setting up phpChart in laravel - php

Question

Environment:Amazon EC2. Ubuntu x64. (GD library installed)
I'm recently using phpChart for graph and report in laravel framework.
I'm stuck at the beginning stage.
Here's what I've done.
1.Unzip the contents in phpChart_Lite to /var/www/app/libraries/phpChart.
2.Edit composer.json and add :
"autoload": {
"classmap": [
...
"app/libraries"
]
},
3.run:composer dump-autoload
4.modify conf.php in phpChart_Lite
define('SCRIPTPATH',app_path().'/libraries/phpChart_Lite/');
Here's my test page code:
<?php
require_once(app_path()."/libraries/phpChart_Lite/conf.php");
$pc = new C_PhpChartX(array(array(11, 9, 5, 12, 14)),'basic_chart');
$pc->draw();
?>
ps.my app_path() is verified by "echo app_path()" and it is "/var/www/app".
Here's my error message:
Unknown: Failed opening required '/var/www/public//var/www/app/libraries/phpChart_Lite//conf.php'
(include_path='/var/www/vendor/phpseclib/phpseclib/phpseclib:.:/usr/share/php:/usr/share/pear')

After a lot of try-and-error, I somehow found the root cause, I guess.
There are actually two main issue there. And here's my solution.
1.For my issue explained in the very first post.
In the conf.php file in phpChart_Lite folder. The SCRIPTPATH is somehow prefixed with /var/www/public.
However, in my apache2.conf file states the directory to be /var/www. Regardless this prefix, I use a absolute path for SCRIPTPATH. The following modification works for me:
define('SCRIPTPATH','../app/libraries/phpChart_Lite/');
The error was gone. But the second issue appears, that is the chart doesn't show up.
Open the Chrome Developer Tool(press F12). On the 'Console' tab, I found error 404 for loading phpChar_Lite/js. One of the error messages as following:
http://myip/app/libraries/phpChart_Lite/js/highlighter/styles/zenburn.css
As the design of Laravel, only public folder can be access by external request.
So I got second issue. And here's my solution.(not a secured method)
2.Move the phpChart_Lite to public folder. Modify the code of test page:
include_once(public_path()."/phpChart_Lite/conf.php");
Modify the conf.php in public/phpChart_Lite:
define('SCRIPTPATH','phpChart_Lite/');
Everything's just fine now.
If you consider phpChart is too complicate to configure with, you might want to try pChart2.0.
It doesn't require much setting. But the graph is terribly ugly.
I prefer phpChart for it's graph and function calls, though the setting is a little complicated and not laravel friendly.
