Measure for Percentage difference

[Zaynah16]

Hi everyone 

Please could someone help me with a measure 

I need to calculate the percentage difference between two status's ( on track = 1 and at risk = 2) 

Calculation 

Total number % number of green(1) = percentage of green 

Total number % total number of red (2) = percentage of red

percentage of green minus percentage of red = total score 

Data Stucture 

Tatble name : RAG status 

Column 1 : Item 

Column 2 :Status

Column 3: Score 

Thanks in advance

@SpartaBI 

Sample data - i need a dax calc/ measure to calculate the percentage score. 

eg. 

289 items 

79 are on track 

60 are at risk 

I need a percentage total score of the on track minus at risk 

PILLAR	Business Unit	Section	Sub Section	Item	Status	Score
					On track	1
					On track	1
					On track	1
					Lagging	2
					Lagging	2
					Lagging	2
					Lagging	2
					No data	0
					No data	0
					No data	0
					No data	0
					At risk	3
					At risk	3
					At risk	3
					At risk	3
					At risk	3
					At risk	3

@Zaynah16 I'm not sure what do you mean by 'percentage total score' 🙂
Anyway I took a guess, maybe this will anyway show you the way:

_Measure = 
VAR _pct_on_track = 
DIVIDE(
	CALCULATE(
		SUM(RAG status[Score]),
		RAG status[Status] = "On Track"
	),
	CALCULATE(
		SUM(RAG status[Score]),
		REMOVEFILTERS(RAG status[Status])
	)
)
VAR _pct_at_risk = 
	DIVIDE(
		CALCULATE(
			SUM(RAG status[Score]),
			RAG status[Status] = "At Risk"
		),
		CALCULATE(
			SUM(RAG status[Score]),
			REMOVEFILTERS(RAG status[Status])
		)
	)
RETURN
	_pct_on_track - _pct_at_risk

Hi @SpartaBI 

Another quiestion please

I've got a graph with the above data however when i click on the No data or lagging on the grapgh it gives me a percentage. How do i exclude lagging and no data and only have a result when clicking on the on track or at risk. if possible could we have it return N/A when clicking on the no data and lagging

@Zaynah16 not sure what you need exactly. Can you supply sample data (copy paste of few rows) and the desired result hard coded after +  the logic for that result.
