Yes, but those are graphs of the same type (disk). What you're after are
combining graphs of different types (cpu, vmstat, memory). The way the
current graphs code is structured makes that difficult.

It's a bit more complex than that :-)

The lib/hobbitrrd.c file is right - you should look at the 
hobbit_graph_text() routine, which is the one that generates the
HTML links to the graph images. But it's currently pretty much tied
into generating one graph at a time.
