   IF _case = 0 THEN             ; open displayer of Graph type
   ELSIF _case=1 THEN             ; change of time interval
     IF  _subCase = 0 THEN       ; return to initial interval
     ELSIF  _subCase = 1 THEN   ; definition of a new time interval
     ENDIF
   ELSIF _case = 2 THEN          ; use of zoom
     IF _subCase = 0 THEN        ; destroying zoom
