This code gives me a result: 

use strict;
use warnings;
use GD::Graph::bars;

my @data;
my $graph = GD::Graph::bars->new( 400, 300 );
for ( my $x=1; $x<10; $x++) {
        my @anotherarray=(1,2,3,4,5);
        push @data, [ @anotherarray ];
}

my $gd = $graph->plot(\@data) or die $graph->error;

open ( my $img, '>file.png') or die $!;
binmode $img;
print $img $gd->png;
close $img;

The result is five groupings of 8 (not 9, check your loop counter) lines each in a vertical bar chart in a PNG file.

I'm not sure which portions are different from your entire program, because you provided only a particular portion. That portion may not be the one at fault after all. Be sure to post small yet functional code snippets for the best results. Also, I made what changes were necessary to use the strict and warnings pragmas. That's always a good idea.

Now that you've seen a working example using your own data structure, you should be able to start comparing things to figure out what else could be wrong.
