// /* The idea of this widget is to display and edit the profile.
//  * It has:
//  * 1 - ToolTip / Legend item, displays every information of the current mouse position on it, plus the legends of the maps.
//  * 2 - ToolBox, displays the QActions that are used to do special stuff on the profile ( like activating the plugins. )
//  * 3 - Cartesian Axis for depth ( y )
//  * 4 - Cartesian Axis for Gases ( y )
//  * 5 - Cartesian Axis for Time  ( x )
//  *
//  * It needs to be dynamic, things should *flow* on it, not just appear / disappear.
