uPlot is a small (~50 KB) and fast Canvas 2D-based JavaScript charting library for time series, lines, areas, OHLC, and bar charts. It renders hundreds of thousands of points in milliseconds with best-in-class zoom and cursor performance, and supports live data streaming at 60fps.

Use cases

• plot large time series datasets in the browser
• render financial OHLC candlestick charts
• stream live sensor data to a chart at 60fps
• add lightweight charts to a dashboard without heavy dependencies
• visualize millions of data points with fast zoom and pan
• sync cursors across multiple charts

When to choose

• you need the smallest and fastest time series charting library
• you're plotting very large datasets (100k+ points) where Chart.js or ECharts are too slow
• you want low CPU/memory usage for live streaming updates
• bundle size is a priority

When to avoid

• you need WebGL-level performance beyond ~100k in-view streaming points
• you need many chart types like pie, donut, or heatmaps
• you want a batteries-included charting library with extensive built-in styling and theming
• you need 3D or geographic plotting
