Charts Library

Small modification, your constructor should set the application dir automatically using APPPATH like so:

Code:

class Charts {

    var $obj;
    private $_ext_path;
    private $_img_path = "charts";

    function Charts()
    {
        $this->obj =& get_instance();
        $this->obj->load->helper('string');

                $this->_ext_path = APPPATH;

        include($this->_ext_path."/classes/pData.class");  
        include($this->_ext_path."/classes/pChart.class");
    }

// ......................

No point duplicating the config setting.
