How does a Highlight Action work in Tableau?

In Tableau, what happens when you use a Highlight Action on a dashboard?

A It removes all marks except the selected ones from the view.

B It filters the data to show only the selected marks.

C It changes the color of selected marks to emphasize them while keeping others visible.

D It exports the selected data to a new worksheet automatically.

💡 Hint

Think about what 'highlight' means visually on a dashboard.

A Highlight Action changes the color or style of selected marks to make them stand out, but it does not filter or remove other data points.

Result of Highlight Action on Color Encoding

Suppose you have a Tableau dashboard with a Highlight Action set on a category field. What is the expected visual output when you select a category?

A Only the selected category's marks remain colored; all others turn gray.

B All marks change to the same color regardless of category.

C The selected category's marks become larger but keep their original color.

D The selected category's marks disappear from the view.

💡 Hint

Highlight Actions usually change color intensity or brightness.

When a category is selected, Highlight Actions dim other categories by turning them gray and keep the selected category colored to emphasize it.

Designing a Dashboard with Highlight Actions

You want to create a dashboard where selecting a bar in a sales chart highlights related customer segments in another chart without filtering them out. Which Tableau feature should you use?

A Use a Filter Action between the charts.

B Use a Highlight Action between the charts.

C Use a URL Action to link the charts.

D Use a Parameter Action to change the data source.

💡 Hint

Think about keeping all data visible but emphasizing related parts.

Highlight Actions emphasize related data points across charts without filtering out any data, perfect for this scenario.

🔧 Formula Fix

Why is the Highlight Action not working as expected?

You set up a Highlight Action on a dashboard, but when you select marks, nothing changes visually. What is the most likely cause?

A The data source is not connected to the workbook.

B The Highlight Action is set to run on hover instead of select.

C The dashboard has too many sheets for Highlight Actions to work.

D The source and target sheets do not share any common fields.

💡 Hint

Highlight Actions require a link between sheets.

Highlight Actions need common fields between source and target sheets to know which marks to highlight. Without shared fields, no highlight occurs.

Combining Highlight Actions with Filters for Advanced Interaction

You want a dashboard where selecting a region highlights related sales categories in one chart and filters the product list in another chart simultaneously. How should you configure the actions?

A Create a Highlight Action between region and sales categories, and a Filter Action between region and product list.

B Create two Highlight Actions: one for sales categories and one for product list.

C Create two Filter Actions: one for sales categories and one for product list.

D Create a Parameter Action to control both sales categories and product list.

💡 Hint

Think about when to highlight vs when to filter data.

Highlight Actions emphasize related data without hiding it, while Filter Actions reduce data shown. Combining both allows highlighting sales categories and filtering product list as required.
