Tableau Creating and Formatting Visualizations 2 — Questions and Answers
Question 1: Which Tableau feature allows you to control the size of marks based on a measure or dimension?
- Color shelf
- Size shelf (Correct answer)
- Label shelf
- Detail shelf
Correct answer: Size shelf
The Size shelf encodes a field's values as the physical size of marks in the view.
Question 2: In Tableau, what happens when you place a continuous field on the Rows shelf?
- It creates a categorical header row
- It creates an axis along the row (Correct answer)
- It splits the view into separate panes
- It converts the field to discrete automatically
Correct answer: It creates an axis along the row
Continuous fields placed on Rows create a quantitative axis rather than discrete row headers.
Question 3: What is the purpose of the 'Fit' options (Fit Width, Fit Height, Entire View) in Tableau?
- To resize the data source
- To control how the visualization fills the view area (Correct answer)
- To adjust the window resolution
- To scale axis ranges proportionally
Correct answer: To control how the visualization fills the view area
Fit options control how the chart expands or contracts to fill the available view pane.
Question 4: Which mark type in Tableau is best suited for showing part-to-whole relationships?
- Bar
- Line
- Pie (Correct answer)

Pie charts are specifically designed to represent proportional or part-to-whole relationships between categories.
Question 5: When you right-click an axis in Tableau and select 'Edit Axis', which option sets a custom fixed range?
- Automatic
- Uniform axis range
- Fixed (Correct answer)
- Independent axis range

The 'Fixed' option in the Edit Axis dialog lets you specify exact start and end values for the axis.
Question 6: What does the 'Swap Rows and Columns' button do in Tableau?
- Transposes the data source
- Exchanges the fields on the Rows and Columns shelves (Correct answer)
- Rotates mark labels 90 degrees
- Changes horizontal bars to vertical bars only
Correct answer: Exchanges the fields on the Rows and Columns shelves
Swap Rows and Columns moves whatever fields are on Rows to Columns and vice versa, rotating the chart orientation.
Question 7: How do you add a reference line to a view in Tableau?
- Drag a measure to the Detail shelf
- Right-click the axis and choose 'Add Reference Line' (Correct answer)
- Use the Format > Reference Lines menu
