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.

Install SciChart.js

npm install scichart

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();

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>

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

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

Include index.min.js in your webpage

<!-- Include specific version into index.html -->
<script src="https://cdn.jsdelivr.net/npm/scichart@4.0.0-beta.734/index.min.js" crossorigin="anonymous"></script>

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]
            })
        })
    );
}
