Subtraction between yesterday's maximum and today's maximum.

I need a measure that will return the difference between yesterday's max and todays max

so this is my input:

table name: netusage

Zrzut ekranu 2020-11-20 163240.png

 

output example:

18.11.2020        no data - i dont care

19.11.2020        10300-10166 = 134

20.11.2020        10713-10300 = 413

 

tried something like that:

 

todays_maximum = 
CALCULATE(
MAX(netusage[Traffic]),
netusage[Date] = TODAY()
)

ysterdayss_maximum = 
CALCULATE(
MAX(netusage[Traffic]),
netusage[Date] = TODAY()-1
)

sorry, I didn't consider the time part. That will affect the result. I create a new date column and slightly change the DAX.

you can try to create a measure

    Measure = 
    VAR yesterday=maxx(FILTER(all(netusage),'netusage'[Date]=SELECTEDVALUE('netusage'[Date])-1),netusage[Traffic])
    return if(ISBLANK(yesterday),BLANK(),max(netusage[Traffic])-yesterday)

Thanks for the quick reply, I just tried it but the measure doesn't return any value, maybe I'm doing something wrong.
