hi, it looks like PHP

It usess OO (Object oriented) programing.

so if you've never seen or done any OOD code before, then i suppose this will look unfamiliar.

I've done a bit of it before... But I've never came across something like this... (A mixture of PHP and the bold part codes) Mmm... Any idea how can I label my x-axis and y-axis???

It will be easy for others to read your code if you can use proper coding tags. Read the guidelines to use CODE tags.

It's most definitely in PHP.

I know this by:
[php]
<?php
[/php]

;)
