Hi,

For your question about multiple items on one graph, you can do the 
followin instructions (from hobbitgraphs.cfg)

# For graphs that use multiple RRD files as input, you specify a filename
# pattern in the FNPATTERN statement, and optionally a pattern of files
# to exclude from the graph with EXFNPATTERN (see "[tcp]" for an example).
# When FNPATTERN is used, you can use "@RRDFN@" in the RRDtool definitions
# to pick up each filename. "@RRDIDX@" is an index (starting at 0) for each
# file in the set. "@RRDPARAM@" contains the first word extracted from the
# pattern of files (see e.g. "[memory]" how this is used). "@COLOR@" picks
# a new color for each graph automatically.

So, all you need is to have items in separates RRD files, using 
SPLITNCV_test instead of NCV_test in hobbitserver.cfg file.
Then follow the instructions.
My running configuration for this kind of graph (multiple items in 1 
graph) is :

[hardware]
TITLE Temperatures
        YAXIS Celsius
        FNPATTERN hardware,(.*)_temperature.rrd
        DEF:@RRDIDX@=@RRDFN@:lambda:AVERAGE
        LINE2:@RRDIDX@#@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
