[Octave-bug-tracker] [bug #49223] gnuplot with -depslatexstandalone fails to produce axis labels

[Dan Sebald]

Follow-up Comment #23, bug #49223 (project octave):

I've tried your change.  I'm fine with it.  By not using the "backtext" group,
it simply relies on the order of drawing the PostScript elements.  There isn't
a way to fix this (hold on, I just had an idea...), and that is probably why I
stopped pursuing bug report https://savannah.gnu.org/bugs/?48200 .  In order
to maintain the desired order, we'd need the ability to

1) Render rectangular background (a postscript element)
2) Render axis annotation
3) Render the axis lines (postscript elements)

and the grouping I described (where all PostScript is bundled into one layer)
doesn't do that.

The one idea I just had (and it isn't the best) is if we could render the
background rectangle via LaTeX.  That's an easy rendering, as LaTeX can at
least draw rectangles pretty well (although most everything else in LaTeX
graphics is somewhat dodgy).  But, this too would require post-modification of
a file created by gnuplot.  Is it worth the effort?  Don't know.

BTW, it wouldn't be too difficult to write an Octave script equivalent of
"sed".
