You can create aliases (alternate names) for members in a dimension so that their labels appear differently in the view.
Aliases can be created for the members of discrete dimensions only. They cannot be created for continuous dimensions, dates, or measures.
Create an alias
In the Data pane, right-click a dimension and select Aliases.
Tip: If Aliases does not appear in the dialog, verify that you are not connected to a published data source and the field you are trying to alias is a discrete dimension.
In the Edit Aliases dialog box, under Value (Alias), select a member and enter a new name.
Tip: To reset the member names back to their original names, click Clear Aliases.
To save your changes:
- In Tableau Desktop, click OK.
- On Tableau Server or Tableau Online, click the X icon in the top-right corner of the dialog box.
When you add the field to the view, the alias names appear as labels in the view. For example,
When the Alias option is not available
Measures can't be re-aliased
Tableau does not permit re-aliasing measures as this would involve modifying data values themselves. If you have a field in your data that contains values such as 0 and 1 but actually encodes information such as no and yes, Tableau will interpret this as a continuous measure. You can convert it to a discrete dimension and then re-alias the values. For more information about discrete vs continuous and dimensions vs measures, see:
- Dimensions and Measures, Blue and Green
- Convert a Measure to a Dimension
- Convert Fields between Discrete and Continuous
Published data sources
Alternatively, the Alias option may be missing for a discrete dimension because you are connected to a published data source. When using a published data source, you cannot create or edit aliases. You can only change aliases on fields that you create in your workbook. If you didn’t publish the data source, you can duplicate the field (right click > Duplicate) and edit aliases for the duplicate field without restriction.
