Measure Not Working on Line Chart Y-Axis Maximum

[Cabbage_Baby]

Hi Power BI Experts, I could use some help with a DAX and visual interaction issue:

I'm trying to create a dynamic Y-axis maximum for a line chart that responds to different levels of date granularity. Here's the measure I created:

The intention is to return a different maximum value based on the current date level selected via bookmark navigation (week, month, or year).

When I use this measure in a matrix visual, it works perfectly—returning the expected values when switching between date levels using the bookmark navigator.

However, when I try to apply this same measure to the Y-axis Maximum range via Conditional Formatting on a line chart, it doesn’t respond at all. The value remains static, regardless of which date granularity is selected.

Has anyone encountered this before? Is there a limitation with Conditional Formatting on axis properties in charts?

Hi @Cabbage_Baby ,

I recommend using a field parameter for selection of Week/Month/Year rather than bookmarks.

You can then retrieve the selected field parameter within the Max Y-Axis measures.

The problem with the bookmark method is that, at the "visual level" where the Max Y-Axis measure is evaluated, ISINSCOPE ( ... ) will always return false because there is no "hierarchy of levels" in that context. The hierarchy levels only exist for measures that are grouped by the axis fields, which is why the measure works in the matrix visual.

As an example, I created a field parameter called Date Parameterand edited the calculated table expression slightly:

Date Parameter = 
{
    ( "Week", NAMEOF ( Calendar_Lookup[Start of Week] ), 0 ),
    ( "Month", NAMEOF ( Calendar_Lookup[Start of Month] ), 1 ),
    ( "Year", NAMEOF ( Calendar_Lookup[Start of Year] ), 2 )
}

Then updated Max Y-Axis to:

Max Y-Axis = 
VAR SelectedDateParameter =
    IF (
        COUNTROWS ( 'Date Parameter' ) = 1,
        SELECTCOLUMNS ( 'Date Parameter', 'Date Parameter'[Date Parameter] )
    )
RETURN
    SWITCH (
        SelectedDateParameter,
        "Week", 10,
        "Month", 20,
        "Year", 30
    )

Note that we cannot directly write SELECTEDVALUE ( 'Date Parameter'[Date Parameter] )

(see here).

Finally, replaced the bookmark navigator with a slicer on 'Date Parameter'[Date Parameter].

I also recommend disabling Auto date/time.

PBIX attached.
