- Copy the open-flash-chart.swf file to assets/swf/
- Copy the js/swfobject.js to assets/js/
- Edit file graph.php, find this following lines :
$this->js_path = 'js/';
$this->swf_path = '';
Edit to :
$this->js_path = base_url().'assets/js/';
$this->swf_path = base_url().'assets/swf/';

Contoller :
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
Class Statistic extends Controller {
function Statistic(){
parent::Controller();
//$this->freakauth_light->check('user');
//load the models
$this->load->model('vouchermodel');

//PIE chart, 60% alpha
//
$this->graph->pie(80,'#505050','{font-size: 12px; color: #404040;');

// pass in two arrays, one of data, the other data labels
//
$this->graph->pie_values( $bp_qty, $bp_label );
//
// Colours for each slice, in this case some of the colours
// will be re-used (3 colurs for 5 slices means the last two
// slices will have colours colour[0] and colour[1]):
//
$this->graph->pie_slice_colours( array('#d9db35','#487daf','#d00000','#4ae331') );
$this->graph->set_tool_tip( '#val# Vouchers' );
