When to Use Pie Charts
Pie charts work best when:
- You have 3-7 categories (more becomes hard to read)
- You want to show parts of a whole (percentages that sum to 100%)
- Categories are mutually exclusive
- The differences between slices are significant
Consider a bar chart instead if you have many categories, need precise comparisons, or your data doesn't represent parts of a whole.
Tips for Better Pie Charts
- Order slices from largest to smallest for easier reading
- Use contrasting colors that are distinguishable
- Limit to 5-7 slices maximum; group small items into "Other"
- Always include labels or a legend
- Consider a donut chart if you want to display a total in the center
