I have a table with 500 rows and one of the columns contains a few different values. I want to return a measure that counts the total number of three of the values.
So for example, in the pic below, I want to calculate the number of times Ages 11, 12 and 13 appears in the table - which is 7 times.
What is the DAX language for this?
Thank you

The 'IN' function will do this pretty cleanly. It will let you build a filter that limits your table to the rows whose values match the ones in a list that you supply. Then just count them up.
CountSpecificAges = CALCULATE(
COUNT (Table1[Age])
, Table1[Age] IN {11, 12, 13}
)

I would like to count in Power BI the total counts when a value comes out in 3 consecutive order. Highly appreciated the support.
If I may denote your columns as "tme" and "val" and the table as "tbl": a two-step approach with a calculated column would look as follows:
First, we evaluate the time-difference as a calculated column in every row to the next-largest zero with time before the time of the respective row (see "EARLIER"). We further take the modulus with respect to 3, so that we expose all entries, which are 3, 6, 9 elements greater than the next-smaller zero.
__DiffToLargestZeroBeforeMod3 = MOD(tbl[tme] - CALCULATE(
MAX(tbl[tme]),
FILTER(tbl, tbl[val] = 0),
tbl[tme] < EARLIER(tbl[tme])
), 3)
Next, we define a measure, which counts all '1' entries that have 3-modulo 0
_CntTriplets = CALCULATE(
COUNT(tbl[val]),
tbl[__DiffToLargestZeroBeforeMod3] = 0,
tbl[val] = 1
)
Hope this does the job for you! Note, that this also works if the column were to start with three 1's, as the result from the MAX operator would be None and, e.g. 3-None = 3 for DAX. Also note, that the calculated column is probably not the most compute-efficient approach ;)
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 work with a single table (called sTradeSim) that I have created in PowerQuery. It has 3 columns (Fund1, Fund2, Fund3), each having values from -10 to 10, with an increment of 1.
I also have three separate slicers, each created using an option "Greater than or equal to". Each slicer is having a field assigned to it - Slicer 1 = Fund1, Slicer 2 = Fund2, Slicer 3 = Fund3. Below is a screenshot of Slicer 1.
Right next to these three slicers is a table with three rows. For each row, I would like to retrieve the value of the respective slicers. So the desired result would look like:
Row No 1 = -10.00 (the value of Slicer 1),
Row No 2 = -2.00 (the value of Slicer 2),
Row No 3 = 3.00 (the value of Slicer 3).
Unfortunately, DAX formula that I have developed is always returning 3.00 (the value of the third slicer).
I have tried to find a solution on the forum and combine my SWITCH formula with ALL, ALLEXCEPT, SELECTEDVALUE etc., but it seems like I'm missing something very basic.
mHV_Trades =
SWITCH(
MAX(FundTable[FundsRanked]),
1, MIN(sTradeSim[Fund1]),
2, MIN(sTradeSim[Fund2]),
3, MIN(sTradeSim[Fund3])
)
What you are trying to do doesn't work, because essentially when you place 1 filter on any column on the table, it will filter all the rows that have that value. So, when you apply a filter fund1 = -10 it will also filter the values for fund 2 and fund 3.
You have 2 options:
Create independent tables each with values from -10 to 10
Create a table with all the combinations of -10 to 10 values for every fund.
For your example with 3 funds this works quite nicely (the table has about 10k records), all the combinations of -10 to 10 (21) to the power of 3, the problem with this solution is that depending on the number of funds you have you will run out of space quite quickly.
Problem
I'm trying to calculate and display the maximum value of all selected rows alongside their actual values in a table in Power BI. When I try to do this with the measure MaxSelectedSales = MAXX(ALLSELECTED(FactSales), FactSales[Value]), the maximum value ends up being repeated, like this:
If I add additional dimensions to the output, even more rows appear.
What I want to see is just the selected rows in the fact table, without the blank values. (i.e., only four rows would be displayed for SaleId 1 through 4).
Does anyone know how I can achieve my goal with the data model shown below?
Details
I've configured the following model.
The DimMarket and DimSubMarket tables have two rows each, you can see their names above. The FactSales table looks like this:
SaleId
MarketId
SubMarketId
Value
IsCurrent
1
1
1
100
true
2
2
1
50
true
3
1
2
60
true
4
2
2
140
true
5
1
1
30
false
6
2
2
20
false
7
1
1
90
false
8
2
2
200
false
In the table output, I've filtered FactSales to only include rows where IsCurrent = true by setting a visual level filter.
Your max value (the measure) is a scalar value (a single value only). If you put a scalar value in a table with the other records, the value just get repeated. In general mixing scalar values and records (tables) does not really bring any benefit.
Measures like yours can be better displayed in a KPI or Multi KPI visual (normally with the year, that you get the max value per year).
If you just want to display the max value of selected rows (for example a filter in your table), use this measure:
Max Value = MAX(FactSales[Value])
This way all filter which are applied are considered in the measures calculation.
Here is a sample:
I've found a solution to my problem, but I'm slightly concerned with query performance. Although, on my current dataset, things seem to perform fairly well.
MaxSelectedSales =
MAXX(
FILTER(
SELECTCOLUMNS(
ALLSELECTED(FactSales),
"id", FactSales[SaleId],
"max", MAXX(ALLSELECTED(FactSales), FactSales[Value])
),
[id] = MAX(FactSales[SaleId])
),
[max]
)
If I understand this correctly, for every row in the output, this measure will calculate the maximum value across all selected FactSales rows, set it to a column named max and then filter the table so that only the current FactSales[SaleId] is selected. The performance hit comes from the fact that MAX needs to be executed for every row in the output and a full table scan would be done when that occurs.

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' ) )
