Hi Perl Monks
I want to have a doughnut chart for Hard Disk. It should display Used space, Free Space and Total etc.. Now, I wrote a code for it. It's a pie chart.. How can I get a doughnut for it. I want to display with CGI.
Here's my code
#!/usr/bin/perl
use CGI ':standard';
use strict;
use warnings;
use GD::Graph::pie;
my $cmd_1 = "sudo df -h |grep /var |awk '{print \$2}' | sed -e 's/.\$/
+/'";
my $cmd_2 = "sudo df -h |grep /var |awk '{print \$3}' | sed -e 's/.\$/
+/'";
my $result_used = qx/ $cmd_1 /; #$result_used shows 1.4
my $result_free = qx/ $cmd_2 /; #$result_free shows 85
# Both the arrays should same number of entries.
my @data = (['Used', 'Free'],
[$result_used, $result_free]);
my $mygraph = GD::Graph::pie->new(300, 300);
$mygraph->set(
title => '/var Partition, Size in GB',
'3d' => 0,
#'3d' => 1,
) or warn $mygraph->error;
$mygraph->set_value_font(GD::gdMediumBoldFont);
my $myimage = $mygraph->plot(\@data) or die $mygraph->error;
print "Content-type: image/png\n\n";
print $myimage->png;
I think Doughnut chart is NICER. But, I can't find many docs for them.
Can U guys help me? Better methods are also welcome...

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
