ImageGraph - General
From vtiger.com

Includes
The following 3 lines are required at the beginning of the script
require_once('include/utils/GraphUtils.php');
include_once('Image/Graph.php');
include_once('Image/Canvas.php');
Image Graph Factory
Image Graph implement an object factory which allow manipulation of all elements of a graph by setting properties or calling methods.
Syntax is :
$obj =& Image_Graph::Factory(class_name[,param_array]);
where :
class_name is the name of the element class, ex: 'Image_Graph_Legend' or a short name like 'plotarea'. param_array is an array of parameters for the class constructor.
Embedding classes instantiation
ImageGraph factory allows embedded calls. Examples can be found using the following syntax :
$graph->add(
Image_Graph::vertical(
$title =& Image_Graph::factory('title', array('My Title',10)),
Image_Graph::vertical(
Image_Graph::horizontal(
$plotarea =& Image_Graph::factory('plotarea'),
$legend_box =& Image_Graph::factory('legend'),
80
),
$footer =& Image_Graph::factory('title', array('A Footer',8)),
90
),
5
)
);
This syntax works nice in a standalone PHP script. It does not in a Vtiger module. The correct calls are :
$title =& Image_Graph::factory('title', array('My Title',10));
$plotarea =& Image_Graph::factory('plotarea');
$legend_box =& Image_Graph::factory('legend');
$footer =& Image_Graph::factory('title', array('A Footer',8));
$graph->add(
Image_Graph::vertical(
$title,
Image_Graph::vertical(
Image_Graph::horizontal($plotarea,$legend_box,80),
$footer,
90
),
5
)
);
