Normalized stacked area chart
Show how category shares change over time while normalizing every period to 100 percent. Create a private, publication-ready normalized stacked area chart directly in your browser without transmitting sensitive rows off-device. Data is processed locally on your hardware with zero server uploads, enabling instant export to SVG, PNG, and Excel data.
Edit the data, then export.
Everything runs in your browser. Your data is not uploaded.
Data
Paste tab-separated data from Excel or edit the cells directly.
Paste or import table data
Paste a header row, or choose a local CSV/TSV file. Files are read in this browser and capped at 500 rows.

SVG, PNG, and Excel exports are generated locally in this browser. PowerPoint export is temporarily unavailable while its dependency path is reviewed for a high-severity image parser advisory.
Temporal Dynamics & Trend Analysis
A normalized (or 100%) stacked area chart displays multiple time series stacked on top of one another, with each period’s total mathematically scaled to equal 100%. This removes absolute volume fluctuations to emphasize the relative percentage share of each category as it evolves over time. Trendalyzer processes and renders all data locally on your machine, guaranteeing that your sensitive datasets are never uploaded to external servers.
Time-Series Layout & Column Schema
Format input columns for normalized stacked area chart with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.
Sample Time Series Matrix
| Date | Mobile | Desktop | Tablet |
Design Rules for Longitudinal Data
- Ensure sufficient visual distinction for normalized stacked area chart marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for normalized stacked area chart elements.
- Double-check scale boundaries and zero-anchors before exporting normalized stacked area chart presentation artwork.
- Data shape
- Time period plus one numeric column per component
- Exports
- SVG, PNG, and Excel data; PowerPoint export is temporarily unavailable pending dependency review.
How it works
You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.
Frequently asked questions
When should I use normalized stacked area over standard stacked area?
