Figured a way around this after finding the RPN man page (duh). If
anyone is curious, I used a couple CDEF lines to check if the value
pulled from the rrd exceeded a certain value and then an IF to push a
max value if so. This artificially caps the graph's max at a value
set by me.
$series =
"DEF:'bytes_in_raw'='${rrd_dir}/bytes_in.rrd':'sum':AVERAGE "
."CDEF:'bytes_in_gt_1GB'=1073741824,bytes_in_raw,GT "
."CDEF:'bytes_in'=bytes_in_gt_1GB,bytes_in_raw,1073741824,IF "
series is presented to rrdtool later in the script.
