The average is multiplied by the total amount of seconds on the graph.

However, in your case most of the graph is *unknown* data and the average
function discards the unknowns.  This normally isn't a problem but in
this extreme case it is.

If you do the same for '20020330 00:00' to '20020403 00:00' and multiply
by 4*86400, it should be closer to what you expect to see.

Hmmm...  this *used* to work.  Are you sure it doesn't anymore?

Note to others: This is for 1.1.x, not for 1.0.35
   DEF:In=/etc/rc.d/192.168.0.2.rrd:input:AVERAGE
   DEF:Out=/etc/rc.d/192.168.0.2.rrd:output:AVERAGE
   VDEF:totalIn=In,TOTAL
   VDEF:totalOut=Out,TOTAL
   GPRINT:totalIn:"%6.2lf %sB"
            (yes, no CF in here)
   GPRINT:totalOut:"%6.2lf %sB"
