1. I'm having a some trouble replicating this problem on a recent
gnuplot download,
and I'm wondering if the gretl version of gnuplot (for Windows) compiles
in support
for pngcairo and if that takes over as the PNG backend for the gretl
version?
(If I use a downloaded gretl, the PNG back end does not give me the problem,
but if I change pngcairo to png I still get the problem with gretl.)
2. Just out of curiosity, how did you get the help to work in gretl's
gnuplot
(I'm on Vista), and is that something you could give back to gnuplot?
