Hi,

What do you want, exactly ?
For information, SPLITNCV (and NCV too) needs a pre-formated output :
NAME1: VALUE1
NAME2: VALUE2
You need a new line character at this end of your output (don't ask me 
why...)
You can use NAME= VALUE instead of NAME: VALUE.

An advice, if your script sends data in the right format, you can use
SPLITNCV_test=*:GAUGE
it allows to get any value stored in RRD file.

In hobbitgraphs.cfg, you can use the following syntax :
[test]
       TITLE My I/O test
       YAXIS I/O per second
       FNPATTERN test,(.*).rrd
       DEF:@RRDIDX (at) =@RRDFN@:lambda:AVERAGE
       LINE2:@RRDIDX (at) #@COLOR@:@RRDPARAM@
       GPRINT:@RRDIDX@:LAST: \: %5.1lf (cur)
       GPRINT:@RRDIDX@:MAX: \: %5.1lf (max)
       GPRINT:@RRDIDX@:MIN: \: %5.1lf (min)
       GPRINT:@RRDIDX@:AVERAGE: \: %5.1lf (avg)\n


I hope it could help you.
I think it could be usefull to know what you exactly want for final 
result. (multiple graphs, one graph with multiple lines...)
