Moving-average chart
Smooth short-term noise while retaining the underlying direction of a time series. Create a private, publication-ready moving-average 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 moving average chart displays raw time-series data overlaid with a line representing a rolling average (such as a 7-day or 30-day window). This visualization technique smooths out short-term fluctuations and random noise to reveal underlying, longer-term trends. By recalculating the average as the window moves forward in time, it clarifies the direction of the data without losing the historical context. All data processing and moving average calculations happen locally on your device, ensuring complete privacy with no server uploads.
Time-Series Layout & Column Schema
Format input columns for moving-average chart with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.

Design Rules for Longitudinal Data
- Ensure sufficient visual distinction for moving-average chart marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for moving-average chart elements.
- Double-check scale boundaries and zero-anchors before exporting moving-average chart presentation artwork.
- Data shape
- Ordered period and numeric value columns
- 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
How do I choose the moving average window size?
Use 7-day windows to remove weekly seasonality, 30-day windows for monthly smoothing, and 200-day windows for macroeconomic market trends.
