Tableau Desktop Certified Professional — Question 9

To best improve the display of a scatter plot that has overlapping shapes, you should adjust the _____________ of the marks.

Answer options

• A. mark size
• B. mark borders
• C. color opacity
• D. color palette

Correct answer: C

Explanation

Adjusting the color opacity of the marks allows for better visibility of overlapping shapes, as it makes the colors more transparent and reveals the shapes beneath. Changing mark size or borders may not resolve overlap effectively, while altering the color palette may not improve clarity in cases of overlap.
