Cumulative Measure - Set static Start Date

[Keha]

Dear experts,

I have run into a problem revolving around cumulative measures and I was hoping that you would be able to assist. What I am trying to achive is to display a bouncerate change over time (days 0 - 31; in %) in a graph. I have reached that result with a cumulative measure and the ALLSELECTED Filter. However with this making the graph beginn with 0 bouncerate. I would like it to start from the End Value of the previous day so I can see a clear negative/positive movement.

The Measure I use is the following. I think I have to switch out the ALLSELECTED Filter, or Add something to it?

Test1 = IF (

    MIN ( 'DateDimension'[Date] )

        <= CALCULATE ( MAX ( 'Table'[Date] ); ALL ( 'Table' ) ); 

CALCULATE (

    SUM('Table'[Bounces])/SUM('Table'[Sessions]);

    FILTER (

        ALLSELECTED(Datedimension);

        'Datedimension'[Date] <= MAX ( 'Datedimension'[Date] )

            && 'Datedimension'[Date] <= TODAY()

    )

)

)

I think it could workout if I use the following. With this the Graph is starting with a value. However, the underlying Data is taken from the whole Dataset and not only the selected year (e.g. 2017). Is there a way to add some sort of start Date to it which would be the starting date of the year (e.g. 2017)?

Test1 = IF (

    MIN ( 'DateDimension'[Date] )

        <= CALCULATE ( MAX ( 'Table'[Date] ); ALL ( 'Table' ) ); 

CALCULATE (

    SUM('Table'[Bounces])/SUM('Table'[Sessions]);

    FILTER (

        ALL(‚Datedimension‘ [Date]);

        'Datedimension'[Date] <= MAX ( 'Datedimension'[Date] )

            && 'Datedimension'[Date] <= TODAY()

    )

)

)

I have attached two Screenshots to visualize the problem attached.

Thanks so much in advance! If you need more data please let me know.

I think I got it to work with:

Test1 = IF (

    MIN ( 'DateDimension'[Date] )

        <= CALCULATE ( MAX ( 'Table'[Date] ); ALL ( 'Table' ) ); 

CALCULATE (

    SUM('Table'[Bounces])/SUM('Table'[Sessions]);

    DATESYTD( Datedimension[Date] ) ) 

)

Thank you anyways!!
