- Category A is the largest slice at 40.0%, taking up 144 degrees of the circle.
- Category D is the smallest active slice at 10.0% (36 degrees).
- The chart is divided into 4 slices. All percentages sum to 100% and all angles sum to 360 degrees.
- Pie charts work best when comparing fewer than 6 or 7 slices. Very small slices (under 5%) are hard to distinguish visually.
Next stepTo make a pie chart by hand, draw a circle with a protractor, mark the angles in order and label each segment with its name and percentage.
