Operations by hour
Hi everyone ! I'm having some problems trying to calculate how many cars are in different hours. There is a problem of a parking lot.
I have the next data:
| CheckIn | Checkout |
| 25/08/2021 07:00 | 25/08/2021 07:34 |
| 25/08/2021 07:47 | 25/08/2021 08:48 |
| 25/08/2021 08:47 | 25/08/2021 08:59 |
| 25/08/2021 08:47 | 25/08/2021 08:59 |
| 25/08/2021 08:50 | 25/08/2021 09:32 |
| 25/08/2021 08:53 | 25/08/2021 11:32 |
| 25/08/2021 09:01 | 25/08/2021 11:32 |
As you can see there is the CheckIn and the CheckOut. But I DONT WANT THE NEXT:
With CheckIn
| Hour | Operations |
| 7 | 2 |
| 8 | 4 |
| 9 | 1 |
With CheckOut
| Hour | Operations |
| 7 | 1 |
| 8 | 3 |
| 9 | 1 |
| 11 | 2 |
WHAT I WANT IS TO CALCULATE HOW MANY CARS ARE IN THE PARKING LOT. EACH ROW IS A CAR, WHAT I WANT IS THE NEXT:
| Hour | Cars |
| 7 | 2 |
| 8 | 5 |
| 9 | 2 |
| 10 | 2 |
| 11 | 2 |
At 7 am there was 1 car, at 8 am there were 5 cars: 1 from 7 am (the CheckOut is at 😎 and 4 with the CheckIn at 8.
Please, help
Thank you guys
Anonymous you need to create a table for hours to achieve the goal, you can add this table using following DAX:
Hours = SELECTCOLUMNS ( GENERATESERIES ( 0, 23, 1 ), "Hour", [Value] )Add a new measure to count cars by the hour:
Count Cars = VAR __hour = MAX ( Hours[Hour] ) RETURN CALCULATE ( COUNTROWS ( Parking ), __hour >= HOUR ( Parking[CheckIn] ), __hour <= HOUR ( Parking[Checkout] ) )To visualize, use a table visual, add Hour columns from Hour table and Count Rows measure and you will get the following result:
