Version of Octave?

Version of gnuplot?

I'd be happy to have a patch that fixes this problem and doesn't break
other cases that have been discussed in the past:

But in any case, I suspect we will have these kinds of problems until
gnuplot is fixed, or we use something else for rendering graphics that
doesn't require using text formats for sending data for things like
text label locations.
