WampServer

I am trying to run a simple code to generate a line graph in php using jpgraph on wamp5, but i am getting following error msg.

Warning: include(../jpgraph.php) [function.include]: failed to open stream: No such file or directory in C:\wamp\www\jpexamp.php on line 2

Warning: include() [function.include]: Failed opening '../jpgraph.php' for inclusion (include_path='.;C:\wamp\www\src') in C:\wamp\www\jpexamp.php on line 2

Warning: include(../jpgraph_line.php) [function.include]: failed to open stream: No such file or directory in C:\wamp\www\jpexamp.php on line 3

Warning: include() [function.include]: Failed opening '../jpgraph_line.php' for inclusion (include_path='.;C:\wamp\www\src') in C:\wamp\www\jpexamp.php on line 3

Fatal error: Class 'Graph' not found in C:\wamp\www\jpexamp.php on line 11

i have changed the windows include_path='.;C:\wamp\www\src' because that is where all my jpgraph files are present. i am not able to understand why i am getting this error. pls help me.

Thanx
