A number of different things are being tried.  The following Perl program 
looks like it will produce good results for sending commands to Gnuplot. 
This code is based on some code that was found in the Gnuplot Questions
and 
Answers help file.

open GP, '|c:/gnuplot/bin/pgnuplot.exe';
use FileHandle;
GP->autoflush(1);
print GP 'plot sin(x)', "\n";
sleep 3;
close GP;
exit;

To keep the Gnuplot screen active after Perl closes the first code line 
should be:

open GP, '|c:/gnuplot/bin/pgnuplot.exe -persist';

For people such as myself who are not Gnuplot experts or professional 
computer programmers, discovering exactly which commands like that need to

be used can mean the difference between success and failure of a project.

Another question relates to how to get Gnuplot to send information back to
a 
Perl program.
