Hello,

Now, Maxima adds the following two lines to the Gnuplot script, when the user wants a green background, or any other color:

set obj 1 rectangle behind from screen 0.0,0.0 to screen 1.0,1.0
set style rectangle fillcolor rgb '#00ff00' fs solid 1.0 noborder

This solution works fine with most terminals, except with epslatex-standalone. It looks like the rectangle hides the latex text and axes tics.

This is a common header of the Gnuplot code automatically generated by Maxima:

set terminal epslatex standalone  color size 6.0cm, 5.0cm
set out 'maxima_out.tex'
set size 1.0, 1.0
set origin 0.0, 0.0
set obj 1 rectangle behind from screen 0.0,0.0 to screen 1.0,1.0
set style rectangle fillcolor rgb '#00ff00' fs solid 1.0 noborder
set size noratio
set xrange [-10.0:10.0]
set yrange [-0.99999443136554:0.9999969259539873]
set title ''
set xlabel '$2\pi$'
set ylabel ''

etc.

After executing the latex command on maxima_out.tex, we see the plot on a green background, but axes tics and xlabel are not there. If we remove the two lines cited above, we see the latex text and the plot, as it should be, on a white background. We are having problems trying to make background colors and latex live together.

Do you know of any work-around for this problem?

Thanks for your attention.
