Scope of impact

Impact was specific to any user attempting to view data on a Cartesian chart pinned to the Power BI dashboard with standard light theme or dark theme enabled.

Root cause

A recent Power BI service update introduced a code regression that caused dashboard theme settings to incorrectly override the visual formatting of some pinned Cartesian charts, resulting in incorrect chart rendering.

Next steps:
- We’re reviewing our update procedures to help identify similar visual-rendering issues before deployment and prevent this problem from happening again.

This is the final update for the event.

Final status

We've determined that a recent Power BI update introduced a code regression that caused dashboard theme settings to incorrectly override the visual formatting of some pinned Cartesian charts, resulting in incorrect chart rendering. We’ve completed deployment of the fix and confirmed that the affected functionality has been restored and impact is no longer occurring.

To see whether your own tenant is affected, check Service health in the Microsoft 365 admin center. Only a backup outside Microsoft protects against data loss, and only a tested break-glass account against locked-out admins. We set up both in fixed-scope sprints.
