Calculate ratio

[Anonymous]

Hi,

I need to calculate the ratio of some fields. I have the following data, this is the structure of the data. 

ID	Numbers	Date	Hour
1	2	05-13-2020	10:00
1	1	05-13-2020	11:00
2	3	05-13-2020	10:00
3	3	05-13-2020	10:00
3	1	05-13-2020	11:00

I need to create a new column or measure, don't know whats better to use, to calculate the ratio.

I need the follow numbers

ID	Ratio
1	30%
2	30%
3	40%

I can use a measure with SUM('table1'[numbers]) and then use this in a card to show the total numbers. I can also click here in the desktop version to "show percent of grand total" which will give me 100%. When I to this in a table I get the correct numbers as show above.

But I want to show an average of these ratio's and I just can't manage to do this with measure. Because I need the total numbers of a day of all ID together and divide this with the total numbers of the ID itself. In this way you get the ratio of each ID.

I hope someone can help me with this.

You may use the measure below.

Measure =
DIVIDE (
    AVERAGEX ( VALUES ( Table1[ID] ), CALCULATE ( SUM ( Table1[Numbers] ) ) ),
    CALCULATE ( SUM ( Table1[Numbers] ), ALLSELECTED ( Table1[ID] ) )
)

Thank you both @v-chuncz-msft and @az38 . Both of the solutions works with a measure. 

Is this formula also possible to use as an extra column instead of a measure?

@Anonymous 

yes, it should be fine

You could a default SUM aggregation on Number and use "Show as...Percent of grand total".

@Greg_Deckler Thank you for your reply.

I know I can use a percent of grand total, but I want a measure that's calculation the average of all the ratio's of all ID's. And I can't do that with the "percent of grand total" function. Hope you understand my question, sorry for my garbage English.

Hi @Anonymous 

try a measure

Measure = 
DIVIDE(
CALCULATE(SUM(Table[Numbers]), ALLEXCEPT(Table, Table[ID]) ),
CALCULATE(SUM(Table[Numbers]), ALL(Table) )
)
