I am running gnuplot 5.0, patchlevel 6. The link to Octave was just because that was the place I found that talked about the line length problem in gnuplot.

The error (when I got it) looked like my plot command line had ended prematurely, and gnuplot was expecting another argument. But since the problem went away I can't cite the error exactly.

I knew about reset, and had that. But not about utf8, I will put that in. Thanks for advice. And I should have known to try restarting.
