How to calculate percentage of data selected by country

[elac]

Hi there,

I have two tables

device_lookup(device name, model, country)

n1, a, US

n2, a, US

n3, b, US

n4, a, UK

deviceType_lookup(model, manufacturer)

a, lenovo

b, dell

c, acer

with slice to select the mode, how to caculate the percentage of selected devices by country.

ie. if user selected mode = a, i would like to get 

US, 66.66%

UK, 100%

Thank you in advance!

Hello  amitchandak,

First, thank you so much for answer.

I tried both measures but it didn't give me the expected result.

device% = divide(countrows(device_lookup), calculate(countrows(device_lookup), removefilters(deviceType_lookup[model]) ) )

device%_2 = divide(countrows(device_lookup), calculate(countrows(device_lookup), all() ) )

However, neither was giving the correct answer. 

method 1 always return 100%

method 2 doesn't group on country, it acutally get the percentage on all devices in device lookup

Any thoughts? Any help is appreciated!

Hi @elac ,

I create a file for your reference.

The measure I used:

percentage = var _count1=CALCULATE(COUNT('device_lookup'[model]),FILTER(ALLSELECTED(device_lookup),[country]=MAX('device_lookup'[country])))
 var _count2=CALCULATE(COUNT('device_lookup'[country]),FILTER(ALL(device_lookup),[country]=MAX('device_lookup'[country])))
 return DIVIDE(_count1,_count2)

Hello Stephen,

This is terrific. It solves my problem perfectly.

If you don't mind, could you tell what is wrong with my original measure?

device%= divide(countrows(device_lookup), calculate(countrows(device_lookup), removefilters(deviceType_lookup[model]) ) )

Thank you so much!

@elac , Try a measure like

divide(countrows(Table), calculate(countrows(Table), removefilters(deviceType_lookup[model]) ) )

or

divide(countrows(Table), calculate(countrows(Table), all() ) )
