Tableau Parameter

A user-controlled workbook variable (number, date, string or list) that can be referenced in calculations, filters, reference lines and bins.

Definition

Parameters are global to the workbook and don't filter data by themselves until used in a calculation or filter. Parameter actions let users set values by clicking marks, and values can refresh dynamically on workbook open.

Exam tip

A parameter does nothing until referenced; letting users pick a measure to display = parameter + CASE calculation.
