Try this:

cp file.rrd file.rrd.bkup (backup the file)
rrdtool tune file.rrd
rrdtool tune file.rrd --data-source-type dsname:DERIVE
rrdtool tune file.rrd --minimum dsname:0 --maximum dsname:100000000
(100000000 is an example...)
rrdtool tune file.rrd
rrdtool dump file.rrd > file.xml
rrdtool restore --range-check file.xml file.rrd.new

You can also change you graph file (.sh or .pl)
you have something like:
'DEF:A=/path/to/your/file.rrd:dsname:AVERAGE'
then you graph it with LINE1:A#.... or so
You try this
'CDEF:B=A,MINVALUE,GT,A,MAXVALUE,LT,A,UNKN,IF,UNKN,IF' then graph B...
replace MINVALUE with the minimun value you want to graph (ex: 0) and
MAXVALUE with the maximum value you want to graph (ex: 100000000)
