Show Lines For Any User

Is there a way to show lines for any user? The top 5 is nice, but it doesnt it restricts in the fact that one of the top 5 has been gone for months, so its just top 4 of 5. 

So a url path of git_stats/authors/mike_rivera/changed_lines_by_author_by_date.html or something would be awesome.

If there isn't a way and you dont have a chance soon, I'd look into it if you give me a starting point or two in your code base. 

Thanks, 
Mike
