New and Need Help

[eluser]Unknown[/eluser]
I am new to codeigniter (CI) and I have found it ot be a nice framework so far.
It does aid me in writing application but I have now ran into a major obsticle.
I have classes and libraries which I have been using in my PHP and have had no luck in integrating them with CI.
One example is a php graph library known as phpGraphLIB.

With normal php wil would do the following

Code:

include('phpgraphlib.php');
$graph = new PHPGraphLib(500,350);
$data = array(12124, 5535, 43373, 22223, 90432, 23332, 15544, 24523, 32778, 38878, 28787, 33243, 34832, 32302);
$graph->addData($data);
$graph->setTitle('Widgets Produced');
$graph->setGradient('red', 'maroon');
$graph->createGraph();

When I try within CI, all I get is a message saying

The image “http://localhost/calllog/” cannot be displayed, because it contains errors.

How would be able to reuse this classes and libraries back in the CodeIgniter.

Thanks in advance.

Checkout this page of the user guide, http://ellislab.com/codeigniter/user-gui...aries.html
It details how to create a CI library, so you'll need to edit phpgraphlib.php so it conforms to CI library standards and then you'll be able to use it.
