Pareto Chart

[qnnn8]

Hi all,

I am working on a pareto chart but am facing an error whereby cumulative summing doesn't work when there are categories with the same count as seen below

  Cat A w/ sub-categories with same count                                   Cat B w/ sub-categories of unique counts

Below is the code used for the line measure

Pareto Measure = 
VAR TotalCount = CALCULATE(
        DISTINCTCOUNT('Aircraft Records'[Investigation  Report No. (INV)]),
        FILTER(
            ALLSELECTED('Aircraft Records'),
            'Aircraft Records'[Investigation  Report No. (INV)] <> BLANK()
        )
    )

VAR currentCount = 
    CALCULATE(
        DISTINCTCOUNT('Aircraft Records'[Investigation  Report No. (INV)]),
        FILTER(
            'Aircraft Records',
            'Aircraft Records'[Investigation  Report No. (INV)]<> BLANK()
        )
    )


VAR summarisedtable =
    SUMMARIZE(
        FILTER(
            ALLSELECTED('Aircraft Records'),
            'Aircraft Records'[Investigation  Report No. (INV)] <> BLANK()
        ),
        'Aircraft Records'[Sub-Root Cause],
        "CountInv",
        DISTINCTCOUNT('Aircraft Records'[Investigation  Report No. (INV)])
    )

VAR cumulative = sumx(filter(summarisedtable, [CountInv] >= currentCount),[CountInv])

return cumulative/TotalCount

Any help would be very much appreciated!!

@qnnn8 , Please use Window function for that, yiu can easily break ties using order by

Cumm = CALCULATE( DISTINCTCOUNT('Aircraft Records'[Investigation Report No. (INV)]), Window(1,ABS,0,REL, ALLselected('Aircraft Records'[category]),ORDERBY( DISTINCTCOUNT('Aircraft Records'[Investigation Report No. (INV)]),desc,'Aircraft Records'[category], asc )))

Pareto Analysis Again, 80% of sales, Order by Measure when REL position is used: https://youtu.be/GpoITi_tRIw

Or try with Range Visual level funtion

Hi Amit,

I've tried the formula that you have provided but the values are not correct.
