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

dear perl monks, Been searching for articles & sample codes regarding GD::Graph::mixed module but I'm not able to find one showing 2-yaxis mixed graph (e.g. Y1 is bar & Y2 is lines). Is this available/supported? or any other module you can recommend that I can explore? thanks much!...

    #!perl
use strict;
use GD::Graph::mixed;

my @data = ( 
    ["1st","2nd","3rd","4th",],
    [ 10,11,12,13],
    [ 1,2,3,4],
  );

my $graph = GD::Graph::mixed->new(400, 300);
$graph->set( 
      types => ['bars','lines'],
      two_axes  => 1,
      x_label   => 'X Label',
      y1_label  => 'Y1 label',
      y2_label  => 'Y2 label',      
      title     => 'Some simple graph',
      y_max_value   => 20,
      y_tick_number => 5,
      y_label_skip  => 1 ,
  ) or die $graph->error;

my $gd = $graph->plot(\@data) or die $graph->error;

open IMG, '>','mixed.gif' or die $!;
binmode IMG;
print IMG $gd->gif;
