[evince] Display output from gnuplot

[chuck adams <chuck adams k7qo gmail com>]

I have the simple test case for ubuntu 11.04 distribution:

graph.gp file
-----------------------------------------------------
set terminal postscript enhanced
set output "graph.ps"
set logscale y
set xrange [0.0:90.0]
set yrange [0.001:1.000]
set xlabel "Zenith Angle [degrees]"
set ylabel "Transmitted Radiance"
plot [0.0:90.0] "001.data" using 1:2 title "{/Symbol t}=0.05" smooth
csplines
-----------------------------------------------------

001.data file

Hope this helps and I hope that it is not my error.
With the first two lines removed from the graph.gp
file, the gnuplot program works as advertised and
with the two lines in the graph.ps output file 
shows to be postscript.

thanks in advance,
