You could make it suitable :-)
What I've done in the past is to stash the raw data away into some other
storage mechanism (e.g. a MySQL database). Then, when I want to put the
graphs together, export the data as XML and run it through rrdrestore to
create a rrd file crafted for purpose...
There are probably cleaner ways to do this, but it got me out of trouble :-)
