Quick Start with NPM and Webpack

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

1. Install SciChart.js

npm i scichart

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

// New syntax from v3.0.284! import { all, the, things } from "scichart"
import { SciChartSurface, NumericAxis, NumericAxis, FastLineRenderableSeries } from "scichart";

// Call useWasmFromCDN once before SciChart.js is initialised to load Wasm files from our CDN
// Alternative methods for serving wasm from webpack or offline are available on our website
SciChartSurface.useWasmFromCDN();

// Apply your licese key once before startup
SciChartSurface.setRuntimeLicenseKey("--YOUR_KEY_HERE--");

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
    sciChartSurface.xAxes.add(new NumericAxis(wasmContext));
    sciChartSurface.yAxes.add(new NumericAxis(wasmContext));

    // Create a line series with some data
    const dataSeries = new XyDataSeries(wasmContext, {
        xValues: [1, 2, 5, 8, 10],
        yValues: [3, 1, 7, 5, 8]
    });
    const renderableSeries = new FastLineRenderableSeries(wasmContext, {
        dataSeries,
        stroke: "steelblue"
    });
    sciChartSurface.renderableSeries.add(renderableSeries);
}

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

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

Quick Start with Browser Bundle (Iife bundle)

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

1. Include index.min.js in your webpage

<!-- Always include latest scichart.js version -->
<script src="https://cdn.jsdelivr.net/npm/scichart/index.min.js" crossorigin="anonymous"></script>
<!-- or, choose specific version -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/index.min.js" crossorigin="anonymous"></script>
<!-- or, choosing latest version from 3.x -->
<script src="https://cdn.jsdelivr.net/npm/scichart@3/index.min.js" crossorigin="anonymous"></script>

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

// Imports when using Browser Bundle
const {
    SciChartSurface,
    SciChartDefaults,
    chartBuilder,
    SciChartJsNavyTheme,
    XyDataSeries,
    FastLineRenderableSeries,
    NumericAxis
} = SciChart;

// Option 1: Create chart with Builder API
async function initSciChartBuilderApi() {
    // Create a chart using the json builder api
    await chartBuilder.buildChart("chart0", {
        series: {
            type: "LineSeries",
            options: { stroke: "steelblue", strokeThickness: 5 },
            xyData: {
                xValues: [1, 2, 5, 8, 10],
                yValues: [3, 1, 7, 5, 8]
            }
        }
    });
}

// Option 2: Create chart with the programmatic API
async function initSciChartProgrammaticApi() {
    const { sciChartSurface, wasmContext } = await SciChartSurface.create("chart1", {
        theme: new SciChartJsNavyTheme()
    });

    sciChartSurface.xAxes.add(new NumericAxis(wasmContext));
    sciChartSurface.yAxes.add(new NumericAxis(wasmContext));

    sciChartSurface.renderableSeries.add(
        new FastLineRenderableSeries(wasmContext, {
            stroke: "#FF6600",
            strokeThickness: 3,
            dataSeries: new XyDataSeries(wasmContext, {
                xValues: [1, 2, 5, 8, 10],
                yValues: [3, 1, 7, 5, 8]
            })
        })
    );
}

// See deployment options for WebAssembly at https://www.scichart.com/documentation/js/current/Deploying%20Wasm%20or%20WebAssembly%20and%20Data%20Files%20with%20your%20app.html
// call useWasmFromCDN once before SciChart.js is initialised to load Wasm files from our CDN
SciChartSurface.useWasmFromCDN();
// Also, call & set runtime license key here once before scichart shown
SciChartSurface.setRuntimeLicenseKey("-- Your license key here --");

initSciChartBuilderApi();
initSciChartProgrammaticApi();
