Count if values

[Anonymous]

Hello to all,

I ask for your help concerning a measurement of type "IF".

I would like to display "1000" when the value of the measurement "Digester level (m)" reaches the value of 6 then continue to display "1000" as long as the value of the measurement has not reached a value lower than 4. When the value is below 4, stop counting until the cycle repeats itself. Today here is my measurement:

Période torchée =

VAR _selDate = SELECTEDVALUE(dim_date[DT (1min)])

VAR _maxDate = CALCULATE(LASTNONBLANK(dim_date[DT (1min)], [booléen niveau digesteur]), FILTER(ALLSELECTED(dim_date[DT (1min)]), dim_date[DT (1min)] < _selDate))

VAR _maxDate_dig = CALCULATE(LASTNONBLANK(dim_date[DT (1min)], [Niveau Digesteur(m)]), FILTER(ALLSELECTED(fact_point_torch_juin), [Niveau Digesteur(m)] >= 4))

RETURN

IF(AND(CALCULATE([booléen niveau digesteur]=1000,FILTER(ALLSELECTED(dim_date),dim_date[DT (1min)] = _maxDate)),[Niveau Digesteur(m)]>=4),1000,0)

I obtain this result, the problem is that the "IF" does not wait that the measurement reaches again the value 6 to post 1000.

The cycle does not work, it would be necessary that the zone framed in red is equal to zero here.

Is my problem clear ?

Thank you in advance,

Have a nice day

Joël

@Anonymous The problem is clear, and it is a nice one.  Powert BI is really bad at hysteresis  (it has no memory) but I think with a bit of DAX trickery this can be achieved, with LASTNONBLANKVALUE or similar.
