gnuplot v5. IMHO yet another reason to push for the switch.
The situation on Ubuntu appears better than I thought:
"gnuplot5
vivid (math): version 5 [universe] 5.0.0~rc+dfsg2-1: all
wily (math): version 5 [universe] 5.0.1+dfsg1-3: all
xenial (math): version 5 [universe] 5.0.3+dfsg2-1: all
"
As 'vivid' is 15.04, next month it will be one year when gnuplot 5 is easily
available. Version 16.04 will be a LTS release for those people that do not
want to upgrade often (which I absolutely understand). I also understand that
people wait a month or two before upgrading their distro, but IMHO switching
to gnuplot 5 for gretl in June 2016 would not be a major problem. (A minor
problem it would be anyway I guess, since things have to be adjusted of
course.)
Or better still: since we have already an internal function to establish
the gnuplot version at runtime, we could have a "dashtype" GUI item that
is activated iff the gnuplot version the user has is 5.0 or above.
This would be totally ok for win and Mac people, and would leave the
burden of upgrading only on linux guys who can either (i) upgrade by hand
or (ii) wait for their distro of choice to do so or (iii) change distro
