## How to calculate percentage of data selected by country

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!

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  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!

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() ) )
