Not entirely on topic but since you're talking about last here it
is anyway:

I'm considering implementing FIRST inside rrdtool graph.

I'm working on an extention to rrd_graph.  This allows for fetching
values from a DEF statement, such as min,max,average,percentile,
last and first.  More to come (probably).  These values can be used
inside (G)PRINT but can also be used in CDEF statements.  Eventually
everything should be programmable.

What about:

DEF:inbytes= ... 
GPRINT:gm:"Max. %6.2lf %sBps"
GPRINT:ga:"Avg. %6.2lf %sBps\n"
HRULE:gp#FF0000:"95th percentile"
GPRINT:gp:"%6.2lf %sBps"
GPRINT:bill:"USD %6.2lf"
TITLE:"traffic from foo to bar\nstart %c end %c, cost %9.2lf",gs,ge,bill
