odometer jpgraph is not working in php - php

Question

I want to show odometer simple example but its not working. My jpgraph files are within src/ directory. Myline graph is working but for odometer which file to use ??
PHP code:
<?php
require_once ('/src/jpgraph.php');
require_once ('/src/jpgraph_line.php');
require_once ('jpgraph/jpgraph_odo.php');
// Create a new odometer graph
$graph = new OdoGraph(500,180);
$odo = array();
// Now we need to create an odometer to add to the graph.
for( $i=0; $i < 5; ++$i ) {
$odo[$i] = new Odometer();
$odo[$i]->SetColor('lightgray:1.9');
$odo[$i]->needle->Set(10+$i*17);
$odo[$i]->needle->SetShadow();
if( $i < 2 )
$fsize = 10;
else
$fsize = 8;
$odo[$i]->scale->label->SetFont(FF_ARIAL,FS_NORMAL,$fsize);
$odo[$i]->AddIndication(92,100,'red');
$odo[$i]->AddIndication(80,92,'orange');
$odo[$i]->AddIndication(60,80,'yellow');
}
// Create the layout
$row1 = new LayoutHor( array($odo[0],$odo[1]) );
$row2 = new LayoutHor( array($odo[2],$odo[3],$odo[4]) );
$col1 = new LayoutVert( array($row1,$row2) );
// Add the odometer to the graph
$graph->Add($col1);
// ... and finally stroke and stream the image back to the browser
$graph->Stroke();
?>
Error:
Fatal error: Class 'OdoGraph' not found in C:\wamp\www\PowerMonitor\odometer.php on line 9

I had similar problem of this Fatal error. As Gal pointed out, it is problem with in-proper JPGRAPH_ODO.PHP loading or missing. You can download the file from here and keep it under src directory with other files. Then apply
require_once ('/src/jpgraph_odo.php');
might work.
