SciChart.js is a High Performance JavaScript Chart library. Leveraging WebGL, WebGPU and WebAssembly to achieve incredible big-data and real-time performance. Fast and able to draw millions of datapoints in realtime, our charts will never cause your app to slow down again!

Why SciChart?

• Learn why we propose SciChart as the Best JavaScript Chart Library in 2024 for Big-Data, complex enterprise apps.
• Read performance test results showing SciChart beating Chart.js, HighCharts, Plotly by a wide margin in a JavaScript Chart Performance Comparison
• Learn the features and key differences of SciChart.js JS Charts library.
• Browse the demos of JavaScript Charts and JavaScript 3D Charts in our interactive React showcase.

SciChart has an extremely configurable and extensible API and is perfect for scientific, financial, medical, engineering and enterprise applications, apps with demanding performance requirements or complex and mission critical charting.

Releases

SciChart.js v6 is the first release supporting WebGPU which sagnificantly improves multichart scenarious like dashboards. Our userbase has demanding requirements from F1 to medical dashboards, IoT telemetry in industrial, aerospace and defense applications, and v6 answers them with:

• WebGPU rendering — a brand new renderer, selected automatically on Apple Silicon Macs, with WebGL used everywhere else.

• A tree-shakeable package — scichart now ships dual ES-module and CommonJS builds, so bundlers drop the parts of the library you don't use.

• One modular WebAssembly engine — 2D and 3D are now a single wasm module, and the 3D engine is fetched lazily, so 2D-only pages never pay for it.

• wasm64 (Memory64) binaries — optional builds that lift the 4GB memory ceiling for very large datasets.

• TableDataSeries — the renamed and extended XyNDataSeries, now with string-column support.

Upgrading to v6

Read the v5 to v6 Breaking Changes first. Most apps need two changes: the WebAssembly copy step is now a single _wasm directory copy (the separate scichart2d.wasm / scichart3d.wasm files are gone), and a SciChart3DSurface.configure() call should be deleted because SciChartSurface.configure() now configures both engines.

Quick Start with NPM and Webpack

Tutorial

See full npm + Webpack tutorial here

SciChart.js can be loaded as an ES6 module with Babel or TypeScript transpiler.

1. Install SciChart.js

npm install scichart

2. Create a simple chart by putting this into src/index.js file

import { SciChartSurface, NumericAxis } from "scichart";

async function initSciChart() {
    const { sciChartSurface, wasmContext } = await SciChartSurface.create("scichart-root");

    // Create an X,Y Axis and add to the chart
    const xAxis = new NumericAxis(wasmContext);
    const yAxis = new NumericAxis(wasmContext);

    sciChartSurface.xAxes.add(xAxis);
    sciChartSurface.yAxes.add(yAxis);
}

initSciChart();

3. Create src/index.html file

<html lang="en-us">
    <head>
        <meta charset="utf-8" />
        <meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
        <title>SciChart.js Tutorial 1</title>
        <script async type="text/javascript" src="bundle.js"></script>
    </head>
    <body>
        <h1>Hello SciChart.js world!</h1>
        <p>In this example we setup webpack, scichart and create a simple chart with one X and Y axis</p>

        <!-- the Div where the SciChartSurface will reside -->
        <div id="scichart-root" style="width: 800px; height: 600px;"></div>
    </body>
</html>

4. Serve the WebAssembly files. SciChart.js ships its WebAssembly binaries in node_modules/scichart/_wasm/. Copy that whole directory next to your bundle, e.g. with webpack:

new CopyPlugin({
    patterns: [{ from: "node_modules/scichart/_wasm/", to: "" }]
});

Or skip the copy step entirely and load them from our CDN by calling SciChartSurface.useWasmFromCDN() before you create a chart.

5. Run it npm start. As a result you will see a simple line chart.

Tree-shaking

v6 ships dual ES-module and CommonJS builds, so bundlers that honour the exports and sideEffects fields drop the parts of SciChart.js you never import - including the 3D engine, which is a separate WebAssembly module fetched only when you create a 3D chart.

Your bundler has to see ES-module syntax for this to work. TypeScript projects that emit CommonJS get the non-shakeable build, so set:

{
    "compilerOptions": {
        "module": "esnext",
        "moduleResolution": "bundler"
    }
}

Quick Start with Browser Bundle (Iife bundle)

Tutorial

See the full browser bundle tutorial here

If your environment does not include a bundler like Parcel or Webpack, you can still load SciChart.js using the browser bundle module from jsDelivr

1. Include index.min.js in your webpage

<!-- Include specific version into index.html -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/index.min.js" crossorigin="anonymous"></script>

2. Create scichart-example.js file with a simple chart

// Equivalent of imports when using index.min.js is to declare global variables like this
const { SciChartSurface, NumericAxis, FastLineRenderableSeries, XyDataSeries } = SciChart;

async function initSciChart() {
    // Create the SciChartSurface in the div 'scichart-root'
    const { sciChartSurface, wasmContext } = await SciChartSurface.create("scichart-root");

    // Create an X,Y Axis and add to the chart
    const xAxis = new NumericAxis(wasmContext);
    const yAxis = new NumericAxis(wasmContext);

    sciChartSurface.xAxes.add(xAxis);
    sciChartSurface.yAxes.add(yAxis);

    // Add a series
    sciChartSurface.renderableSeries.add(
        new FastLineRenderableSeries(wasmContext, {
            dataSeries: new XyDataSeries(wasmContext, {
                xValues: [0, 1, 2, 3, 4],
                yValues: [2, 1, 4, 3, 2]
            })
        })
    );
}
