It's really great that you are working on this.  Don't forget to add
yourself to CREDITS.txt :-)

The change seems reasonable.

I strongly suspect that the problems shown below are caused by changes
to gnuplot itself.  Several gnuplot commands and options have changed or
been marked deprecated, and Gnuplot.py hasn't been brought up to date.

Of course it would be nice to bring Gnuplot.py up to date with the
current status of gnuplot, but certainly not at the risk of your energy
running out and no release being made at all!
