Graphs with the zoomslider and BLANK() measure is broken

[LaMatt]

Hi there,

As a standard graphs will go blank (show nothing) if blank() is returned in a measure, allowing developers to control wheter to show data in a visual or simply have it appear as empty.  However, when the zoomslider is enabled, the graphs no longer return nothing if blank() is returned in the measure, rather the visual will show data from the previous state.

As an example, assume you have a table with a list of products and KPIs, as well as two graphs of different types. The two visuals have measures similar to the one above with a condition similar to the one below, only difference being that the in one BLANK() is returned when true, and in the other BLANK() is returned when false.

IF( HASONEFILTER( Product[Name] ), [Measure], BLANK() )

When a user clicks on a product in the table with product names and KPIs the condition will become true in one measure for one visual, and false for another measure in the other visual, thus always returning BLANK() in one visual, and thereby only showing data in one visual at a time.

This little UX trick has worked like a charm for years in both Desktop and Service, however, today reports using this method no longer displays correctly in Power BI Service. Visuals with the zoomslider enabled that are meant to return blank (= nothing) instead show the values from the previous state.

I tested and confirmed that everything works as intended as long as the zoomslider is disabled. As mentioned before, having the zoomslider enabled didn't present this issue until today.

Some help on this issue would be much appreciated.

Thank you!

Hi @LaMatt ,

Thank you for your feedback, we need more details in order to better investigate your issue.
1. Does your issue only occur in Power BI Service, and it still works in Power BI Desktop?
2. Your current version of Power BI Service.
3. What browser are you using and does the problem persist if you clear your browser cache or change browsers?

Best regards.

@v-xiaoyan-msft any update on this?

[LaMatt]

@v-xiaoyan-msft after my deskop version was upgraded to 2.138.782.0 (Nov Release) the issues now also exists in the Desktop version.

Has this issue even been confirmed by the team yet? I am sure other users are seeing the same issue but might not be able to pinpoint the cause.

Attaching some screenshots to prove that this is a real issue.

The first two screenshots illustrate how it should work, while the third shows how it looks in actuality after the recent Power BI update(s).
