Number of occurrences per hour

[Anonymous]

Hello to all,

I have this data table:

And I would like to be able to display in the "fréquence_incrémentation" column via a measurement, the number of values per row of "DT 10min" that I have for each existing "DT 1h".
Example for my screenshot above: I count for DT 1h = 16:00:00 --> Number of different DT 10 min = 4 since I have 16:40:00; 16:30:00; 16:10:00 and 16:00:00.

Thanks in advance,

Joël

Sorry, I add a detail to my request, I would like this calculation to be done according to "DT 1h" but also according to the value of the column "id_mesure_faucon".

Thanks in advance,

Joël
