Your program shouldn't even compile. I get:
"Type of arg 1 to push must be array (not array element) at ..."
The first argument of push should be an array, not a scalar (even if that
scalar is a reference to an array).
push( @{$graph_data->[0]}, $x_axis );
(the parentheses around $x_axis are unnecessary.)
If you are having more trouble, use the Data::Dumper module to inspect the
contents of your AoA:
use Data::Dumper;
print Dumper(\$graph_data);
