Summarizing count and percentage of string values in matrix

[meritaten]

Hello,

I have search everywhere for a solution to my problem, and I'm sure it's an easy fix, I just don't know the correct way to describe what I need to do.

I have a table with information with unique IDs. Four columns in the table include string values that I want to show in a matrix. I want to summarize those four columns with a count and percentage of total.

For example:

personID	parent	gparent	sibling
123	parent1	gparent1	sibling1
234	parent1	gparent1
345		gparent1
456

shows as in matrix:

	Count	Percentage
parent	2	50%
gparent	3	75%
sibling	1	25%

I have learned to do quite a bit in PowerBI, but this one has me baffled.

Thank you!

@meritaten 

you can try to select the first column and unpivot other columns  in PQ

then create two measure

count = countx(FILTER('Table (2)','Table (2)'[Value]<>""),'Table (2)'[Value])

percentage = [count]/COUNTROWS('Table (2)')

Thank you! This is a feature I wasn't aware of and it did answer my question, but with one minor tweak. After unpivoting, the rows with null values were removed from the result, which skewed my percentages. I simply then adjusted the second measure to calculate using the total number of rows from the master table. 

Would you tell me how you unpivoted and retained the blank rows?

Thank you for teaching me one more feature of PQ!

select the personID column and unpivot other columns

Okay, got it! The issue was that the cells without data were null, not blank in my dataset. I converted them to blank and now it works perfectly!

Thank you!
