Matrix Visual

The issue you're encountering with Matrix Visual row headers bold formatting—where only the last inserted row responds correctly to the bold toggle and earlier rows do not—is a known behavior in Power BI.

Causes and Workarounds

• This is often due to how Power BI manages Row Subtotals and their formatting, which affects row headers globally.​

• The parent level row headers are intentionally always bold as part of the current design from the May 2024 update onwards.​

• You can try this workaround that has resolved similar issues:

  1. Enable Row Subtotals in the matrix visual format pane.

  2. In the Row Subtotals settings, locate the Values section and turn off the bold formatting.

  3. Turn on Apply to labels under these settings.

  4. Optionally, toggle off Row Subtotals after applying the formatting to keep your desired visual structure.

• This forces the bold setting to apply uniformly across all row headers, not just the last one.​

• Note that subtotal rows themselves remain bold, and complete removal of bold on all row headers may not be supported due to design behavior.​

Summary

• The behavior is partially by design after recent updates.

• Using row subtotal formatting with "Apply to labels" is the best workaround.

• Full control over bold row header formatting may require waiting for future Power BI updates or using custom visuals.

This approach should help you achieve consistent bold styling on all row headers in the Matrix Visual instead of just the last row.

Hi Jamey 

 It seems to work for me when I change the font. By default mine was coming through with the font 'wf_segoe_ui_semibold' which didn't change when I selected bold (as it is already semibold).

I hope this helps, please give kudos and mark as solved if it does!

Hi Jamey ,

Thanks a lot to all the wardy912 , MasonMA , tharunkumarRTK  and danextian  for jumping in with different approaches.

Jamey  did you get a chance to go through the suggestions shared (font family change, tabular layout, SVG column, and the note on expected behaviour)? Each has its own pros/cons depending on how much control you need.

Would be great to know if any of these worked in your case, or if you’re still seeing the same behaviour.

If you face any issues while trying them out, feel free to reach out here happy to help further.

Thanks,
Akhil.

Hi Jamey ,


Just checking in to see if you had a chance to try out the suggestions shared earlier (font family change, tabular layout, SVG column, etc.).

Did any one of above helps resolve the issue, or are you still seeing the same behavior? Happy to dive deeper if needed.

Thanks,
Akhil.

Hi Jamey ,

Just circling back were you able to test any of the earlier suggestions (font change, tabular layout, SVG column)?
Would be great to know if those adjustments made a difference or if the issue is still persisting so we can help troubleshoot further.

Thanks,
Akhil
