Hi Monks,

I want to have a hbar or bar chart for my top 20 mail users with GD::Graph::hbars or GD::Graph::bars

My ultimate goal is to have a STACK bar chart since I have top 20 senders and recipients.

I have 2 files /tmp/senders.txt and /tmp/recipients.txt.

Let's first discuss one file. this time /tmp/senders.txt

DATA of /tmp/senders.txt

__DATA__
sender@domain1.com
sender@domain2.com
noreply@domain1.com
noreply@domain1.com
sender@domain1.com
noreply@domain1.com
[download]

According to the above file ( Remember, This is just a sample file. Real file may contain about 1000 lines )

sender@domain1.com has 2 mails

sender@domain2.com has 1 mail

noreply@domain1.com has 3 mails

It reads it from start to end. when there are duplicates, It counts one by one.

This is the code for it

my $logfile = '/tmp/senders.txt';
open my $fh, '<', $logfile or die "Could not open $logfile : $!";

my %count=();
while (my $line = <$fh>) {
  foreach my $word (split /\s+/, $line) {
     ++$count{$word};
     #print "$word\n";
     #print "$count{$word}\n";
     #print "<br />";
     #print " \n";
  }
}

for my $word ( (sort { $count{$b} <=> $count{$a} }  keys %count) [0..1
+9] ) {
    #print "$word $count{$word}\n";  # THIS shows top 20 emails addres
+s and its count. 
}

close $fh;

Now What I need is to draw a hbar or bar chart with top 20 email addresses and their counts.

I have lost with below code? Could you pls correct me to go ahead.. ?

my @word = map{ $count{$_} || 0 } qw($word);
my @count_word = map{ $count{$_} || 0 } qw($count{$word});

my $data = GD::Graph::Data->new([
    [@word],
    [@count_word],
]) or die GD::Graph::Data->error;
[download]

Here's the full code

#!/usr/bin/perl
use CGI ':standard';
use strict;
use warnings;
use GD::Graph;
use GD::Graph::hbars;

my $logfile = '/tmp/senders.txt';
open my $fh, '<', $logfile or die "Could not open $logfile : $!";

my %count=();
while (my $line = <$fh>) {
  foreach my $word (split /\s+/, $line) {
     ++$count{$word};
     #print "$word\n";
     #print "$count{$word}\n";
     #print "<br />";
     #print " \n";
  }
}

for my $word ( (sort { $count{$b} <=> $count{$a} }  keys %count) [0..1
+9] ) {
    #print "$word $count{$word}\n";
}

close $fh;  

my @word = map{ $count{$_} || 0 } qw($word);  #I think This is where I
+ have gone wring
my @count_word = map{ $count{$_} || 0 } qw($count{$word}); # I think T
+his is where I have gone wring 

my $data = GD::Graph::Data->new([
    [@word],
    [@count_word],
]) or die GD::Graph::Data->error; 


my $graph = new GD::Graph::hbars(750,450);
$graph->set(
    x_label => 'Email Users',
    x_label_position => 1/2,
    x_labels_vertical => 1,
    y_label => 'Count',
    title => 'Top Email Users',
    values_vertical => 0,
    show_values => 1,
    box_axis => 0
);

my $font = '/usr/share/fonts/gnu-freefont_freesans/FreeSans.ttf';
#my $font = '/usr/share/fonts/dejavu/DejaVuSans.ttf';
$graph->set_title_font($font,14);
$graph->set_values_font($font, 8);
$graph->set_x_axis_font($font,8);
$graph->set_y_axis_font($font,8);
$graph->set_legend_font($font,8);
$graph->set_x_label_font($font,12);
$graph->set_y_label_font($font,12);

print header('image/png');
$graph->plot($data) or die $graph->error;
binmode STDOUT;
print $graph->gd->png;
