If there is a error in your script and you use "gnuplot scriptname" from
the shell then you see often nothing.

From inside gnuplot, have first open gnuplot, you must use the following:

gnuplot> load 'scriptname'

There must be some quotes at the scriptname (' or ").

If there is an error in your script, or gnuplot can't find your script,
you get an error message. See "gnuplot> help load"
