The problem is, you shouldn't be printing $q->header() to set the header.
(Never, never, ever print() to STDOUT in a CGI Application module!)
Instead, you need to use the header_props() method:
sub showdetails{
my $self = shift;
my $q = $self->query();
# WRONG: print $q->header( {-type=>'image/png'} );
# Instead, call this CGI-App method:
$self->header_props({-type=>'image/png'});
# showgraph() MUST NOT print()! It should return data, instead.
my $graph_binary_data = showgraph();
# WRONG: print $q->end_html();
# Instead, return output:
return $graph_binary_data;
}
This ought to do it.
TTYL,
