Pareto with duplicate values

I'm trying to show a Pareto chart but I have serveral duplicated values; this results in a jagged step function, as PBI is rolling up the multiple occurances as one. For example:

greggbb_1-1629929167421.png

 

Any ideas to show this properly?  For example instead of 9%, 25%, 25% this should show 9%, 17%, 25%. 

 

My cumulative percent function is just rolling up the Score by Business Risk:

Business Risk Cumulative =
var thisProduct=[Score Measure]
var allProducts=calculate([Score Measure],all(JoinMatrix[Business Risk]))
return
calculate([Score Measure],filter(all(JoinMatrix[Business Risk]),[Score Measure]>=thisProduct))/allProducts

This one can be done with a two column rank using a pattern like this. 

 

First make a calculated column to get a rank based on the Risk category with an expression like this.  It will give you rank your categories alphabetically.

 

ForRiskRank = var thisvalue = Risk[Risk] return RANKX(Risk, Risk[Risk], thisvalue,DESC)
 
Then create a measure like this (replace Risk with your actual table name, and correct column/measure references).  The alphabetical rank is divided by 1000 so that result can't affect the overall ranking based on risk.  Adapt as needed.
 
Cumulative Risk Pct =
VAR thisvalue =
    MIN ( Risk[Value] )
VAR thisriskrank =
    MIN ( Risk[ForRiskRank] ) / 1000
VAR summary =
    ADDCOLUMNS (
        ALLSELECTED ( Risk[Risk] ),
        "cValue"CALCULATE ( MIN ( Risk[Value] ) ),
        "cRanked",
            CALCULATE ( SUMX ( Risk, Risk[Value] + Risk[ForRiskRank] / 1000 ) )
    )
VAR totalvalue =
    SUMX ( summary, [cValue] )
VAR cumulativevalue =
    SUMX ( FILTER ( summary, [cRanked] >= thisvalue + thisriskrank ), [cValue] )
RETURN
    DIVIDE ( cumulativevaluetotalvalue )
 
 
I made a simple table to test it out below.

Thanks Pat, but it's returning 100% across the board.  I realized that I didn't mention that the dataset is one level below "Business Risk" with a subcategory called "Vulnerabily" so I wonder if this is part of the issue, i.e. my raw data looks like this:

 

Business RiskVulnerabilityScoreColScore MeasureBusiness Risk CumulativeOverall TotalCumulative Risk Pct
Customer Order Submission failureDenial of Service/Network failure101012%217412%
PII DisclosureSocial Engineering/Phishing161613%217413%
Order fulfilment stoppageRansomware/Malware151517%21748%
Order Processing stoppageRansomware/Malware151517%217417%

 

Interestingly in my chart I'm getting 100% when I look at Business Risk alone (it's the dark blue line, the light blue is my original metric):

However if I filter on any aspect of Vulnerability your metric works perfectly!  Is there something I can adjust so it will work at both levels?

 

Thanks,

Hi @greggbb ,

 

Try the following formula:

 

 

Order = 
VAR RoundedSales = [Score Measure]
RETURN IF (
    HASONEVALUE ( JoinMatrix[Business Risk] ) && ( RoundedSales > 0 ),
    VAR CustomersWithRankedName =
        ADDCOLUMNS (
            ALLSELECTED ( JoinMatrix ),
            "@NameRanked", RANKX ( ALLSELECTED ( JoinMatrix ), JoinMatrix[Business Risk],, DESC, DENSE )
        )
    VAR MaxCustomerNameRanked =
        MAXX ( CustomersWithRankedName, [@NameRanked] )
    VAR LookupTable =
        ADDCOLUMNS (
            CustomersWithRankedName,
            "@CustomerSales",
                [Score Measure] * MaxCustomerNameRanked + [@NameRanked]
        )
    VAR CurrentName =
        SELECTEDVALUE ( JoinMatrix[Business Risk] )
    VAR CurrentNameRanked =
        RANKX ( ALLSELECTED ( JoinMatrix ), JoinMatrix[Business Risk], CurrentName, DESC, DENSE )
    VAR CurrentValue = RoundedSales * MaxCustomerNameRanked + CurrentNameRanked
    VAR Ranking =
        RANKX ( LookupTable, [@CustomerSales], CurrentValue,, DENSE )
    RETURN
        Ranking
)
Business Risk Cumulative = 
var thisProduct = [Score Measure]
var allProducts = calculate( [Score Measure], all(JoinMatrix[Business Risk] ) )
var maxCurrentRank = [Order]
var rankTable = FILTER( ALLSELECTED(JoinMatrix[Business Risk]), [Order] <= maxCurrentRank)
return CALCULATE([Score Measure], rankTable) / allProducts

Thanks Winniz, but that isn't working either.  In fact it's all coming in at 98%:

This has become oddly complicated for something that I can easily build in Excel.  I'm going to look for a different visualization to get my point across as it doesn't seem Power BI can handle the math when duplication is involved.

 

Thanks,

Gregg

 

Hi @greggbb ,

 

Could you please share your PBIX file without sensitive data? In my test data, it works well.
