Instead of resetting all these things, I simply added a call to
oneplot in the figure function.

The problem with using an M-file to handle resetting the state of the
external gnuplot process is that you can't be sure what the default
values should be.

I believe recent versions of gnuplot do have a reset function, so it
would not be too hard to write a greset function that runs the gnuplot
reset command.  However, doing that doesn't seem quite right to me
either, because the gnuplot reset command appears to set the values of
the gnuplot variables to some internal defaults, ignoring any personal
defaults that might be set in a ~/.gnuplot file.  (Besides that, the
reset command seems to make my copy of gnuplot (3.6b319) crash...)
