Could you add a feature to exclude certain directories from the recursive directory scan?
Also if too many different results then it looks all scrunched up is their a way to get it to still show all of the graph but not scrunched up without limiting the graph to the top whatever.
Here is a couple of my graphs also. First one is by genre and only if it was over 10 songs as from where I got a compilation cd their is several with only a couple and such. Second is by year and if I remember correctly it is all years.
