Calculate symmetric mattrix

[Anonymous]

Hi experts,

I'm calculating a symmetric matrix with following tables (It is just a portion of the data):

Sport A Label	Sport B Label	QtUsersIntersection	QtUsersSportOther
Baloncesto	Balonmano	16	288
Baloncesto	eSports	29	288
Baloncesto	Fútbol Sala	262	288
Balonmano	Baloncesto	16	30
Balonmano	eSports	5	30
Balonmano	Fútbol Sala	22	30
eSports	Baloncesto	29	50
eSports	Balonmano	5	50
eSports	Fútbol Sala	29	50
Fútbol Sala	Baloncesto	262	294
Fútbol Sala	Balonmano	22	294
Fútbol Sala	eSports	29	294

The column "QtUsersSportOther" is comming from another table, and looks like this:

sport	QtUser
Baloncesto	288
Balonmano	30
eSports	50
Fútbol Sala	294

My measure is as follows :

% us = CALCULATE(DIVIDE(SUM(SportsIntersection[QtUsersIntersection]);Sum(SportsIntersection[QtUsersSportOther]); 0))

and I want to create a symetric matrix. The output I'm getting is:

However, as it is a symetric matrix, It should look like this:

I've created this ilustration to explain what I have in mind, but I can't get to translate to DAX, so I need help in this:

From the table above, from sport A ("Baloncesto") and SportB ("Futbol Sala"); and "Balonmano" and "Futbol Sala"; and "eSport" and "Futbol Sala" are already calculated, fill with blank all the rows related to the column SportA to "Futbol Sala" and so on.

I'm really stuck with this. Any suggestion?

Hope I've made myself understood.

Sure.  Is your visual always going to have the fields in alphabetical order? If so, you just need a minor change to your measure. Otherwise, you'll need some sort of other ranking system to let PowerBI know the order of the categories.

% us = CALCULATE(DIVIDE(SUM(SportsIntersection[QtUsersIntersection]);Sum(SportsIntersection[QtUsersSportOther]); 0); FILTER(SportsIntersection; SportsIntersection[Sport A Label]< SELECTEDVALUE(SportsIntersection[Sport B Label])))
