Well, you can plot graphs of your data in Perl, you just have to know what you are doing

Besides, who doesn't love a command line? Well, to do it in Perl is rather easy, and very customizable ... I'm sure ya'll can figure it out! Here's an example, sans formatting (e.g., float lookup_table[], etc.).
Code:
use warnings;
use strict;
use Math::Trig;
open (OUT, ">your_file.txt") or die "No go!";
for (0..90) {
print OUT sin($_); print OUT ", " unless $_ == 89;
}
Edit: and you can use the handy printf function, instead of print, for (as the f probably implies already) formatting. (e.g.,printf ("%.3f", sin (3.14159/4)); )
