/* Graph
* Versin 0.1
* Date 29 janv 2015
* Auteur Sangfeust
*
* Classe de gestion pour l'affichage d'un graphique avec des axes multiples!!
* Il semble qu'il faille faire très attention à la gestion des CANVAS et à la superposition des
* contrôles sur le PLOT car cela peut tout faire foirer !!
*
* Info:
* Cette version est adapté pour l'affichage d'un log AKEH !
* Il faut partir de cette base pour d'autre graphique!!
*
* How to:
* TBD
