DAX
Dear PBI Family ,
It's just 2 months that I have started using power bi I as my daily work now
I am stuck in an issue please consider if you can answer to this question so that it helps me alot
I have a measure which calculates from different fields and gives me a value which can be filtered using date slicer.
Let's call this measure as test
Now my problem is I have to put values which I get from this test measure range wise into a table like for example the expected result is as below
Name <0.25 0.25-0.50 0.50-0.75 >0.75
A 1 2 66 23
B 12 22 6 28
C 12 22 6 28
Currently I have achieved it using a long way that is I am make four measures and every measures count rows by filtering the table according to the value for example
For <0.25 = Countrows(Filter(test<0.25))
I read somewhere regarding this evaluate dax
Which returns a table so I was thinking if is it possible to get my expected result using evaluate
Note - name colunmn in above expected result is a field from a table students where values are A,B and C
Please project some light on my question thank you

Sujit
Hi Sujit_Thakur ,
Do you want to count the number of Model or the number of Name?
We can create two measures and use the following ways to meet your requirement.
1. Create a Model column in data table.
Model = CALCULATE(MAX('index table'[Model]),FILTER('index table','index table'[Name]='data table'[Name]))2. Create a new table.
Table = CROSSJOIN(VALUES('index table'[Model]),{"<0.25","0.25-0.5","0.5-0.75",">0.75","Total"})3. If you want to count the number of Name, you can use the following measure.
Measure = var _025 = CALCULATE(COUNT('data table'[Name]),FILTER('data table',[Test]<0.25 && 'data table'[Model]=MAX('Table'[Model]))) var _025_05 = CALCULATE(COUNT('data table'[Name]),FILTER('data table',[Test]>=0.25&&[Test]<0.5 && 'data table'[Model]=MAX('Table'[Model]))) var _05_075 = CALCULATE(COUNT('data table'[Name]),FILTER('data table',[Test]>=0.5&&[Test]<0.75 && 'data table'[Model]=MAX('Table'[Model]))) var _075 = CALCULATE(COUNT('data table'[Name]),FILTER('data table',[Test]>=0.75&& 'data table'[Model]=MAX('Table'[Model]))) return SWITCH( TRUE(), MAX('Table'[Value]) = "<0.25",_025, MAX('Table'[Value]) = "0.25-0.5",_025_05, MAX('Table'[Value]) = "0.5-0.75",_05_075, MAX('Table'[Value]) = ">0.75",_075, MAX('Table'[Value]) = "Total",_025+_025_05+_05_075+_075)4. If you want to count the number of Model, you can use the following measure.
Measure 2 = var _025 = CALCULATE(DISTINCTCOUNT('data table'[Model]),FILTER('data table',[Test]<0.25 && 'data table'[Model]=MAX('Table'[Model]))) var _025_05 = CALCULATE(DISTINCTCOUNT('data table'[Model]),FILTER('data table',[Test]>=0.25&&[Test]<0.5 && 'data table'[Model]=MAX('Table'[Model]))) var _05_075 = CALCULATE(DISTINCTCOUNT('data table'[Model]),FILTER('data table',[Test]>=0.5&&[Test]<0.75 && 'data table'[Model]=MAX('Table'[Model]))) var _075 = CALCULATE(DISTINCTCOUNT('data table'[Model]),FILTER('data table',[Test]>=0.75&& 'data table'[Model]=MAX('Table'[Model]))) return SWITCH( TRUE(), MAX('Table'[Value]) = "<0.25",_025, MAX('Table'[Value]) = "0.25-0.5",_025_05, MAX('Table'[Value]) = "0.5-0.75",_05_075, MAX('Table'[Value]) = ">0.75",_075, MAX('Table'[Value]) = "Total",_025+_025_05+_05_075+_075)The SWITCH function means that when the current column is equal to a certain value, output the corresponding value.
For example, when Table[Value] = “<0.25”, then output the value conforming to <0.25.
If it doesn’t meet your requirement, could you please show the exact expected result based on the table that you have shared?

Hi Sujit_Thakur ,
What you can try is created a calculated column which defines your categories as <0.25 , 0.25-0.50 , 0.50-0.75, >0.75 based on your TEST measure.
Then try using this column in a matrix visual under COLUMN section along with your Name column under ROW section.
Thanks,
Pragati

Dear pragati , I appreciate your response
But if I created a calculated column my values will not change when I change date selection from my date slicer

Hi Sujit_Thakur ,
We create a sample. We can use a matrix table and a measure to meet your requirement.
1. Create a new table.
Table 2 = CROSSJOIN(VALUES('Table'[Name]),{"<0.25","0.25-0.5"})2. Then we can create a matrix table based on the new table, create a measure and put it in Values.
Measure 2 = SWITCH( TRUE(), MAX('Table 2'[Value]) = "<0.25",CALCULATE(COUNT('Table'[Name]),FILTER('Table',[Measure]<0.25 && 'Table'[Name]=MAX('Table 2'[Name]))), MAX('Table 2'[Value]) = "0.25-0.5",CALCULATE(COUNT('Table'[Name]),FILTER('Table',[Measure]>=0.25&&[Measure]<0.5 && 'Table'[Name]=MAX('Table 2'[Name]))))If it doesn’t meet your requirement, could you please provide a mockup sample based on fake data or describe the fields of each tables and the relations between tables simply?
It will be helpful if you can show us the exact expected result based on the tables.

Hi Sujit_Thakur
Add this table to your model. I have named this HP-OP-Bounds.
After that create two calculated columns(HP/OP and Bin) as shown below in your table. I have named this table 'HP-OP'.
The formulaes for calculated columns are shown below.
HP/OP = DIVIDE('HP-OP'[HP], 'HP-OP'[OP], 0) Bin = VAR X = 'HP-OP'[HP/OP] VAR Filtered = FILTER ( 'HP-OP-Bounds', VAR Y = 'HP-OP-Bounds'[Upper Bound] RETURN 'HP-OP-Bounds'[Lower Bound] <= X && IF ( ISBLANK ( y ), TRUE (), Y > X ) ) RETURN MAXX ( Filtered, 'HP-OP-Bounds'[Bin] )Now use matrix visual as shown below.
Hope this helps.
Appreciate with kudos.
Please mark it as solution if this resolves your problem.
Thanks

Dear friend Anonymous ,
Can I create this same using measure , as I want to later use date slicer , using calculated columns will not help me when I want HP/OP to be recalculated every time I change date range .
You seriously brought me much closer to ans , please answer how can I achieve by using HP/OP as a calculated measure , because as you can see I have date column too of which I will add date slicer .

No, EVALUATE is not avaialbe within PBI, at least not in this sense. The only place it could be used is to import data from SSAS, for example.
- Sujit_ThakurSolution Sage
Dear Arklur ,
Is there any way of getting an output as an table using DAX ?
I have dax studio installed on my system , I read somewhere that I can use evaluate using DAX studio
- Pragati11Super User
Hi Sujit_Thakur ,
EVALUATE is not available as a DAX function in POwer BI.
When you tallk about EVALUATE in DAX Studio tool, it just serves as a starting query variable to write a dax expresion within it for dax studio tool to execute it.
In DAX studio tool, a DAX expression is identified within EVALUATE clause. So, EVALUATE is just a clause used to write your dax expression in this tool. It's just an statement needed to execute a query within this tool.
You can read in detail here: https://dax.guide/st/evaluate/

Sujit_Thakur - Since you mentioned me I'll chime in. Unless I missed it, I don't have a good sense of your source data. I see the expected output. Can you post a sample of what your source data looks like or point me to where it is posted? Thanks.
- AnonymousNot applicable
Sujit_Thakur If the segments are fixed i.e. (<0.25 0.25-0.50 0.50-0.75 >0.75).
You can use the parameter table pattern.

Dear v-zhenbw-msft Greg_Deckler and all ,
following is pasted data sample for question , please note the measure" Test" is nothing but divide(HP,OP).
I hope after this sample data v-zhenbw-msft you can help me with your previously discussed technique

Hi Sujit_Thakur ,
We can create a measure to meet your requirement.
Before that we need to create a new table.
Table = CROSSJOIN(VALUES('Data'[Name]),{"<0.25","0.25-0.5","0.5-0.75",">0.75"})Then create a measure like this,
Measure = SWITCH( TRUE(), MAX('Table'[Value]) = "<0.25",CALCULATE(COUNT('Data'[Name]),FILTER('Data',[Test]<0.25 && 'Data'[Name]=MAX('Table'[Name]))), MAX('Table'[Value]) = "0.25-0.5",CALCULATE(COUNT('Data'[Name]),FILTER('Data',[Test]>=0.25&&[Test]<0.5 && 'Data'[Name]=MAX('Table'[Name]))), MAX('Table'[Value]) = "0.5-0.75",CALCULATE(COUNT('Data'[Name]),FILTER('Data',[Test]>=0.5&&[Test]<0.75 && 'Data'[Name]=MAX('Table'[Name]))), MAX('Table'[Value]) = ">0.75",CALCULATE(COUNT('Data'[Name]),FILTER('Data',[Test]>=0.75 && 'Data'[Name]=MAX('Table'[Name]))))If you have any questions, please kindly ask here and we will try to resolve it.

Sujit_Thakur How do you intend too use date slicer?
I guess the HP/OP formulae become SUM(HP)/SUM(OP) for a selected date range right?
- Sujit_ThakurSolution Sage
Yes Anonymous ,
its SUMX(Table,'Table'[HP]) / SUMX(Table,'Table'[OP])- Sujit_ThakurSolution Sage
Anonymous so that everytime i slice date range , HP / OP is recalculated and values in output table changes

Thanks v-zhenbw-msft
You have helped me a lot .
One last doubt ,
What if my data grown , does it will hamper the Visualization calculation speed ?
Like now I have only 5 names , what if tomorrow I get data for 5000 names then the crossjoin table would size almost 25000 rows ? I just wanted to ask will this hamper my models efficiency ? About how much space it will take ?
Please help
