I think you can't do this if you are using gnuplot 3.7.3 or below. But
gnuplot do have a new version for 'fill' function. You can download the 
new version and use the following script to implement the fill between two
lines.

set xr [0:5]
set yr [0:20]
plot x+5 w filledcurve y1=5
pause -1

You can find the newest download at:
http://sourceforge.net/projects/gnuplot/


Good luck

Ding
