Hello , 
I just saw this topic, I am making a gnuplot script and want to know-
How do we invoke the gnuplot script ?
I am working with the following script below..
Do we have to keep a filename extension for using the script ?
""
set terminal pdf
set output "myplot.pdf"
set contour
set view map
unset surface
set cntrparam levels discrete 2.3,6.2,11.8
splot [0:360][0:0.9] "test1.dat" with lines
""

Thank you.
