Graphics / Pie Charts
In order to provided stat data on my companies website my boss has asked me
to write a program that pulls stat data from our database and display it on
a page in graphs and pie charts. He'd like the program to hand the abilty to
up the minute request, so I have to generate them on the fly.
The database side I can do eaily. However I haven't ever played with graphs
and charts.
Someone recommend that I use GDGraph-1.43. Looking at it there hasn't been
an update since 2003. So before I go play with it I figure I ask here if
anyone has done and graph stuff, and if there a better module to use under
mod perl.
Thanks,
David

I don't know if it's too much for a posting but, i 've just build a module
under mod_perl to do just that, i call whenever i need a pie chart. You call
it like this:
First you put a handler in httpd.conf:
--------------------------------------
<Files grafico>
SetHandler perl-script
PerlHandler UB::Grafico
</Files>
The calling url is:
-------------------
http://www.ubpf.cl:8080/grafico?labels=e,c,b;values=1,3,3;title=
the module is:
--------------
package UB::Grafico;
use Apache::Constants qw/OK/;
use CGI ':standard';
use GD::Graph::pie;
use strict;
sub handler {
my $r = shift;
$r->no_cache(1);
my @labels = split /,/, param("labels");
my @values = split /,/, param("values");
# Both the arrays should same number of entries.
my @data = (\@labels, \@values);
my $mygraph = GD::Graph::pie->new(80, 80);
$mygraph->set(
title => param("title"),
'3d' => 1,
) or warn $mygraph->error;
$mygraph->set_title_font(GD::gdTinyFont);
$mygraph->set_value_font(GD::gdTinyFont);
$mygraph->set(dclrs => [ qw(yellow red cyan) ] );
my $myimage = $mygraph->plot(\@data) or die $mygraph->error;
$r->send_http_header("image/png");
print $myimage->png;
return OK;
}
1;
Good Luck
Hans

I asked a similar question on PerlMonks recently:
http://perlmonks.org/?node_id=452166
I ended up settling on GD::Graph3D but I'll be interested to see if
someone here has a better idea.

Hi,

Both GTK+ and Perl::TK work really well. Using Perl GTK+ can actually
manipulate graphics through the Gimp.

You can try ImageMagick. Very nicely done.

If, by chance, you also have use for a general purpose templating
system, I've had great luck with Template-Toolkit
(www.template-toolkit.org.) Among [many] other things, it embeds GD
so you can write little templates that slurp in the data and produce
graphics with graphs, charts, etc. The learning curve is heavier than
just getting a quick-and-dirty graphing module to work (ala something
you'd do in CGI), but worthwhile if you're looking to add other
functions over time.
cheers
