I think you should be able to put the graph definition into
server/etc/hobbitgraph.cfg with a suitable name, then put that name into
both the "TEST2RRD" & "GRAPHS" environment variables in
server/etc/hobbitserver.cfg. Then send a suitable status message to xymon
and the graph shows up.
I've just tried this on my laptop: mash two existing graph definitions
together (cpu freq and battery capacity) into one called "batfreq". Add
"batfreq" to "TEST2RRD" & "GRAPHS". Send test message:
server/bin/bb localhost "status lorien.batfreq green `date`"
A short time later a new column shows up called batfreq. Clicking through
thre green dot shows a single graph containing both battery capacity and 2
cpu frequency lines (dual-core cpu).
In your case, I think you might be able to get the combined graph to show up
for each server by sending multiple status messages:
server/bin/bb localhost "status server1.xxx green `date`"
server/bin/bb localhost "status server2.xxx green `date`"
etc...
all from one script. Or just define a new server name in bb-hosts and send
one message. Either way, you'll probably want to have a regular status
message going to Xymon so that the new column doesn't go purple.

I created a small script that scrapes info from several hosts/rrd's
(connections to a particular IIS site) and puts it in a combined graph
(see attached sample). I'm curious if it's possible to somehow create a
"virtual host" in hobbit and use the hobbitgraph.cgi functions to create
the graphs so I can also have the zoom & history functions.
This is the script that created the attached graph:
