Sum over current week

Hi everybody,

 

I want to create a simple measure but just can't figure out how to write it properly. Here we go:

 

Let#s say I have a table with two columns:

 

Date    |    Logged in

1.1.2018   |    2

2.1.2018    |    5

3.1.2018    |    6

...

 

So basically a list with people who have been logged into my app on which days.

 

Now I want to create a line chart that shows me the sum of all logins always for the current week. But only for the current week, not counting in any logins from before the start of the week.

 

y axis: # Logins

x axis: Mon, Tue, Wed, Thu, Fri, Sat, Sun (from a separate date table)

 

That means the line chart is always going up.

 

The problem which I can't overcome is, that I don't know how to retrieve the start of the week date for every day of the week. I tried something like this, but it doesn't work:

 

# Logins for current week = 
CALCULATE(
	COUNTROWS('Logins'),
	FILTER('Logins',
		'Calendar'[Date] <= MAX('Calendar'[Date]) &&
        'Calendar'[Date] >= MIN(ALL('Calendar'[Date]))
	)  
) + 0

To replicate your problem I have created a table with a date field and a loggedin field that is populated with numbers.

The following measures will give you the sum of the logged in values only for the week of the date set in the _Today Variable. If you want this to be the current date then set the variable to be equal to UTCTODAY()

 

Current Week = 
VAR _Today =
    DATE ( 2018, 1, 8 )
VAR _StartOfWeek =
    _Today - WEEKDAY ( _Today, 2 ) + 1
VAR _EndOfWeek =
    _Today
        + ( 7 - WEEKDAY ( _Today, 2 ) )
RETURN
    IF (
        MAX ( Table1[date] ) >= _StartOfWeek
            && MAX ( Table1[date] ) <= _EndOfWeek,
        SUM ( Table1[loggedin] ),
        BLANK ()
    )
