About this tool
Accumulate nonnegative series into area bands to show totals and composition over categories. Use ordered categories first, then nonnegative numeric components. Inspect the cumulative top boundary and each band thickness; input order determines category order. Data and charts are processed in your browser and can be exported as PNG, SVG or CSV. Examples are illustrative.
How to use
- Use ordered categories first, then nonnegative numeric components.
- Set the title, palette, background and value labels, then generate the chart.
- Inspect the cumulative top boundary and each band thickness; input order determines category order. Compare the data table before downloading the image or CSV.
Frequently asked questions
Why are negative values rejected?
This stacked area chart accepts nonnegative components to avoid mixing positive and negative areas. Use Diverging Bar Chart for signed comparisons.
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.
