Help with measure to count where an event occured on a date

[Anonymous]

Hi experts,

I'm looking for some assistance in creating a measure that checks if one event or more occured on a particular date if it did then count as 1 ifelse 0.

I can easily count the total number of events that occur on a particular day but I'm stumped on how I create a measure to count only 1 where there may be many.

Amny help would be great.

Hi @Anonymous ,

You can create a measure as below to get it, please find the details in the attachment.

Measure = 
VAR _seldate =
    SELECTEDVALUE ( 'Date'[Date] )
VAR _count =
    CALCULATE (
        DISTINCTCOUNT ( 'Table'[Event] ),
        FILTER ( 'Table', 'Table'[Date] = _seldate )
    )
RETURN
    IF ( _count >= 1, 1, 0 )

Best Regards

Hi @Anonymous ,

Thank you for the reply, your calculation does exactly what I was hoping to do.
I do have one final question though, If I want to count the number days where there was an event how do I add that to the DAX?

What I need to be able to calculate is the number of dates where there was an event on, and the number dates where there wasn't an event on.

Kind regards

Phil

Hi @Anonymous ,

You can create another measure as below to get it, please find the details in the attachment.

Number of dates which have events = SUMX(VALUES('Date'[Date]),[Measure])

Hi @Anonymous ,

Consider this below example, 

Event    Date

A           11/29/2022

A           11/29/2022

B           11/29/2022

C           11/29/2022

So suppose if  condition is that on 29th Nov 22, A event should occur.

Then you have to create a calculated column in you table as ,

Calculated Column = IF('table1'[Date]="11/29/2022" && 'table1'[Event]="A",1,0)

So you'll get the output as below,

Event    Date                Eventsoccured

A           11/29/2022     1

A           11/29/2022     1

B           11/29/2022     0

C           11/29/2022     0

For getting the distinct count for this you have to use a calculated measure, 

Distinctcount =
CALCULATE(
DISTINCTCOUNT ('table1'[Eventsoccured]),
FILTER('table1','table1'[Eventsoccured]=1)
)

This will solve your issue.
