Dynamic categories (category changed/recalculated based on slicer choices)

CJonsson — Wed, 31 Jan 2024 14:01:02 GMT

Hi!

We have a dataset with Z-scores for different indexes. What we want to do is create an average per country, and then split these averages into four different categories according to the below split.

This category should be dynamic, to reflect the average and subsequent category for only the selected indexes.

SWITCH (

TRUE(),

WeightedIndexISO >= 0.675, "1",

WeightedIndexISO >= -0.6745, "2",

WeightedIndexISO >= -1.349, "3",

WeightedIndexISO < -1.349, "4",

"ERROR"

Our isssue is that we are not able to make the category dynamic. It just shows one single bucket based on the average for all indexes and countries, no matter the selection in slicers.

For example. When having all indexes selected Mexico will have an average Z score of -0.50 and end up in bucket 2.

But when selecting only index OCI Criminal Markets the weighted Z score is -2.48 and it should end up in bucket 3. However this doesn't work, it still says bucket 2.

Does anyone know how to create a measure for the buckets that is updated accordingly when selecting specific indexes?

I have added a table with sample data as I cannot attach a file in this post.

Re: Dynamic categories (category changed/recalculated based on slicer choices)

To create dynamic categories based on slicer choices in Power BI, you need to use measures that respond to the current filter context. In your case, you want to categorize countries based on the average Z-score of selected indexes. You can achieve this using a DAX measure that calculates the average Z-score for the selected indexes and then assigns the category accordingly.

Here's a general approach to achieve this:

Calculate the Average Z-score for Selected Indexes: You need to create a measure that calculates the average Z-score for the selected indexes.
Assign Categories Dynamically: Use a SWITCH statement in another measure to assign categories dynamically based on the average Z-score.

Here's how you can implement these steps:

Step 1: Calculate the Average Z-score for Selected Indexes

AverageZScore =
VAR SelectedIndexes = VALUES('YourIndexColumn')
RETURN
AVERAGEX(
FILTER(
'YourTable',
'YourIndexColumn' IN SelectedIndexes
),
[Value]
)

Notes:

Replace 'YourIndexColumn' with the appropriate column containing index names.
Replace 'YourTable' with the name of your table.
Replace '[Value]' with the column name that contains the Z-scores.
Ensure that the slicer visuals are set up to filter the appropriate columns in your data model.

These measures should dynamically respond to slicer selections, recalculating the average Z-score and assigning categories accordingly. Make sure your visuals are configured to react to these measures appropriately.

Thank you! That worked and the category is dynamic now.

One follow-up question. I would like to have a table showing the different categories and how many countries place within each category (still dynamic based on which indexes I choose). However, when placing the DynamicCategory in a table it will just show one category - calculating the average for all countries combined.

Is it possible to group this by country?

Certainly! If you want to display the count of countries within each category dynamically based on the selected indexes, you can create another measure to count the distinct countries within each category. Here's how you can do it:

Step 1: Create a Measure to Count Countries by Category

Countries by Category =
COUNTROWS(
FILTER(
VALUES('YourTableName'[Country]),
[Dynamic Category] = SELECTEDVALUE('YourTableName'[Dynamic Category])
)
)

Step 2: Build the Table

Now, you can create a table visual with two columns:

Category: Drag the Dynamic Category measure to this column.
Country Count: Drag the Countries by Category measure to this column.

Ensure that the table visual is not applying any additional filters or slicers that might interfere with the dynamic calculation of the measures.

This table will dynamically display the count of countries within each category based on the selected indexes. It should update as you change the selections in your slicers or filters.

Adjust the column names and formatting as per your preferences. This setup allows for a dynamic display of country counts within each category.

I am not quite getting this to work.

I cannot select the DynamicCategory as SELECTEDVALUE. Don't know if that is because it is a measure?
