Tableau Desktop Certified Professional — Question 92

What statement correctly describes a requirement to create a reference line in Tableau?

Answer options

• A. The reference line must be paired with a date field.
• B. One of the axis must contain a dimension.
• C. The reference line must be created on a continuous axis.
• D. One of the axis must contain an aggregated measure.

Correct answer: C

Explanation

The correct answer is C because reference lines in Tableau can only be placed on continuous axes, which allow for proper scaling and representation of data over a range. Options A, B, and D are incorrect as they do not reflect the necessary conditions for creating a reference line, which specifically requires a continuous axis.
