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 the INT type (required for global handler).
XXX	Name of the Reference variable connected to graphic object (without the character "_").
_bt, _ec	Displayed time interval (begin time and end time).
_case	Input parameter of the INT type (see the table below).
_subCase	Input parameter of the INT type - specifies the use of the parameter _case (see the table below).

Description

The picture event is being generated by displayer of the 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 %HI_SetConnectedObj function.
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 %HI_SetDiagTimes function 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
