Help!

I am trying to use GD::Graph using data returned from a DBI call. But the layout of the data is not what the GRAPH module is expecting. DBI returns (r1c1, r1c2, r1c3) (r2c1, r2c2, r2c3), etc... and the graph module is expecting (r1c1, r2c2...)(r1c2, r2c2...)

Here is my code so far...

#! perl -w
use CGI ':standard'; 
use GD::Graph::bars; 
use DBI;

my $SQL = "SELECT A.YM, SUM(A.TC)FROM A GROUP BY A.YM ORDER BY A.YM
";

$dbh = DBI->connect('dbi:DB2:DB2W',"$mf_id" , "$mf_pw"); if ($DBI::err
+str) {print "$DBI::errstr";}
$sth = $dbh->prepare($SQL);                              if ($DBI::err
+str) {print "$DBI::errstr";}
$rc  = $sth->execute;                                    if ($DBI::err
+str) {print "$DBI::errstr";}
$data = $sth->fetchall_arrayref;

my $mygraph = GD::Graph::bars->new(800, 500);
$mygraph->set(      
    x_label     => 'Month',
    y_label     => 'Transactions',
    title       => 'Number of Transactions per Month',
    show_values => 1,
    bar_spacing => 10,
) or warn $mygraph->error;

my $myimage = $mygraph->plot(\@$data) or die $mygraph->error;
print "Content-type: image/png\n\n";
print $myimage->png;

Edit:larsen, changed title, added <code> tags and fixed formatting.
