How to sync a bar chart with the first row of a filtered table (single-row selection)?

[rask]

Scenario:

I have a Power BI report with:

1. A table visual showing multiple rows of data.

2. A bar chart visual that should display details from the first row of the table.

Requirements:

• On login, the bar chart must show data from the top row of the table (sorted by default).

• Users can only select one row at a time in the table (to ensure the bar chart shows only one record).

Challenges:

• The table’s first row changes based on slicers, but the bar chart doesn’t auto-update.

• Preventing multi-row selection in the table visual.

Question:

How can I:

1. Auto-sync the bar chart with the first row of the filtered table?

2. Restrict row selection to one at a time?

Hi @rask ,
Thank you for the helpful insighs @DataNinja777 !
Yes. As @DataNinja777 mentioned ,Power BI doesn’t directly let you auto-sync a bar chart with the first row of a table, but you may work around this by using a ranking measure to filter and show only that first row. 

Hope the answer helps.If so,consider acceptng it as solution.

Thank you.

Hi @rask ,

Power BI doesn't support auto-syncing a visual like a bar chart with the first row of a table visual directly. However, you can achieve the effect using DAX by ranking the filtered dataset and forcing the bar chart to only show data from the top-ranked row. First, create a measure that ranks the rows according to your sorting logic. For example, if you're sorting by [Revenue] in descending order:

TopRank = 
RANKX(
    FILTER(ALLSELECTED('Sales'), NOT ISBLANK('Sales'[Revenue])),
    'Sales'[Revenue],
    ,
    DESC,
    DENSE
)

Next, create another measure to identify whether a row is the top-ranked:

IsTopRow = IF([TopRank] = 1, TRUE(), FALSE())

Apply this [IsTopRow] = TRUE() measure as a visual-level filter on your bar chart. This will make the bar chart always show data from the first row based on the current filters and slicers.

Power BI does not support enforcing single row selection in a table visual. If users manually select multiple rows, the visual context may break. One workaround is to replace the table with a slicer based on a unique identifier (e.g., 'Sales'[ID]) and set the slicer to single select mode. This ensures only one item can be selected at a time and the bar chart will reflect that record. However, this loses the tabular preview, so it's a trade-off between functionality and appearance.

Best regards,
