png method error while using GD::Graph in Perl

Question

While compiling a perl script for making a graph and saving it into png file, I get the following error - Can't locate object method "png" via package "GD::Graph::bars" (perhaps you forgot to load "GD::Graph::bars"?)

Any idea how to solve it ?

The following is my code -

use CGI ':standard';
use GD::Graph::bars;
unlink("abc.png");
open (PIC, ">abc.png") or die "an error occurred: $!";
binmode PIC;

my @data = (["Jan", "Feb"],[23, 5]);

my $mygraph = GD::Graph::bars->new(500, 500);

$mygraph->set(
x_label     => 'Month',
y_label     => 'Number of Hits',
title       => 'Number of Hits in Each Month in 2002',) or warn $mygraph->error;

my $myimage = $mygraph->plot(\@data) or die $mygraph->error;

print PIC $mygraph->png;
close(PIC);

Thanks

Got the error - print PIC $mygraph->png; I need to use print PIC $myimage->png;
