Issue

When hovering over a mark in a view, the tooltip shows asterisks (*) for corresponding fields.

Environment

Tableau Desktop

Resolution

Option 1

Add the dimensions of the field you want to display to Detail.

Option 2

Use the dimensions elsewhere in the view to ensure that the marks are at the same level of detail.

Option 3

The following instructions can be reviewed in the attached workbook located on the right side of this page.

  1. Create a string list with a calculated field using the PREVIOUS_VALUE function.
  2. Add this field to the tooltip.

Cause

Dimensions are added to the tooltip using the ATTR aggregation. The asterisk is actually a visual indicator of a special type of Null value that occurs when there are multiple members that apply to the mark.

Additional Information

When using data blending, asterisks are typically displayed when there are more than one matching member in the secondary dimension for each mark.
