% of days where value is 0

[OZEEE]

I am trying to calculate the % of days where the value is 0.  Below is sample data. Underlying dataset has multiple values each day. I need to know if the total of all values for a day is above 0. Then what percent of days are above 0

Hi @OZEEE 

See this picture, at the left is my data table, with 10 rows, and June 2 has a report of 0 and 2. There are actually 8 distinct dates, so my measure [Distinct Values] gives you the denominator. Then for the numerator, I used SUMMARIZE() to group by date, so we lost one day = 0. Use the measure [Summarize] for the numerator. I put the measure [Percent of Days 2] in the editing bar at the top. ([The Percent of Days] is superseded by the [Percent of Days 2].)

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

Hi @OZEEE ,

Rather than assuming 365, you can use this measure to count the unique entries in your date column for the denominator.

Distinct Values = COUNTROWS(DISTINCT(AboveZ[DOS]))

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

@OZEEE ,

Try this... If you use the numerator as another measure, it will give you the count.

Hi Nathan,

The problem with this is that each row isn't a distinct date. For example, I could have two values on 6/1/2018, but I still need that to count as 1 "non-zero day". The dates with more than than one value will distort the calculation I am looking for.  I guess another way to word it is, "What percent of the time is the sum of a day 0 throughout the year"

Any thoughts?  The denominator should be 365 when analyzing a year's worth of data

Hi @OZEEE ,

Tell me more. On 6/1/2018 you say that you can have two values. Could they both be zero, could one be zero and the other not? What happens then?
