SVG::Template::Graph 0.11

SVG::Template::Graph is a Perl extension for generating template-driven graphs with SVG.

SYNOPSIS

use SVG::Template::Graph;
$data = [
{
barGraph=>1,#
barSpace=>20,
title=> 1: Trace 1,
data => #hash ref containing x-val and y-val array refs
{
x_val =>
[50,100,150,200,250,
300,350,400,450,500,550],
y_val =>
[100,150,100,126,100,
175,100,150,120,125,100],

},
format =>
{ #note that these values could change for *each* trace
lineGraph => 1,
x_min => 0,
x_max => 600,
y_min => 50,
y_max => 200,
x_axis => 1, #draw x-axis
y_axis => 1, #draw y-axis

#define the labels that provide the data context.
labels =>
{
#for year labels, we have to center the axis markers
x_ticks =>
{
label =>[2002,2003,2004],
position=>[100,300,500],
},
y_ticks =>
{
#tick mark labels
label => [ -250, 0, 250, 500],
#tick mark location in the data space
position => [50, 100, 150, 200],
},
},
},
},
];


#construct a new SVG::Template::Graph object with a file handle
my $tt = SVG::Template::Graph->new($file);

#set up the titles for the graph
$tt->setGraphTitle([Hello svg graphing world,I am a subtitle]);

#generate the traces.
$tt->drawTraces($data,$anchor_rectangle_id);
#serialize and print
print $tt->burn();

Template::Graph:SVG is a module for the generation of template-driven graphs using Scalable Vector Graphics (SVG). Using this module, it is possible to define a template SVG document with containers which are populated with correctly scaled plot images.
