    Hi JrKoh ,

     

    You can create a calculated column like

     

     

    Time = TIME(HOUR([DateTime]),MINUTE([DateTime]),0)

    Hi Stephen,

    With your solution in mind, I found a way to downsample the data. I created 2 calculated column, Time_1min and Time_H and wrote another DAX measure and put it into the chart filter. I then key in the number into the filter to determine which sampling:

     

    Downsample =
    SWITCH(
    TRUE(),
    SUM(Sensor[Time]) == SUM(Sensor[Time_H]),1,
    SUM(Sensor[Time]) == SUM(Sensor[Time_1min]),3
    )

     

    per hour
     

    per min
