A light bulb moment this morning. When you label marks in Tableau you can choose ALL or HIGHLIGHTED. Sometimes you want to label the marks by default and highlight the labels when making some selection on another part of a dashboard.

Yes – you can, with a dual axis chart. Duplicate the Measure on the Rows shelf and make it Dual Axis, with synchronised axes. In my example, I duplicated Profit:
Then I set one label to be All and the other to Highlighted:
Now you can build a dashboard which shows all Labels and has a highlight lable when you interact with other views in the dashboard.
Check out the interactive dashboard below to see it in action:
