## Creating Arrows to trend values over a certain period of time

Good Morning. So i have a PBI dashboard I created (very amature) and I need some help.

I need to show wheather the value is up or down from the previous month. I know how to add the arrows with conditional formatting, the issue I'm running into is the calculation. I used a previous dashboard as a guide, but the formula to calculate the difference Month over month is not right. Does anyone have the syntax or guidence for how to write this so it work. Right now i currently have a measure created :

"

%_Count_Mom_Var = IF(CALCULATE(SUM('Carc_Rarc_Historical'[Patnum]),ALL(Dates[Date_Id]),FILTER(ALL(Dates),Dates[Date_Rank]=SELECTEDVALUE(Dates[Date_Rank])-1))=0,"", (CALCULATE(SUM('Carc_Rarc_Historical'[Patnum]))-CALCULATE(SUM('Carc_Rarc_Historical'[Patnum]),ALL(Dates[Date_Id]),FILTER(ALL(Dates),Dates[Date_Rank]=SELECTEDVALUE(Dates[Date_Rank])-1)))/CALCULATE(SUM('Carc_Rarc_Historical'[Patnum]),ALL(Dates[Date_Id]),FILTER(ALL(Dates),Dates[Date_Rank]=SELECTEDVALUE(Dates[Date_Rank])-1)))"

and it is calculating zero for every field, so i know its wrong. I just don't know how to fix it.

or if there is an easier way to go about this, I'd appreciate the help

Hi, @Anonymous

You can try the following methods.

``````%_Count_Mom_Var =
IF (
CALCULATE ( SUM ( 'Carc_Rarc_Historical'[Patnum] ),
FILTER ( ALL ( Dates ),
Dates[Date_Rank] = SELECTEDVALUE ( Dates[Date_Rank] ) - 1
)
) = 0,
"",
CALCULATE ( SUM ( 'Carc_Rarc_Historical'[Patnum] )
- CALCULATE ( SUM ( 'Carc_Rarc_Historical'[Patnum] ),
FILTER ( ALL ( Dates ),
Dates[Date_Rank] = SELECTEDVALUE ( Dates[Date_Rank] ) - 1
)
)
)
/ CALCULATE ( SUM ( 'Carc_Rarc_Historical'[Patnum] ),
FILTER ( ALL ( Dates ),
Dates[Date_Rank] = SELECTEDVALUE ( Dates[Date_Rank] ) - 1
)
)
)``````

Is this the result you expect?
