You create a dual axis chart that shows sales and profit over time. What should you do to distinguish sales from profit? (Choose two.)

Question

Exhibit

Options

• AAdjust the time frame displayed.
• BChange the mark types of sales and profit.
• CAdjust the aggregations for sales and profit to be different.
• DChange the color of sales and profit.

• A
  4% (2)
• B
  93% (51)
• C
  4% (2)

Explanation

In a dual axis chart, changing mark types (e.g., making sales a bar and profit a line) gives each measure a visually distinct shape, while changing colors applies different hues so viewers can instantly differentiate the two measures - both are standard, non-destructive ways to add visual distinction.

Why the distractors are wrong:

• A (Adjust time frame): Changing the time range affects what data is shown, not how the two measures are distinguished from each other.
• C (Adjust aggregations): Using different aggregations (e.g., SUM vs. AVG) changes the values being compared, which distorts the analysis rather than aiding visual clarity.

Memory tip: Think "shape and color" - the two most fundamental visual encodings in chart design. If you need to tell two things apart on the same chart, you change how they look (mark type = shape, color = hue), not how the data is calculated or filtered.
