/**
	A surface can be horizontal (default) or vertical: this defines how 
	the filling of the surface is done. For a horizontal surface, the 
	filling is done between the points and the associated horizontal axis 
	and for a vertical surface, the filling is done between the points 
	and the associated vertical axis. 
	The series can be associated with a secondary axis. For example, if 
	the surface series is horizontal and is associated with the top axis 
	(secondary axis), the filling is done between the top axis and the points.

I am a 29 years old guy and I live with my girlfriend in Hoegaarden, little city from Belgium well known for its white beer Smile | :) .
I studied as an industrial engineer in electronics but I oriented myself more towards software development when I started to work.
Currently I am working in a research centre in mechatronica. I mainly develop in C++ but I also do a bit of Java.
When I have so spare time, I like to read (mainly fantasy) and play electric guitar.
