Display cumulative rows in a table when clicking on a cumulative chart

PopoLolo — Tue, 07 Oct 2025 19:23:42 GMT

Hello,

I need help creating an interaction between a chart and a table in Power BI.

Context:

I have a stacked bar chart displaying monthly cumulative IDTs (for example: January = 2 IDTs, February = 5 cumulative IDTs since January, March = 8 cumulative IDTs since January, etc.)
Below it, I have a table listing IDT details with their information (Interface Reference, Phase, Owner Entity, etc.)
Both visuals are linked through a calendar date table DIM_Date which is connected to my fact table via the date field

Current issue: When I click on September in the chart, the table only displays IDTs from September (default Power BI behavior).

Desired result: I would like the table to display all IDTs from January to September (cumulative) when I click on September, and similarly for all other months.

What I've tried:

Modifying interactions between visuals (but it doesn't change the behavior)
Creating filter measures, but I get context errors

Question: How can I make the table display cumulative rows up to the selected month in the chart?

Thanks in advance for your help!

Hi PopoLolo,

You’re running into the default cross-highlight behavior: when you click September, the chart filters the model to only September, so the table can’t “see” January-August anymore. To get cumulative rows, you need to (1) stop the chart from filtering the table and (2) read the selected month from a disconnected date axis, then (3) apply your own “≤ selected month” logic to the table.

This is untested, but is how I would approach this. If you share a sample file with data I can make modifications to it for you to achieve the desired result.

Create a disconnected date axis (no relationships):

DateAxis =
ADDCOLUMNS (
    CALENDAR ( DATE(2025,1,1), DATE(2025,12,31) ),
    "YearMonth", FORMAT ( [Date], "YYYY-MM" )
)

Use that DateAxis on your stacked bar chart axis.
Turn off the chart > table interaction (Format pane > Edit interactions > set the table to “None”).
Add a measure the table can use to include rows up to the selected month:

Selected Max Date =
VAR selMax =
    MAX ( DateAxis[Date] )   -- comes from the disconnected axis
RETURN
IF ( ISBLANK ( selMax ), BLANK (), selMax )

Show Up To Selection? =
VAR sel = [Selected Max Date]
VAR rowDate = SELECTEDVALUE ( DIM_Date[Date] )
RETURN
IF (
    ISBLANK ( sel )
        || ( NOT ISBLANK ( rowDate ) && rowDate <= sel && YEAR ( rowDate ) = YEAR ( sel ) ),
    1, 0
)

Put Show Up To Selection? in the table’s Visual-level filters = 1.
Now when you click September in the chart, the table ignores the chart’s filter but still reads the selection and shows January–September rows.
