Quick summary
Changing legend text in Power BI requires renaming a field in the Data pane rather than through the visual formatting options. Once renamed, the updated label appears everywhere that field is used across your report, unless it has been overridden elsewhere.
Steps
- Go to the Data pane in Power BI.
- Click the three-dot menu next to the table that contains your legend field.
- From the menu, select Expand all to reveal all fields within the table.
- Select the target field, then click the three-dot menu next to that field.
- Select Rename from the field options menu.
- Enter your custom legend label in the text field.
- Confirm the change — the legend text updates everywhere the field is used unless it has been overridden elsewhere.
