Fill plot area with background color

[Harald H. <h.h...@tu...>]

Is there a way to fill the plot area with a background color?
What I mean is similar to this example:

set terminal postscript eps color rounded linewidth 2
set output 'asdf.eps'
set style line 1 lt 1 lw 4
set style line 9999 lt 6 lw 1
set style fill solid 1
plot 1 with filledcurves above y1=-1 ls 9999,\
     sin(x) ls 1

Unfortunately, the tics are lost here. In my company, most plots are
filled by a yellow background (it does not matter if I like it). Now the
question is if I should programme a patch that provides something like

set backgroundcolor graph #rgb screen #rgb

or if there already is a possibility to reach that.

Greetings
Harald
