in reply to Plot a spiral with gnuplot
When I use gnuplot I use its special file handle '-' and inline the data.
Would it be better to use a tempfile? and if so what are the advantages?
I'd write your code like this :-
use v5.12; use warnings; use autodie; use IO::Handle; open my $out,'|-','gnuplot'; say $out 'unset key'; say $out "plot '-' with lines lw 3"; for my $t (100..500) { say $out $t*sin($t*0.1),' ',$t*cos($t*0.1); } say $out 'e'; flush $out; <STDIN>; close $out;
