Just noticed today that the count shown is an aggregate of the total number of SSIDs provisioned over all APs.  I think this graph would be a lot more useful if it graphed the number of AP's per active SSID, or even the number of active SSID per AP.  The key here being 'active'.  I have one profile with ALL of my SSID's for testing and other reasons, but I only ever enable 1-3 of them at a time.  Everytime I apply this profile to a new AP, the count in the below graph jumps by 6 (total # of SSID in profile payload), not the two that are actually active.  I think the graph would be much more useful if it graphed the # of APs actively serving say the top 8 or 10 SSIDs, one colour for each SSID.
