Re: problems of gnuplot 5.4 when pipng commands from python

You are operating on Windows 10?
I had hoped you would get a response from someone more familiar with
Windows than I am, but it seems rather quiet here lately.

My understanding is that this is a known problem when combining specifically
gnuplot version 5.4 and Windows version 10.

Issue tracker here
   https://sourceforge.net/p/gnuplot/bugs/2412/

There is a suggestion there that reverting commit 651af626
may fix the problem, or at least return it to the same behavior
as gnuplot 5.2.   If you are able to build gnuplot from the
git source and confirm that reverting that commit works, that
would be very useful information.

    best,
