How to show/hide the table matrix subtotals line based on multiple values being selected in a slicer

[wilsjay]

I have a basic report using a table matrix visual with several filters and slicers.  One of my slicers is a multi select.  When only one value is selected I want to show the totals line on the visual, when multiple values are selected in the slicer I want to hide the totals line.  What is the best way to implement this?  

I can create my own measure for each column with a DAX formula like the following:

ShowValueOrBlank =
VAR SelectedCount = COUNTROWS(VALUES('Table'[SalesID]))
RETURN
IF(
HASONEVALUE('Table'[SalesID]),
SUM('Table'[pr_hrs]),
BLANK()
)

Then check for HASONEVALUE to display.

Is there a better way to do this?  Then how to implement getting those new measures in the visual.  For instance, a Union?  Doesn't seem like the best way.

Hi @wilsjay
Thank you for reaching out to the Microsoft fabric community forum. Thank you @lbendlin, for your inputs on this issue.

After thoroughly reviewing the details you provided, I was able to reproduce the scenario, and it worked on my end. I have used it as sample data on my end and successfully implemented it.    

Power BI does not currently support conditionally showing/hiding subtotals in matrix visuals through a built-in feature. The only way to manipulate what’s visible is by controlling what data is displayed, which we can handle with DAX measures.

I am also including .pbix file for your better understanding, please have a look into it:

you cannot programmatically show/hide subtotals.  That can only be done in the UI.

Which is kinda weird as the rendering code would support it. If this is important to you please consider voting for an existing idea or raising a new one at https://ideas.fabric.microsoft.com
