.  However, to avoid creating graphs with hundreds of GB member's achievement progress, maybe there could be a limit to 5 or something.  Sound good?

Also I want the graph to be able to go back more than 30 days, maybe even have an all-time graph.
