Problem using Pareto: accumulated error on repeated values

[MaxViana]

Hello friends!

I need to create a Pareto chart and I'm finding it difficult to create a metric that shows me the cumulative total for each row ordered by a ranking.

I can create the ranking. However, my accumulated value measurement is in error when the line value is repeated.

How to solve this annoying problem?

Olá @MaxViana.

Eu enfrentei um problema similar ao criar um pareto e não conseguia resolver com o rankX. No entanto consegui encontrar uma maneira de "resolver" este problema com uma pequena gambiarra. Para mim deu certo, não sei se seria a solução para você:

 1 - na sua base de dados, adicione uma coluna de index a partir de 1

Feito isso, crie uma nova coluna somando o seu valor [Ocorrências] + o valor da coluna dividido por um valor bem alto, por exemplo 100.000.000 (use um número alto o suficiente para não atrapalhar os teus dados) , utilize esta nova coluna como refêrencia para seu cálculo de pareto.

Hi @MaxViana 

I think your problem is that when your Atual is repeated, you will get the wrong acc.

Ex: Toc... Atual = 9, Acc should be 225+9 = 234 instead of 243.

     Tag... Atual = 9, Acc should be 234+9 = 243.

Is it right?

I think you can achieve your goal by build a ranking column(not a measure) which is not repeated.

Try this measure:

Acc = SUMX(FILTER(ALL('Ocorrencias'),'Ocorrencias'[Rank]<=MAX('Ocorrencias'[Rank])),'Ocorrencias'[Total])

If this reply still couldn't help you solve your problem, please share a sample with me by your Onedrive for Business.

I was not able to do that, my friend RicoZhou. 😭
I don't know how to create a ranking in a column.

I've been struggling with this for a while. I'm almost giving up on making this Pareto.

Would you help me with it?

Hi @MaxViana 

I will use your sample in your new post to have a test, I think you are still confused in the same problem.

Firstly in build a NameRank in Ocorrenicas table.

NameRank = RANKX(Ocorrencias,Ocorrencias[Município Fato],,ASC,Dense)

Then Build new rank measure.

NameRanking = CALCULATE(MAX(Ocorrencias[NameRank]),ALLEXCEPT(Ocorrencias,Ocorrencias[Município Fato]))

NewRanking = 
RANKX(ALL(Ocorrencias[Município Fato]),[Ranking]+[NameRanking]/1000,,ASC,Dense)

Then you can calculate Acc and Acc%by your new rank.

Realize that the problem persists. In the 13th and 14th rank, the cumulative measures still do not work.
