Further thoughts. I checked the current gretl release, 2019a, on a Macbook Air running Yosemite (OS X 10.10.5). Plotting went fine and the packaged gnuplot is version 5.2.4, so "too old" does not apply. That leaves "broken"... I guess it's possible that an OS X system update removed a library that gretl's gnuplot needs. You could check for this by opening a Terminal window (under Applications/Utilities in the Finder) and executing the following command: /Applications/Gretl.app/Contents/Resources/bin/gnuplot.sh If gnuplot can't start then hopefully there will an error message that gives us a clue. One other thing: In gretl you could go to Tools/Preferences/General and the Programs tab, and see what's entered for "Command to launch gnuplot". The entry should either be just "gnuplot", or else "/Applications/Gretl.app/Contents/Resources/bin/gnuplot" -- anything else is likely to cause gretl plotting to fail. Allin
