Hi @Utilisateur_pb ,

Thank you for your update. I attempted to reproduce the issue using a similar dataset and configuration, and the constant line label is displaying correctly without showing "undefined." Thank you for your valuable inputs, @Anonymous .

Please ensure the following:

1. Valid Value Input:
• Confirm that the constant line value is entered manually or returned by a valid measure.
• Blank or invalid values can cause the "undefined" label.
2. Measure Validation (if applicable): Ensure your DAX measure doesn’t return BLANK () or null.
3. Data Label Settings: Under Data label, try toggling the Style option (e.g., from Both to Value).
4. Power BI Version: Check that you are using the latest version of Power BI Desktop.
5. Re-add Constant Line:  If all else fails, try removing and re-adding the constant line.

If you’ve already tried these steps and the issue continues, could you please share the exact steps or a snippet of your data model?  This will help me provide more precise guidance.

If my response solved your query, please mark it as the Accepted solution to help others find it easily.

And if my answer was helpful, I'd really appreciate a 'Kudos'.
