setting up phpChart in laravel

问题

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.
