We've had good luck with using NCV to add graphs. The pix template that I've 
recently submitted is designed so that the message is formatted with that in 
mind. The downside is that it does require you to edit hobbitgraph.cfg and 
hobbitserver.cfg in order to add the NCV configuration options. On the positive 
side, once you've worked out a couple of these it's not too hard to remember how.
