Web
ECharts renders to canvas by default, while uPlot handles dense series with tens of thousands of points. Marks and axes stay on canvas; legends remain real, selectable HTML.
One chart API. Native everywhere.
High-performance, natively rendered graphs for web, iOS, and Android, designed for developers and coding agents.
Get started
yarn add @hzblj/zyplotiOS
SwiftUI and Swift Charts, exposed through an Expo module. Native rendering, native gestures, zero WebViews.
Android
A single Jetpack Compose Canvas renders marks, axes, and tooltips in one native view — without building a deep tree of components.
Examples
The same chart, in a whole screen
Five studies from the example app, on all three platforms.
Stocks
A quote screen that follows your finger
A headline price that tracks the scrub, a smoothed intraday line that stops where the session does, a range selector and a candlestick toggle — with native tabs and headers around all of it.

Crypto
A price trace with no axes at all
Price history that runs off both edges of the window, a dotted fill closed against the latest reading, the day's extremes underneath, and a scrub that lights the line up to the finger.

Tokens
A screen where nothing cuts
A resting wave that morphs into the window rather than a skeleton that is swapped for it, a step back that takes a beat when a finger lands, and a lit trail that holds until the rest of the trace has come back up.

Fitness
A bar chart wearing its own scale
Two gridlines and no more, the daily counts written inside the plot against its trailing edge rather than in a gutter beside it, and a two-finger span that totals the days it covers.

Markets
Chrome laid on the plot, not around it
A grid, a row of dates and a volume tape all placed off marks the chart measured and nobody drew — and a held span painted in its own direction by whoever is drawing the line.
