How can i find the average of each row?
I need to calculate the average of category 1 to 5 for Location A and B and C and so on.
Problem 2: I need to calculate the of all columns in row 10
I tried average, averagea and average but to no avail.
Option-1: You unpivot data and your category values will comes in row per category. Now you can easily calculate the average per location.
Option-2: do something very static like: (cat1+cat2+cat3+cat4+cat5)/5

I am having an issue using the Distinctcount function in DAX. I have a table with a total of 1,154,493 rows. I have a measure created to count the number of distinct values in column 1. I have another measure created to count the number of distinct values in column 1 with filters. I have a 3rd and final measure created to count the number of distinct values of column 1 with different filters. The issue I am running into is the count of measure 2 + measure 3 should equal measure 1 however added together they are GREATER than the value of measure 1 which is just a grand total. How is this possible? Unfortunately I can't share the table but below is the code I am using for the two measures:
Measure1=distinctcount('Table1'[Column1])
Measure2=calculate(distinctcount('Table1'[Column1]),'Table1'[CTest] = 1,'Table1'[CTest2] = "07")
Measure3=calculate(distinctcount('Table1'[Column1]),'Table1'[CTest] = 2,'Table1'[CTest2] = "07")
I am at a loss. Thank you in advance!!
For troubleshooting you should identify values of Column1 with Measure2 and Measure3 > 0, those are being added twice.
I am trying to get my head around DAX and am struggling. I have a PowerBI Matrix in which I need to calculate the average of a measure. The measure is '% of population' and on the surface it appears to work exactly as expected.
It calculates correctly in the top matrix for the two levels and also summarises correctly in the bottom table.
As an example, I have highlighted in red the order of calculations for "A3"
For the record the % population is set to
% of Population = sum(Data[Value])/sum('Level'[Population])
The problem occurs when I filter on the Country and only select Country 2...
Country 2 does not have data for "D13". Although the Values sum up correctly (170), the Sum of the Population includes the 300 from the missing D13 row making a total of 600 and the '% population' of 28.33% (instead of 170 / 300 = 57%)
I am happy to turn off the group totals in the top grid so that the 28.33 does not show; so my real problem is actually with the bottom grid.
I think I need a new measure to be displayed in the bottom grid. I think it simply needs to sum up the values and divide by the sum of the populations - but only when the value is present. How do I do that?
Or am I totally on the wrong track and there is an obvious answer that I am missing?
The PowerBI file can be downloaded from here
Thanks in advance.
The reason this is happening is that the Country table does not filter the Level table in the relationship diagram since they both only filter one way to the Data table and there are no other relationships.
Without changing your data model, one way to fix this in DAX is to specify that you only want to count Population where Level[LevelId] matches a Data[SecondLevelId] in your current filter context.
Population =
DIVIDE (
SUM ( Data[Value] ),
CALCULATE (
SUM ( 'Level'[Population] ),
'Level'[LevelId] IN VALUES ( Data[SecondLevelId] )
)
)
I've started to manage PowerBi from a couple of weeks so i'm a little bit confused about some things.
My problem is that i need a Matrix in my dashboard with percent values but i want the total in number value because the total of a percent of row shows me always 100% and i dont know about the number i'm working
This is my Matrix with percentage values
This is how i want the total of row returns me but with the columns values ins percentage
I've tried to make a measure counting the values
COUNT(OPSRespuestas[answer])
After that turn off the total of rows and add this measure to the values in my matrix but this is what i get
This is my table after trying add a measure with the total
It returns me the total for each of the columns and not the total of all my rows.
These are the tables i'm working with
This my top header values
This is my left header values
The answer column is what i need to count
This is my relationship between this 3 tables although i have many more intermediate table aside from this 3 as you're going to see in the next picture:
My relationship tables
So finally what i need is that this matrix shows me the total of answer in percentage for each of departments and group of questions and then show me total by department but with number value
The problem you are experiencing has to do with context. Each row is seen as it own total population hence the 100% total. Each column in this row is evaluated against the total of that row to provide a percentage value.
In addition to adding a custom measure to replace the total, you could also consider computing a percentage against the grand total of all dimensions. This means that each cell gets evaluated against the the total of all rows and columns. In this ways the cell value would change compared to your first table but the row total does not evaluate to 100% anymore.
SUM ( [Value] ) / CALCULATE ( SUM ( [Value] ) ; ALL ( 'Your Table' ) )
I have one column with scores and need to calculate the count of rows at or below the median score of the column.
I tried the below formula but it appears I'm not allowed to use Median as a filter option.
Calculated Column = if('Table'[Score] < MEDIAN('Table'[Score]),1,0)
I was then just going to subtract the sum of the above from the total row count.
Any help would be appreciated.
Thanks
The Solution :-
I started with something like this,
**Table1**
Score
1
2
3
4
5
6
7
8
I then created a Measure Called as Median with something like this,
Median = CALCULATE(MEDIAN(Table1[Score]),ALL(Table1))
Then, the below step is optional if you want to use in a table/graph to pick the outlier :-
? Below Median = (IF(SELECTEDVALUE(Table1[Score])<[Median],1,0))
Now, to calculate scores below Median, I used something like this :-
# of Scores Below Median = CALCULATE(COUNTROWS(FILTER(Table1,Table1[Score]<[Median])))
These allowed me to generate something like below,
Kindly accept the answer if it helps and if it doesn't please let me know.
you are never allowed to use Measures (Calculated Fields) (in your case Median) in a column calculation.
Try to store the median in one column for every row (same value).
So you have to use calculated column (median) = .. for the median first and then you can use this threshold in your original formal instead of median.
I am doing a rolling 12 month avarage over a specifik sum that are a calculated column if that matter? and my count over 12 month returns 355 day?
My sum column is [Volume]
I have a Calendar Table that are set up accordingly to a hierarchy as picture show below and more,
my code for the rolling avarage is,
12M tonnage Avarage =
CALCULATE(
SUM(STOWAGEACTUAL[VolyMton]);
DATESINPERIOD('Calendar'[DATE]; LASTDATE('Calendar'[DATE]);12;MONTH)
)
/
CALCULATE(
DISTINCTCOUNT('Calendar'[DATE]);
DATESINPERIOD('Calendar'[DATE];LASTDATE('Calendar'[DATE]);12;MONTH
))
All my values that i have in my SUM column looks like this,
And my Rolling AVG abowe calculates to this,
After some error searching i find that this piece of code,
DISTINCTCOUNT('Calendar'[DATE]);
DATESINPERIOD('Calendar'[DATE];LASTDATE('Calendar'[DATE]);12;MONTH
)
Gives me a Distinct Count value of 356. And when build my report to look on Days. My Rolling Average does compute correctly.
BUT, this is not what i want since i want this DAX to return 12 and i cant figure out why is doesnt?
