A really old post but, as I could find anywhere better, I thought I would add some details from experimenting here (I haven't done much, but at least one bit seems new):
Beyond the Eye views, the Status and the State summary there are 6 windows available:
Bit Allocation - Bitloading in a one histogram bar per tone
Gi Allocation (Gain) - The gain applied to each tone. My guess is in a perfect line this would be a straight line
SNR - Signal to Noise Ratio (contains Minimum and maximum as well as current
Showtime Margin - the Margin for each tone at the point of synchronisation
Channel Response - The HLog
Quiet Line Noise - Also shows Minimum and maximum when shown during the QLN Monitoring (from the tests menu)
