Thank you!
For gnuplot your suggestion worked perfectly. I have now tweaked /usr/share/gnuplot/5.4/gnuplotrc as required.
Perplexed by your "vim not vi". I set up my Cygwin platform using setup -P and do not specify any editor beyond nano
(which is perfect to my needs). Nevertheless I get vi. From "Package search" I'm guessing it comes as an adjunct because I also need
groff and latex. You must actually specify vim? which I vaguely recall preferring to vi but cannot remember why.
(Mainly, I  liked neither. But I can remember easily setting and locating /etc/vimrc, and that it was properly picked up.)
Nevertheless, still having problems with setting and location virc - since I've got vi, I'd just like to be able to use it effectively .. ..
Thanks again, anyway.
