Create line graph for only Month end values based on date slicer

Step 0: I use your data below.

Step 1: I add a 'Month' column and a 'Flag' column.

    Month = MONTH([Date])

    Flag = IF([Date]=CALCULATE(MAX(DATA[Date]),ALLEXCEPT('DATA','DATA'[Month])),1,0)

Step 2: I make a graph and set 'Flag' filter.

Hi, Anonymous 

Regarding the issue you raised, my solution is as follows:

1.First I have created the following table and the column names and data are the data you have given:

2.Create calculated column references:

LastWorkdayOfMonth = 
VAR LastDay = EOMONTH('Table'[Date], 0)
VAR LastWorkday = 
    SWITCH(
        WEEKDAY(LastDay, 2),
        6, LastDay - 1,  
        7, LastDay - 2,  
        LastDay          
    )
RETURN LastWorkday

3. Below are the measure I've created for your needs:

MEASURE A = 
VAR LastDay1 =
    EOMONTH ( MAX ( 'Table (2)'[selcet] ), 0 )
VAR LastDay2 =
    EOMONTH ( MAX ( 'Table (2)'[selcet] ), -1 )
VAR LastWorkday1 =
    SWITCH ( WEEKDAY ( LastDay1, 2 ), 6, LastDay1 - 1, 7, LastDay1 - 2, LastDay1 )
VAR LastWorkday2 =
    SWITCH ( WEEKDAY ( LastDay2, 2 ), 6, LastDay2 - 1, 7, LastDay2 - 2, LastDay2 )
RETURN
    IF (
        MAX ( 'Table (2)'[selcet] ) = LastWorkday1,
        CALCULATE (
            SUM ( 'Table'[Metric A] ),
            'Table'[LastWorkdayOfMonth] = MAX ( 'Table (2)'[selcet] )
        ),
        CALCULATE (
            SUM ( 'Table'[Metric A] ),
            'Table'[LastWorkdayOfMonth] = LastWorkday2
        )
    )

Measure B = 
VAR LastDay1 =
    EOMONTH ( MAX ( 'Table (2)'[selcet] ), 0 )
VAR LastDay2 =
    EOMONTH ( MAX ( 'Table (2)'[selcet] ), -1 )
VAR LastWorkday1 =
    SWITCH ( WEEKDAY ( LastDay1, 2 ), 6, LastDay1 - 1, 7, LastDay1 - 2, LastDay1 )
VAR LastWorkday2 =
    SWITCH ( WEEKDAY ( LastDay2, 2 ), 6, LastDay2 - 1, 7, LastDay2 - 2, LastDay2 )
RETURN
    IF (
        MAX ( 'Table (2)'[selcet] ) = LastWorkday1,
        CALCULATE (
            SUM ( 'Table'[Metric B] ),
            'Table'[LastWorkdayOfMonth] = MAX ( 'Table (2)'[selcet] )
        ),
        CALCULATE (
            SUM ( 'Table'[Metric B] ),
            'Table'[LastWorkdayOfMonth] = LastWorkday2
        )
    )

4.Here's my final result, which I hope meets your requirements.
