OK, now I understand your problem. It depends on what RRDtool version
you're using, but if it's the 1.2.x version then you do it like this in
graphs.cfg:

  FNPATTERN ^disk(.*).rrd
  DEF:p at RRDIDX@=@RRDFN@:pct:AVERAGE
  AREA:p at RRDIDX@#@COLOR@:@RRDPARAM@:@STACKIT@

The STACK keywork is deprecated in RRDtool 1.2.x, you do all of the
stacking with AREA definitions. The "@STACKIT@" thing adds the "STACK"
option for all datasets except the first.
