RRDtool knows about PRINT, withouth a G, and then prints to stdout.

You have bytes per second in your RRD.  If the average rate per second is, 
say, 1GB/s, then on average 1GB was transfered every second.  Thats 86400 GB 
in a day, 7*86400 GB in a week, and so on. Just multiply the average rate by 
the amount of time on the X-axis.

Printing the average rate using RRDtool is easy.  Multiplying by the amount 
of time you're interested in can be done inside or outside RRDtool.

Printing the 95th percentile is only slightly harder.

See the (online) docs, the tutorial, or this:
