Question 450
A user should switch a chart axis between Region, Brand and Channel without navigating to new visuals. What is the MOST appropriate Power BI design decision?
Explanation
Correct Answer
Field parameters allow user-driven switching of field assignments in supported visuals, supporting dynamic category axis selection.
Incorrect Answers
Fixed fields are simpler when dynamic user selection is unnecessary. It would address static chart field assignment, not dynamic category axis selection.
Measure field parameters let users select which measure appears in an eligible visual. It may suit interactive metric switching, not dynamic category axis selection.
Numeric what-if parameters provide scalar inputs, not field replacement. It is useful for adjustable analytic threshold, not for dynamic category axis selection.
