Add context and interactivity to your data using actions. Users interact together with your visualizations by selecting marks, or hovering, or clicking a menu, and therefore the actions you found out can respond with navigation and changes within the view.

For example, during a dashboard showing home sales by neighborhood, you’ll use actions to display relevant information for a specific neighborhood. Selecting an area in one view can trigger an action that highlights the related houses during a map view, filters an inventory of the homes sold, then opens an external website showing census data for the neighborhood.
Here’s how you employ the various sorts of actions:

Filter. Use the info from one view to filter data in another to assist guide analysis.

Highlight. signalize to marks of interest by coloring specific marks and dimming all others.

Go to URL. Create hyperlinks to external resources, like an internet page, file, or another Tableau worksheet.

Go to Sheet. Simplify navigation to other worksheets, dashboards, or stories.

Change Parameter. Let users change parameter values by directly interacting with marks on a viz.

Change Set Values. Let users change the values during a set by directly interacting with marks on a viz.
