OnNewDiaTrendTimeInt picture event

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).
_case	Input parameter of INT type (see the table below).
_subCase	Input parameter of INT type - specifies the use of the parameter _case (see the table below).

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: _subCase = 0 - return to the initial time interval (just as the button in the graph) _subCase = 1 - definition of a new time interval (just as the button in the graph)
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
   ENDIF
 END graf_OnNewDiagTrendTimeInt
