Plotting questions: changes in plotting between 5.9.1 and 5.9.2

Hi Mario,

Thanks for your quick response and the demo.  It seems to work well, I
expect I will now be able to do everything I want to do.

By the way, after reading your message I've found that the
maxout.gnuplot file is now ending up in my home directory ~ instead of
my working directory, as it has in 5.9.1.  

Cheers,

Pete
