GnuplotIF version 1.8 ===================== GnuplotIF is a simple and easy to use Perl interface to gnuplot. gnuplot is a freely available, command-driven graphical display tool for Unix. It compiles and works quite well on a number of Unix flavours as well as other operating systems. The following module enables sending display requests to gnuplot through simple Perl subroutine calls. GnuplotIF starts gnuplot as a separate process. The plot commands are send through a pipe. The graphical output from gnuplot will be displayed immediately. Several independent plots can be started from one script. Each plot has its own pipe. All pipes will be closed automatically when the script terminates. The gnuplot processes terminate when the corresponding pipes are closed. Their graphical output will now disappear. GnuplotIF is similar to gnuplot_i , a C interface to gnuplot ( http://ndevilla.free.fr/gnuplot/ ), and to gnuplot_i++ , a C++ interface to gnuplot ( http://jijo.cjb.net/code/cc++ ). INSTALLATION To install this module type the following: perl Makefile.PL make make test make install DEPENDENCIES This module requires these other modules and libraries: gnuplot ( http://sourceforge.net/projects/gnuplot ) must be installed. The module IO::Handle is used to handle output pipes. Your operating system must support pipes, of course. The environment variable DISPLAY is checked for the display.
