About this example
This pie chart classifies 40 illustrative articles into four types. Original research accounts for 24/40, or 60.0%; reviews for 9/40, or 22.5%; methods papers for 4/40, or 10.0%; and commentaries for 3/40, or 7.5%.
Open the example and replace the category names and counts. Assign each article to one category using a consistent rule, then check that the displayed total matches your included set. These illustrative counts are not results from a published literature review.
Slice size describes composition, not publication timing or article quality. If your question concerns annual counts, use the publications line graph. The research-sites pie example shows how independently rounded labels can sum to 100.1%.
