Yes, I did try that and that just gives a error and halts.  I gave a
bad example because if I use the set {"x", "y", "z"} like in the help
system, it prints "xNull", etc on the plot axes.  I have no clue what
is going on and I can't find anyone else who does either.  I guess I
need to call the folks at Wolfram for help, but I sure dread that
ordeal.
Thanks for trying to help.
