Hey v-yulgu-msft

 

sorry, that is a mistake on the chart. I edited my post and it messed up it. So the grouping is:

  • 10:00
    • 10:11, 10:14, 10:18

 

Best,

Ike

Hi Ikeumlaut,

 

I am still confused about this calculation. That case, the Cumulative value for "28.3.18 10:10" in result table should be 2 rather than 1. Also, the Cumulative value for "28.3.18 10:20" in result table should be 0.

    Hey,

     

    I do not want the sum of the values. Instead the cumulative distinct count of devices that have sent a value of 1. So I want to know how many devices have a value of 1 at each time interval. Sometimes the device sents the value at the interval, but sometimes it has sent the message right before the interval so I need to take that into account somehow.

     

    Thank you for helping out!

     

    Best,

    Ike
