This is one of 365 concepts on the Salesforce Tableau Data Analyst exam.

Next conceptParameter action aggregation for multiple selected marks

Explainer

A parameter action lets a viewer change a parameter's value by hovering over, clicking, or right-clicking marks in a viz, instead of using a parameter control. The parameter must also be used in the view, for example in a reference line or a calculated field, so changing its value changes what the user sees. This turns fixed reference lines and calculations into views that update as the user explores.
Core information
  • A parameter action changes a parameter's value when a user interacts directly with the viz, such as by clicking or selecting a mark. You can use it with reference lines, calculations, filters, and SQL queries. You can create it in Tableau Desktop, Tableau Cloud, and Tableau Server.
More details and nuances
  • If Aggregation is set to None and a user selects multiple marks with different values for the source field, the action does not run. To let users select multiple marks, you must choose an aggregation.
