Reference Line in Power BI Line Graph Displays Incorrect Format

[SmilikaL]

I have a Line Graph in Power BI that updates based on the selected metric. When I select Metric 16407, the US Pctl value (62.21%) is correctly reflected in the reference line of the graph.

However, when I select a metric that does not have "My R4Q" values but has a US Pctl value, such as Metric 16074 (98.83%), the reference line displays an incorrectly formatted value (e.g., a decimal instead of a percentage). When I add the measure used for the reference line to a table, it displays in the correct format. Similarly, if I use the measure on the Y-axis instead of as a reference line, it also appears in the correct format.

What could be causing this formatting issue? How can I ensure the reference line always displays the correct percentage format regardless of whether "My R4Q" has a value? Any insights or solutions would be greatly appreciated!

Hi @SmilikaL 

This is a known formatting issue with constant/reference lines in Power BI. Even if your X-axis is a date, Power BI sometimes shows the constant line label in number format (e.g. 45242 instead of 10/07/2024).

Quick workaround: manually type the label instead of using dynamic formatting. Or you can use a line chart with a measure-based line if you need full formatting control.

Can you share the measure used to generate the reference line
