What does a stacked column chart display?

• A. It shows related metrics or variables stacked on top of each other in a single column
• B. It compares two metrics side-by-side in separate columns
• C. It displays frequency of categorized data points within defined ranges
• D. It illustrates data changes over time in a line chart

Answer: (A)

A stacked column chart displays related metrics or variables stacked on top of each other in a single column for each category. This shows the total for that category and how each component contributes to it, making it easy to compare both the overall size and the composition across categories. For example, you might see total sales by region with domestic and international sales stacked in the same column to reveal both the total and the split. If you need to compare two metrics side by side in separate columns, you’d use a side-by-side column chart. A histogram shows frequency counts of data grouped into ranges, and a line chart shows how values change over time.
