Hue Charts
One library for every chart.
See it

Colour: every series has 3:1 contrast with the background and stands apart from its neighbours, for every reader.
Your brand, kept readable
Your brand colour becomes series one, and every other series stays readable beside it.

Every peak, zoomed on the GPU.
No peak lost
One spike among a billion samples is drawn in its place at every zoom, from the whole record down to a few hundred samples.
One spike in a billion samples by range, its extremes built first in 2.96 s, traced at twelve zooms to 238 samples in Node 24.8, Intel Core i7-14700K, 28 October 2026.
Zooms on the GPU
A million points zoom at 124 frames a second on the GPU, and ten million at 140, on a desktop at 154 Hz.
Fast mode on the GPU, a million and ten million points held and zoomed for three seconds in Edge 156 on an Intel Core i7-14700K with an RTX 4060 Ti, on a screen read at 154 Hz, 28 October 2026.
Big data, small memory
A billion-sample chart takes about 260 MB, and a live stream's million-point window stays at 16 MB, tested over ten million values.
