How to create a "proper" array?

bfdi533 has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to use Text::Graph and it says it is called as follows:

my $graph = Text::Graph->new( 'Bar' );
print $graph->to_string( [1,2,4,5,10,3,5],
                         labels => [ qw/aaaa bb ccc dddddd ee f ghi/ ]
+,
                       );

I am looking through a database result set and generating what I thought was an "array" as follows:

while (@rowdata = $sth->fetchrow_array()) {
    push (@chart_data, $rowdata[2]+0);
    push (@chart_labels, $rowdata[0].' '.$rowdata[1].':00');
}
$graph->to_string(@chart_data, labels=>@chart_labels);
[download]

The issue is that my "array" craps out when I call

$graph->to_string

as I do not think it is the "same kind of array" that it is expecting.

How do I create the kind of "array" the example call is expecting?
