Tableau allows you to add context and interactivity to your data using actions. Link to web pages, files, and other Tableau worksheets directly from your analytical results. Use the data in one view to filter data in another as you create guided analytical stories. Finally, call attention to specific results using highlighting.
For example, in a dashboard showing home sales by neighborhood you could use actions to help you quickly see relevant information for a selected neighborhood. Select a neighborhood in one view which then highlights the related houses in a map view, filters a list of the houses sold, and opens a web page showing census data for the neighborhood.
Note: Actions behave differently in workbooks that use cube data sources. Cube data sources do not accept actions from relational or other cube data sources. For example, suppose you have a workbook that contains a view that uses a MySQL data source, a second view that uses a cube data source A, and a third view that uses a cube data source B. Actions in a view that use the MySQL data source will not affect the views that use the cube data sources. However, actions in the view that use the cube A data source can affect the view that uses the MySQL data source. The view that uses the cube B data source will not be affected in this case.
There are three kinds of actions in Tableau: Filter, Highlight, and URL actions.
