Hi,

As far as i know, you can have only one graph illustrating a test.
But you can define in your hobbitgraph.cfg several graphs using your 
rrd files. So you could define like this :

[lun]
FNPATTERN lun(.*).rrd
TITLE LUNs IOPS
YAXIS IOPS
DEF:p (at) RRDIDX@= (at) RRDFN@:lambda:AVERAGE
LINE2:p (at) RRDIDX@# (at) COLOR@:@RRDPARAM@
GPRINT:p (at) RRDIDX@:LAST: \: %5.1lf (cur)
GPRINT:p (at) RRDIDX@:MAX: \: %5.1lf (max)
GPRINT:p (at) RRDIDX@:MIN: \: %5.1lf (min)
GPRINT:p (at) RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

[lun1]
FNPATTERN lun1(.*).rrd
TITLE LUN1 IOPS
YAXIS IOPS
...

then you could define in your hobbitserver.cfg :
GRAPHS="...,lun1,lun2,..."

and finally in bb-hosts :
host IP.AD.DR.ESS # TRENDS:*,lun1,lun2...

So, you'll have a graph dedicated for "lun" column, including all IOPS 
(maybe you could format your test's output to get comprehensive name as 
"Read_lun1").
And in "trend" column, you'll get separated graphs
If I misunderstood your request, please add following details :
-your script output format
-your actual [lunX] definitions in hobbitgraph.cfg, and SPLITNCV 
definitions for lun* in hobbitserver.cfg

Hope this helps
