Any of our existing .rrd files seem to present the symptom.

Here's a sample command-line:

rm -f *.png; strace -o log /usr/bin/rrdtool graph t1_lav.png -a PNG -o 'DEF:ops_ave=/var/log/mta/tidymail/1/rrd/lav.rrd:data:AVERAGE' 'CDEF:foo=ops_ave,ABS' 'LINE1:foo#0000ff'

Remove that "-o", for a linear y-axis, and it works.
