How to Aggregate Temperature Column Per Hour Per Day

[Ibrahim_shaik]

Hi Power BI Community,

I have a date, time column in the time column i have 5 minute interval timestamp and a temp column which has temp value for every 5 minute timestamp.

I want to create a column in which i get the average temp value of the hour of the 5 minute intervals in an hour per day that is 24 values for a day.

Please give a solution.

I have used this DAX it gives me a blank column.

AverageTemperaturePerHour =

VAR CurrentDate = MAX('AmbTemp'[date])

VAR CurrentHour = HOUR(MAX('AmbTemp'[time]))

RETURN

    CALCULATE(

        AVERAGE('AmbTemp'[t_out]),

        FILTER(

            'AmbTemp',

            'AmbTemp'[date] = CurrentDate &&

            HOUR('AmbTemp'[time]) = CurrentHour

        )

    )

Please give a solution.

Hi, @Ibrahim_shaik 

May I ask if you have already solved this problem? On top of the DAX you wrote, just add an ALL.

Measure:

Expected = 

VAR CurrentDate = MAX('AmbTemp'[date])
VAR CurrentHour = HOUR(MAX('AmbTemp'[time]))
RETURN
    CALCULATE(
        AVERAGE('AmbTemp'[t_out]),
        FILTER(
            ALL('AmbTemp'),
            SELECTEDVALUE('AmbTemp'[date]) = CurrentDate &&
            HOUR('AmbTemp'[time]) = CurrentHour
        )
    )
