JSCharting has all the features you need and many you don't yet know you want.

    Using CDN

    Visit code.jscharting.com for a list of available releases.

    <script src="https://code.jscharting.com/latest/jscharting.js"></script>


    The latest release can be downloaded here.

    Using npm

    See npm documentation to get started with npm.

    npm install --save jscharting
    Working with a local copy of JSCharting

    The npm package folder jscharting/dist/ includes all the necessary charting JavaScript files and resources such as icons, polyfills, and mapping data files. The chart loads these resources dynamically as needed. The content of this folder should be accessible through http, so when building, copy this folder to a destination in the output website.

    If the chart detects a script tag pointing to the main jscharting.js file, it will assume the rest of the resources are located in the same place and will load them from there.

    If the JSC namespace is imported from the jscharting.js file as a module, the chart will not know where resources are located and will load them from the CDN. If debug: true chart option is set, a warning message will note that the chart is using the CDN. In order to use local resources, point the chart baseUrl option to the location of the local copy of the jscharting/dist/ folder.

    To avoid setting the baseUrl property on every chart instance, it can be set as a global default like so:

    JSC.defaults({ baseUrl: './js/jsc/' });

    A wrapper module can be used to apply the baseUrl and any other default options that should be used globally such as debug, or styling options. All subsequent charts can import this wrapper instead of the chart itself to ensure the default options are always applied.

    import * as JSC from "jscharting";
    JSC.defaults({ baseUrl: './js/jsc/' });
    export default JSC;

    First Chart

    A target div element is required in the page for the chart to render in.

    <div id="chartDiv" style="width: 100%; height: 400px;"></div>
    The chart will automatically conform to the container size by default.

    Instantiate a chart with some static data.

    const chart = new JSC.Chart('chartDiv', { 
        points: [{ x: 'A', y: 10 }, { x: 'B', y: 5 }]

    Get some data

    JSC.fetch() is an alias for vanilla JS fetch() function but includes a polyfill for IE11. This function makes it easy to get data for the chart.

        .then(response => response.text())
        .then(text => {
            //Use csv text 

    If data is transferred as csv, tsv or any delimiter separated values, it can be converted to JSON format. See the fetch(), CSV, and JSON tutorial for more information.

    let data = JSC.csv2Json(
    // -> 
    // [ {date: 1514786400000, actual: 5409, goal: 7000},
    // {date: 1514872800000, actual: 4893, goal: 7000} ]

    Map data to chart points

    let points = data.map(d => {  
      return { x: d.date, y: d.actual }; 
    //-> [{ x: 1514786400000, y: 5409 }, { x: 1514872800000, y: 4893 }]

    Render a chart using data

    const chart = new JSC.Chart('chartDiv', {
        // Pass points to the series
        series: [{
            points: points
        // Set the x axis scale to time.
        xAxis_scale_type: 'time'

    Crash Course

    (5 min read to hit the ground running)

    The JSCharting API is designed with ease of use in mind. The chart attempts to select default options that are obvious to reduce the need to customize.

    Chart Types

    Chart types can be set easily through options such as:

    const chart = new JSC.Chart('divId', { type:'line step' });

    Examples of chart type settings:

    • 'horizontal column aqua' - Horizontal columns with aqua shading
    • 'gauge linear horizontal' - Horizontal linear gauges.
    • 'radar polar column' - Polar radar chart with columns.

    More information


    Chart options are set in the chart constructor

    const chart = new JSC.Chart('divId', { /*options*/ });

    Or at any time after the chart is rendered with

    chart.options({ /*options*/ });

    Property Expansion

    JSCharting offers a declarative API with options such as

    chart.options({ title: { label: { text: 'title text' }}});

    However, property paths can be combined into single property names as follows:

    chart.options({ title_label_text: 'title text' });

    Property Expansion Details

    Hide Legend

    chart.options({ legend_visible: false });

    Legend Columns

    //Less Detail
    chart.options({ legend_template: '%icon %name' });
    //More Detail
    chart.options({ legend_template: '%average %sum %icon %name' });

    Legend Entries for Points

    The following code snippet sets a series palette which causes each point in a series to have an entry in the legend box.

    chart.options({ defaultSeries_palette: 'default' });

    Legend Tutorial


        //Title text
        title_label_text:'Title text',
        //Axis label text
        //Point labels
            label_text:'Annotation text'

    Using Labels

    Chart with a button

    Quickly add UI elements to make charts more interactive.

    JSC.Chart('chartDiv', { 
        toolbar_items: {
            'Click Me': {
                events_click: function(){ alert('Button clicked');}
