Calculate symmetric mattrix

Hi experts,

 

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

 

Sport A LabelSport B LabelQtUsersIntersectionQtUsersSportOther
BaloncestoBalonmano16288
BaloncestoeSports29288
BaloncestoFútbol Sala262288
BalonmanoBaloncesto1630
BalonmanoeSports530
BalonmanoFútbol Sala2230
eSportsBaloncesto2950
eSportsBalonmano550
eSportsFútbol Sala2950
Fútbol SalaBaloncesto262294
Fútbol SalaBalonmano22294
Fútbol SalaeSports29294

 

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

sportQtUser
Baloncesto288
Balonmano30
eSports50
Fútbol Sala294

 

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:

expected tab.png

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.

Re: Calculate symmetric mattrix

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])))
