Trick to change octave's plot background

Well, I was trying to change octave's plot background, but I found no easy way, so I changed the way gnuplot is called (gnuplot is the program octave calls to plot the graphics). Simply go to /usr/bin, log as root, and backup gnuplot as

cp gnuplot gnuplot.bak

Rename it to gnuplot1:

mv gnuplot gnuplot1

Now create the script gnuplot by typing

emacs gnuplot

Create this script:

#!/bin/bash
/usr/bin/gnuplot1 -background white

Add execution permission through chmod +x gnuplot

It will make a standard call to gnuplot change to gnuplot -background white, which will change your plots background in octave.
If you have a better way to do this, please leave me a comment
Have fun :)
