Microsoft Power BI Data Analyst — Question 124

You need to use Power BI to create a visual that will allow users to compare the sales performance of five sales regions for the current month.

Which visual should you use?

Answer options

• A. a line chart
• B. a stacked bar chart
• C. a 100% stacked bar chart
• D. a waterfall chart

Correct answer: B

Explanation

A stacked bar chart allows for the comparison of total sales across multiple categories, in this case, the five sales regions, making it easier to visualize their performance relative to each other. The line chart is better suited for trends over time, while the 100% stacked bar chart displays proportions rather than absolute values, and the waterfall chart is used to show cumulative effects of sequentially introduced positive or negative values.
