Count for every day from startdate and enddate

[bdeleur]

Hi,

I have a data set witch contains every movement a patient does in the hospital.

Every movement has it's own row.

The row has an start and end date so you can determine where the patient was for every day. But how 🙂

Reference	start date	end date	department
12345	1-1-2022 10:00	1-1-2022 15:00	a
12345	1-1-2022 15:00	1-1-2022 16:00	b
9842	31-1-2022 09:35	12-2-2022 15:34	a
6587	2-1-2022 3:25	3-1-2022 16:35	a

I want a calculation for every day (and for every hour) how many patients where present

Expected outcome for department a:

Date	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23
1-1-2022	1	1	1	1	1	1	1	1	1	1	2	2	2	2	2	1	1	1	1	1	1	1	1	1
2-1-2022	1	1	1	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2

The problem is that 1 reference can be present several times so the count will not be correct when I count the rows.

I hope somebody can help me.

Hi @bdeleur 
Please refer to attached sample file with the solution

Count = 
VAR CurrentDate = SELECTEDVALUE ( 'Date'[Date] )
VAR CurrentHour = SELECTEDVALUE ( Hours[Hour] )
RETURN
    SUMX ( 
        VALUES ( 'Table'[department] ),
        VAR CurrentDepartmentTable = CALCULATETABLE ( 'Table' )
        VAR FilteredTable = 
            FILTER ( 
                CurrentDepartmentTable, 
                VAR StartDate = 'Table'[start date]
                VAR EndDate = 'Table'[end date]
                RETURN
                    CurrentHour 
                        IN SELECTCOLUMNS ( 
                            GENERATESERIES ( MAX ( CurrentDate, StartDate ), MIN ( CurrentDate + 0.99, EndDate ), 1/24 ), 
                            "@Hour", HOUR ( [Value] ) 
                        )
            )
        RETURN 
            COUNTROWS ( FilteredTable )
    )

Max Count = 
MAXX ( 
    CROSSJOIN ( 
        VALUES ( 'Date'[Date] ), 
        VALUES ( Hours[Hour] ) 
    ),
    [Count]
)

Min Count = 
MINX ( 
    CROSSJOIN ( 
        VALUES ( 'Date'[Date] ), 
        VALUES ( Hours[Hour] ) 
    ),
    [Count]
)

Average Count = 
AVERAGEX ( 
    CROSSJOIN ( 
        VALUES ( 'Date'[Date] ), 
        VALUES ( Hours[Hour] ) 
    ),
    [Count]
)

Hi @tamerj1 

Works perfect. Thank you!

I also want a min, max and average for the whole day. Is that also possible with your code?

Don't know what you mean. But the result is like this in Excel:

The data looks like this and contains a column Ward:

The formula I use in excel is: 

AANTAL.ALS($B:$B;"<"&($K7+AL$6))-AANTAL.ALS($C:$C;"<"&($K7+AL$6))

Column B is the start date en C is the End date

Aantal.als = count.if in English.

In excel I use this formula:

Can you please provide more data regarding the output. Didn't understand the required output properly.
Thank you.

Hi @Anonymous,

Tnx for looking at my problem. I want for every day and every hour a count how many patients there are in a ward. This is an example for ward A for 2 days but it continues for the whole year and with a slicer for other wards also.

Makes it more clear now?
