I thought you could do it via several calls to hobbitgraph? For example 
I have a host that has many disk partitions. If I don't want to see them 
all on a single graph, I can select just the first partition via the 
"first" and "count" options:
https://www.myhost.com/hobbit-cgi/hobbitgraph.sh?host=myhost&service=disk&graph_width=576&graph_height=120&first=1&count=1&disp=my%2dhost
This gives me a graph with only that data element.
I can get a graph of only the 2nd via first=2&count=1, or elements 5-8, 
first=5&count=3.

Not the optimal way to do it, but it should work for creating a graph 
external to Hobbit, which won't have it built in as its own column the 
way you want, but you could always make calls into hobbitgraph from 
another html page.
