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++ ).
