Integrating jpgraph in codeignator

#1
[eluser]Unknown[/eluser]
Hi All,

I am new to codeignator, As per my requirement i need to integrate jpgraphs in my codeignator project. I followed the below link for integrate jpgraph. But i am not able to understand below mentioned steps.

http://codeigniter.com/wiki/JP_Graph/

Installation
Setup

1) Download JpGraph (I used version 2.14 for PHP5) and copy the contents of the “src” folder to the “system/plugins/jpgraph” directory.

"I downloaded jpgraph. But here i did not found any system/plugins in jpgraph folder"

2) Create a directory “temp” in your document root (same directory as your index.php) to store the generated charts. Make sure this directory is writable by Apache.
3) If you use mod_rewrite, add the “temp” directory to your .htaccess exclusion list. My .htaccess file now looks like the following
" I did not understand step2 and step3"

So please give me a clear procedure for integrating jpgraph in codeignator.
As it a quick project. So please send the replay ASAP.

Thanks and Regards
Shankar.

Hello,
I am trying to use JpGraph with Codeigniter following the instruction given above, but it producing error. I need a way out. It would be great if someone could help.
Here is what I have done:

I have put all the contents of src folder into application/libraries/jpgraph/

My jpgraph library class location is
Code:
application/libraries/jpgraph.php

class Jpgraph {
    public function grouped_bars(){
        require_once ('jpgraph/jpgraph.php');
        require_once ('jpgraph/jpgraph_bar.php');

        $datay1=array(35,160,0,0,0,0);
        $datay2=array(35,190,190,190,190,190);
        $datay3=array(20,70,70,140,230,260);

        $graph = new Graph(450,200,'auto');    
        $graph->SetScale("textlin");
        $graph->SetShadow();
        $graph->img->SetMargin(40,30,40,40);
        $graph->xaxis->SetTickLabels($gDateLocale->GetShortMonth());

        $graph->xaxis->title->Set('Year 2002');
        $graph->xaxis->title->SetFont(FF_FONT1,FS_BOLD);

        $graph->title->Set('Group bar plot');
        $graph->title->SetFont(FF_FONT1,FS_BOLD);

        $bplot1 = new BarPlot($datay1);
        $bplot2 = new BarPlot($datay2);
        $bplot3 = new BarPlot($datay3);

        $bplot1->SetFillColor("orange");
        $bplot2->SetFillColor("brown");
        $bplot3->SetFillColor("darkgreen");

        $bplot1->SetShadow();
        $bplot2->SetShadow();
        $bplot3->SetShadow();

        $bplot1->SetShadow();
        $bplot2->SetShadow();
        $bplot3->SetShadow();

        $gbarplot = new GroupBarPlot(array($bplot1,$bplot2,$bplot3));
        $gbarplot->SetWidth(0.6);
        $graph->Add($gbarplot);
//        return $graph;
        return $graph->Stroke();
    }
}

My Controller:
Code:
class Six_Months_Trend extends MY_Controller
{
    function __construct() {
        parent::__construct();
    }
    
    public function index() {
        $this->load->library('jpgraph');
        $bar_graph = $this->jpgraph->grouped_bars();
        echo $bar_graph;
    }
}

The output in the view is:
