DOW Filter Mon, Tue, Wed... Each on Its Own Visual (Current Week)

You might be able to use a relative date slicer for this too using this calendar week.

Hi samdep 

I think you need to build calendar and add a custom weeknum column and year column in it. If you use weeknum directly, you will get wrong weeknum at the end of the previous year and the beginning of the next year.

For example: 

In my Sample I let week start on Sunday.

2020/12/31,2021/01/01,2021/01/02 are in the same weeknum, but weeknum function will give you 53 in 2020 and 1 in 2021. It's wrong result.

Firstly build a calendar table by dax and add calculated columns in it to get correct weeknum and year.

Date = 
ADDCOLUMNS (
    CALENDAR ( DATE ( 2019, 01, 01 ), DATE ( 2021, 12, 31 ) ),
    "Year", YEAR ( [Date] ),
    "Month", MONTH ( [Date] ),
    "WeekNum", WEEKNUM ( [Date], 1 ),
    "WeekDay", WEEKDAY ( [Date], 1 ),
    "MonthName", FORMAT ( [Date], "MMMM" ),
    "DayName", FORMAT ( [Date], "DDDD" )
)

Calculated columns:

ISO 8601 WeekNum = 
VAR _COUNT0 =
    CALCULATE (
        COUNTROWS ( 'Date' ),
        FILTER (
            'Date',
            'Date'[Year] = EARLIER ( 'Date'[Year] )
                && 'Date'[WeekNum] - 1 = 0
        )
    )
VAR _BASENUM1 =
    IF ( _COUNT0 < 7, 'Date'[WeekNum] - 1, 'Date'[WeekNum] )
VAR _ISO_8601_WeekNum =
    IF (
        WEEKDAY ( DATE ( 'Date'[Year] - 1, 01, 01 ) ) <> 1
            && 'Date'[Year] = 'Date'[Year]
            && _BASENUM1 = 0,
        WEEKNUM ( DATE ( MIN ( 'Date'[Year] ), 12, 31 ), 1 ) - 1,
        _BASENUM1
    )
RETURN
    _ISO_8601_WeekNum

WeekYear = 
VAR _COUNT0 =
    CALCULATE (
        COUNTROWS ( 'Date' ),
        FILTER (
            'Date',
            'Date'[Year] = EARLIER ( 'Date'[Year] )
                && 'Date'[WeekNum] - 1 = 0
        )
    )
VAR _BASENUM1 =
    IF ( _COUNT0 < 7, 'Date'[WeekNum] - 1, 'Date'[WeekNum] )
RETURN
IF(_BASENUM1 = 0,'Date'[Year] -1,'Date'[Year])

Then you can relate this date table with your Data table by date columns. 

 Add a Flag column in your Data table. 

Flag =
VAR _TodayWeeKNum =
    CALCULATE (
        MAX ( 'Date'[WeekNum] ),
        FILTER ( 'Date', 'Date'[Date] = TODAY () )
    )
VAR _TodayWeeKYear =
    CALCULATE (
        MAX ( 'Date'[WeekYear] ),
        FILTER ( 'Date', 'Date'[Date] = TODAY () )
    )
RETURN
    IF (
        RELATED ( 'Date'[WeekNum] ) = _TodayWeeKNum
            && RELATED ( 'Date'[WeekYear] ) = _TodayWeeKYear,
        1,
        0
    )

My Date Table:

Add Flag column into Page Level Filter Field and set it to show items when value equal to 1.

Result is as below.
