If I'm not mistaken (I didn't run any code), you are pushing lists with one element (namely the bigest index of the list you IMO intend to push) onto @fixed.

After that you push a lot of arrays containing only 1 (that is: (1,)) onto @graphdata.

please use strict!

try something like this, take the time to notice the differences between your example and this one: 

use strict;

my @labels = qw(my one word labels);

my @graphdata = (\@labels);

my @sets = ();

# looping and data building, fillings @sets

foreach my $set (@sets) {
     my $se = [];
     # process $set into $se
     push @graphdata, $se;
}

my $graph; 
# GD::Graph stuff
my $gd = $graph->plot(\@graphdata);

Try to understand what you are doing, read a lot, debug your code (e.g. use Data::Dumper), read perldata and perlref thoroughly ;-)
