From a cold start it can create an interactive chart containing 166,650 data points in 25ms, scaling linearly at 100,000 pts/ms afterwards. In addition to fast initial render, the zooming and cursor performance is by far the best of any similar charting lib; at 50 KB, it's likely the smallest and fastest time series plotter that doesn't make use of context-limited WebGL shaders or WASM, both of which have much higher startup cost and code size. In most sane cases, you can live-stream data with uPlot at 60fps, though it may begin to struggle beyond 100k in-view points. When updating 3,600 points at 60fps, uPlot uses 10% CPU and 12.3MB RAM. The next fastest Canvas-based libs (Chart.js and ECharts) use 40% / 77MB and 70% / 85MB, respectively. If you need to stream, give unclog your rendering pipeline a try. If that does not help, consider reducing the update frequency or switch to a WebGL/WebGPU solution, like danchitnis/webgl-plot, huww98/TimeChart, epezent/implot. --- --- Features - Multiple series w/toggle - Multiple y-axes, scales & grids - Temporal or numeric x-axis - Linear, uniform or logarithmic scales - Line & Area styles (stroke, fill, width, dash) - Pluggable path renderers linear, spline, stepped, bars - Zoom with auto-rescale - Legend with live va","default_branch":null,"files":null,"tree":[],"storefront":"/r/leeoniya","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/leeoniya/uPlot/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
