Declaration
Global handler:
 ENTRY   OnNewDiaTrendTimeInt(IN INT _refId, IN TIME _bt, IN TIME _et, IN INT _case, IN INT _subCase)
 ; script actions
 END  OnNewDiaTrendTimeInt

Special handler:
 ENTRY XXX_OnNewDiaTrendTimeInt(IN TIME _bt, IN TIME _et, IN INT _case, IN INT _subCase)
 ;  script actions
 END XXX_OnNewDiaTrendTimeInt

Parameters
_refId Parameter of INT type (required for global handler).
XXX Name of Reference variable connected to graphic object (without the character "_").
_bt, _ec Displayed time interval (begin time and end time).

Description
The picture event is being generated by displayer of Graph type, whenever the time interval displayed in the displayer is being changed. The parameters _bt and _et represents new time interval. The parameter _case, according to the following table, determines the type of the event, when the time interval changed and the parameter _subCase specifies the use of the parameter _case:
 
value of parameter _case Event type
0 First opening of the graph - immediately after opening the graph, or after calling the function %HI_SetConnectedObj.
1 When the user defines a time interval on time axis. If:
2 Use of a zoom. If:
  • _subCase = 0 - destroy zoom
  • _subCase = 1 - use zoom
3 Time interval change caused by a data shift in live graph. If:
  • _subCase = 0 - shift caused by new values
  • _subCase = 1 - shift caused by deactivation of the button in graph window

!!! Calling the function %HI_SetDiagTimes doesn't activate the picture event OnNewDiaTrendTimeInt !!!


Example
The picture event handler for the displayer called Graph with the reference variable _graph.

 
ENTRY graf_OnNewDiagTrendTimeInt(IN TIME _bt, IN TIME _et, IN INT _case, IN INT _subCase)
   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
       ELSIF _subCase = 0 THEN    ; use of zoom
      ENDIF
