Same Period Last Month in Line Charts - How to remove non existing days

Hi there,

 

I am tying to create a line chart that shows this month values (sales or whatever) and last month values when the dates of the current selected month are on the x axis.   


I am expecting to see only dates in this chart which have an existing "day" in the previous month. This means data for march should only show days until the 28th since February has only 28 days. 

 

I can get it to work if I use last months dates on the x axis but this creates a confusing hover over meassage.

 The values are present for non consecutive dates (some dates don't have values) and I am using a Calendar Table with consecutive dates for the filtering.

I tried several SPLM calculations which have the result seen above or use the wrong context in which the total amount is copied for all dates.

I watched videos from @marcorusso and others and I read @Greg_Deckler time intelligence blog post but I still don't get it.

Any ideas are appreciated. Here is a pbix file with the example.

Hi @Myagi-Do ,

 

Please try:

Measure_SPLM =
IF (
    DAY ( SELECTEDVALUE ( 'Calendar'[Date] ) )
        = DAY ( EDATE ( SELECTEDVALUE ( 'Calendar'[Date] ), -1 ) ),
    CALCULATE (
        SUM ( same_period[value] ),
        FILTER (
            ALL ( 'Calendar' ),
            [Date] = EDATE ( SELECTEDVALUE ( 'Calendar'[Date] ), -1 )
        )
    )
)

Output:

This worked like a charm. I see what you did there with the if statement and I didn't know the EDATE function before. 

Thanks for the help @v-jianboli-msft
