[rrd-users] --width affects results?

[Gregory (Grisha) Trubetskoy]

Given the following script (rrdtool 1.2.11):

rrdtool graph /dev/null  --start=end-2592000  --width=500  \
     DEF:a=01-06-04-01.rrd:admin_uptime:AVERAGE  \
     DEF:b=01-06-04-02.rrd:admin_uptime:AVERAGE  \
     DEF:c=01-06-04-03.rrd:admin_uptime:AVERAGE  \
     CDEF:avg=a,b,+,c,+,3,/ \
     VDEF:tot_avg=avg,AVERAGE \
     PRINT:tot_avg:"average uptime %9.6lf"

rrdtool graph /dev/null  --start=end-2592000  \
     DEF:a=01-06-04-01.rrd:admin_uptime:AVERAGE  \
     DEF:b=01-06-04-02.rrd:admin_uptime:AVERAGE  \
     DEF:c=01-06-04-03.rrd:admin_uptime:AVERAGE  \
     CDEF:avg=a,b,+,c,+,3,/ \
     VDEF:tot_avg=avg,AVERAGE \
     PRINT:tot_avg:"average uptime %9.6lf"

I get the following output:

0x0
average uptime 99.988461
0x0
average uptime 99.988453

Note that the only thing different above is --width. Is this a feature or 
a bug? :-) Sorry, I didn't have time to research this further, just 
thought someone on the list might know right away.
