1GnuplotIF version 1.8 2===================== 3 4GnuplotIF is a simple and easy to use Perl interface to gnuplot. gnuplot is a 5freely available, command-driven graphical display tool for Unix. It compiles 6and works quite well on a number of Unix flavours as well as other operating 7systems. The following module enables sending display requests to gnuplot 8through simple Perl subroutine calls. 9 10GnuplotIF starts gnuplot as a separate process. The plot commands are send 11through a pipe. The graphical output from gnuplot will be displayed 12immediately. 13 14Several independent plots can be started from one script. Each plot has its 15own pipe. All pipes will be closed automatically when the script terminates. 16The gnuplot processes terminate when the corresponding pipes are closed. Their 17graphical output will now disappear. 18 19GnuplotIF is similar to gnuplot_i , a C interface to gnuplot 20( http://ndevilla.free.fr/gnuplot/ ), and to gnuplot_i++ , a C++ interface 21to gnuplot ( http://jijo.cjb.net/code/cc++ ). 22 23 24INSTALLATION 25 26To install this module type the following: 27 28 perl Makefile.PL 29 make 30 make test 31 make install 32 33DEPENDENCIES 34 35This module requires these other modules and libraries: 36 37 gnuplot ( http://sourceforge.net/projects/gnuplot ) must be installed. 38 39 The module IO::Handle is used to handle output pipes. 40 Your operating system must support pipes, of course. 41 42 The environment variable DISPLAY is checked for the display. 43 44COPYRIGHT AND LICENCE 45 46 Copyright (C) 2005-2016 by Fritz Mehner 47 48 This module is free software; you can redistribute it and/or modify it under 49 the same terms as Perl itself.
