 Not sure what you mean by "from sourceforge", 
I mean from here:
https://sourceforge.net/projects/gnuplot/files/gnuplot/5.2.8/
 but I've just verified that replacing the wgnuplot.exe in the
snapshot 
 installation directory indeed fixes the problem. 
Ah, excellent.
 Here's a step-by-step 
 guide for Windows users - this should work also for gretl 2020b and 
 perhaps even older versions:
 1. Download 
http://ricardo.ecn.wfu.edu/pub/gretl/winbuild/gp524w64.tar.gz
 Remarks: Despite the file name AFAICS this contains gnuplot 5.2.6, not
 5.2.4, which is good. If you run 32bit Windows you must download
 gp524w32.tar.gz instead. (Haven't tested the latter.) Perhaps those
 files will be renamed in the future to ...526... or ...528...
 2. unpack/extract that archive (first to tar, then to a new folder); on
 Windows I use 7zip for that.
 3. Copy the contained files wgnuplot.exe, wgnuplot.mnu, wgnuplot.chm to
 the place where gretl is installed. On a default install this should be
 "C:\Program Files\gretl". This will overwrite the existing versions of
 those files; you need admin access rights to do that. Perhaps you want
 to make a backup of the old file versions, just in case.
 This should hopefully be it. It's probably a good idea to restart gretl. 
Thanks, Sven!
