Frequently asked questions
How does it differ from a pie chart?
This renderer uses the area rose mode to vary sector sizes. A regular pie chart represents shares as slices of a fixed circle.
Which inputs are rejected?
Headers must be nonempty and unique, and numeric cells cannot be empty. Up to 1000 rows and 12 numeric series are supported; single-series and specialized charts have further column rules. Administrators may lower the row limit.
Does editing automatically update the chart?
Generate again after edits. Old results are cleared to avoid exporting a chart for stale input. Value labels are hidden above 40 rows; full data remains in the table and CSV.
