Gnuplot script
[editar]Save this script to file "anim" then run the command line "gnuplot anim", you will get classe_D_*.gif (*=1, ..? ,17), if you have well installed gnuplot 4.0 or later.

Don't forget to set GDFONTPATH before running gnuplot with something like :
export GDFONTPATH=/var/lib/defoma/gs.d/dirs/fonts/
