 * type is thicker (10 pixels?) representing on which CPU a process is running
 * (and this only in running state).

 * x_min : time of the last event context for this process kept in memory.
 * x_max : time of the current event.
 * y : middle of the process in the process list. The process is found in the

 *
 * The choice of lines'color is defined by the context of the last event for this
