Tableau Desktop Specialist — Question 9

You plan to create a visualization that has a dual axis chart. The dual axis chart will contain a shape chart and a line chart. Both charts will use the same measure named Population on the axis.
You need to configure the shapes to be much larger than the line.
What should you do?

Answer options

• A. Duplicate Population Drag the duplicate to the second Marks card and configure the size of the marks independently
• B. For the second axis, select Shape on the Marks card. From Select Shape Palette, select Custom, and then select Reset
• C. Create a custom shape that is larger than the default shape and add the shape to the Shapes folder in My Repository.
• D. Change Population to a discrete dimension.

Correct answer: A

Explanation

The correct answer is A because duplicating the Population measure and using it on the second Marks card allows for independent adjustments to the size of the marks. Option B does not address the size difference needed, C involves creating a new shape but does not help with size configuration on the axes, and D changes the nature of the data rather than the visualization itself.
