5. You have sales data for 4 products over 3 months. You want to compare each product's sales side by side for each month. Which chart type and setup is best?

hard

A. Use a clustered column chart with products as series and months as categories

B. Use a stacked column chart to show total sales per month

C. Use a pie chart for each month separately

D. Use a line chart with months as series and products as categories

Solution

1. Step 1: Understand the comparison goal

   You want to compare products side by side for each month, not just totals.

2. Step 2: Choose chart type that shows side-by-side comparisons

   Clustered column charts display multiple series side by side per category, perfect for this.

3. Step 3: Check other options for fit

   Stacked columns show totals, pie charts don't compare multiple groups well, and line charts are less clear for side-by-side product comparison.

4. Final Answer:

   Use a clustered column chart with products as series and months as categories -> Option A

5. Quick Check:

   Side-by-side comparison = Clustered column chart [OK]

Hint: Clustered columns show side-by-side groups clearly [OK]

Common Mistakes:

• Using stacked columns which hide individual product values
• Choosing pie charts that can't compare multiple groups
• Using line charts that confuse category and series roles
