Help with a measure

I have 2 tables, which for the purposes of my question I have made very basic:

DJsummers_2-1615392183743.png

 

The table on the left will change each day - the day will change and the temperature will change.

 

The table on the right is the standard of which I want the temperature to be as close to as possible, dependant on what day it is (it usually goes up to 50 days)

My question - is it possible to create a meaure where I can subtract the standard target temp from the actual temp that changes each day? For example, tomorrow will be Day 2 for the left table and let's say the temperature will be 34, can I then get it to subtract the value from Day 2 on the right table? (34-32.30=1.7)

Thanks in advance!
Dan

Hi @DJsummers ,

 

You could try a measure like this, where 'aTable' is your single changing value, and 'bTable' is your target table.

_tempDiff = 
VAR todayDay = MAX(aTable[day])
RETURN
CALCULATE(
    MAX(aTable[temp]) - MAX(bTable[temp]),
    FILTER(
        bTable,
        bTable[day] = todayDay
    )
)

 

This gives me the following output:

@DJsummers , Create a new column in table 2(standard)

 

standard[temperature] - maxx(filter(changes, changes[day] = standard[day]),changes[temperature])

 

or a measure

measure =
var _max = maxx(allselected(changes), changes[day])
return
maxx(filter(standard, standard[day] =_max),standard[temperature]) - maxx(filter(changes,changes[day] =_max),changes[temperature])
