"virtual hosts" for combined graphs?

[Walter van Loon]

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:

#!/bin/bash

timestamp=COMMENT:Updated\\:`date|sed 's/:/\\\\:/g'`
