lib/Orca/Contstants.pm does not have to be changed.  The hourly graphs now 
show the 1 minute data elements graphed.  RRDs are now setup for a "step" 
value of 60 seconds:

<soneill at chivas:16>$ /usr/local/orca/bin/rrdtool info gauge_trap.rrd
filename = "gauge_trap.rrd"
rrd_version = "0001"
step = 60
last_update = 1029772684
<SNIP>

I found in the lib/Orca/RRDFile.pm the code allowing this step value to be 
changed based on the interval value from the config file (with some 
somewhat funky math LOL) - sweet :)
