Custom Graph

One other thing is, it's possible there may be something funky going on with
whitespace in the hobbitgraph.cfg file.  I've had this happen once or
twice.  To correct it, I completely deleted the entries I made, and manually
typed the graph definition back in, character-by-character.  Since your
graph definitions are short enough, it won't take much time to try.  Also,
enter in only one, save, and see if that helps.
