display values with latest date on map

[abdalla]

hello,

I have a map with alot of points that i need to display the values of pressure that correlate to the latest active month date.

This is how my data looks like

i havent made any measures or any columns or tables. 

My apologies for limited data but my data is very sensitive. My request is how i can add the latest info  in the same table without creating a separate table.

The data plots column is just a concatenation between the shut in pressure column and the active month column 

If you would like to access the file 

feel free to follow my link and download the file

HI @abdalla,

I'd like to suggest you write a formal with a variable to extract the last date based on the current Well field value.
Then you can use the current Well and lastdate as conditions to find out corresponding pressure values:

formual =
VAR _lastdate =
    CALCULATE (
        MAX ( Table[Active Month] ),
        ALLSELECTED ( Table ),
        VALUES ( Table[Well] )
    )
RETURN
    CALCULATE (
        MAX ( Table[Psi] ),
        FILTER ( ALLSELECTED ( Table ), Table[Active Month] = _lastdate ),
        VALUES ( Table[Well] )
    )
