Need help with DAX

Hello Experts,

 

I have a table as mentioned below:

 

DateFieldValueCategory
01-01-20201A
02-01-202010A
03-01-2020100A
04-01-2020100A
03-01-2020100B
04-01-2020100B

 

I want to plot accumulated values on a graph. The catch here is, if i select a period of 01-Jan-2020 to 04-Jan-2021 and plot two lines for Categories A and B, the value of the first datapoint(one with minimum date) for each category should be subtracted from each and every data point(including the first point; thus making it zero). The dax mentioned below gives me the result when i browse the values by category:

 

Cumulative value =
CALCULATE(
SUM('MyTable'[Value]),
FILTER(
ALLSELECTED('MyTable'[DateField]) ,
ISONORAFTER('MyTable'[DateField], MAX('MyTable'[DateField]), DESC)
)
)

-

CALCULATE(SUM('MyTable'[Value])
,FILTER(ALLSELECTED('MyTable'[DateField]), 'MyTable'[DateField] = CALCULATE(MIN('MyTable'[DateField]),ALLSELECTED('MyTable'[DateField]))))

 

Although, this measure does not work when i try to browse the value at an overall level and not by category.

I could group it by category to get the sum of the values, but subtracting first value for each group is where i am stuck at.

 

Asking you experts for your help.

 

Kind Regards,

Chetan

    Anonymous , Not sure, I got it completely. Based on what I got Try like

     

    Cumulative value =
    CALCULATE(
    SUM('MyTable'[Value]),
    FILTER(
    ALLSELECTED('MyTable'[DateField]) ,
    ISONORAFTER('MyTable'[DateField], MAX('MyTable'[DateField]), DESC) && 'MyTable'[Category] ="A"
    )
    )

    -

    CALCULATE(
    SUM('MyTable'[Value]),
    FILTER(
    ALLSELECTED('MyTable'[DateField]) ,
    ISONORAFTER('MyTable'[DateField], MAX('MyTable'[DateField]), DESC) && 'MyTable'[Category] ="B"
    )
    )
