    A web component wrapper around the ZingChart library.


    Install the zingchart-web-component package via npm

    $ npm install zingchart-web-component

    Include in your project

    This web component exposes out the main <zing-chart> web component, as well as chart-specific components such as <zc-line> for readability and convenience.

    Depending on how you include this package, your inclusion will be different.

    Import Modules

    Import the generic zingchart component

    import ZingChart from 'zingchart-web-component';
    customElements.define('zing-chart', ZingChart);


    Manually import each chart and register it as a web component.

    import {Line} from 'zingchart-web-component/charts/ZCLine.js';
    customElements.define('zc-line', Line);


    The ZingChart web component is a fully functional web component and exposes all methods and events.

    A simple hello world

    Below is the most simple and straightforward way to get a chart rendered on your page:

    <zing-chart data='{"type": "line", "series": {["values": 1,2,3,4,5,6,4]}}'></zing-chart>

    The data attribute takes the exact same JSON that the ZingChart library uses.

    We can also simplify the example by using our line chart component:

    <zc-line data='"series": [{"values": [1,2,3,4,5,6,4]}]'></zc-line>

    Note the absence of an "id" property. We autogenerate an id property so you don't have to (you can still provide one).

    The web-component way

    While everything can be configured via the data property, you can also fully configure ZingChart via child components.

    Each configuration property that ZingChart accepts can also be used as a child-component prefixed by 'zc-'.

    For instance, if we want to set our data for our chart with a component, we would use the zc-series-# components:

          <zc-series-0 values="[3,4,3,2,4,3,3]"></zc-series-0>

    Similarly, if we wanted to add a draggable legend, we would simply add the following:

        <zc-legend draggable></zc-legend>
          <zc-series-0 values="[3,4,3,2,4,3,3]"></zc-series-0>

    The structure of the web-component mirrors the JSON configuration that ZingChart provides, and every property is available at each level.

    For objects that accept arrays, simply use a parent component just as you would in the JSON syntax. Below is an example of adding custom labels:

        <zc-label x="15%" y="5%" font-size="22px" border-width="1px" font-color="black" font-family="Times">First Label</zc-label>
        <zc-label x="15%" y="10%" font-size="22px" border-width="1px" font-color="red">Second Label</zc-label>


    Currently the height, width, data, series, and values are watched and will re-render the chart if changed. Future support for all attributes is planned.


    All methods are available via the instance of the component. The methods are simplified and do not require an id like in the JavaScript version.

    zingchart.exec('myChart', 'setseriesvalues', {
      values: [
        [19, 28, 13, 42, ...],
        [37, 11, 27, 25, ...]
    const chart = document.querySelector('zing-chart');
      values: [
        [19, 28, 13, 42, ...],
        [37, 11, 27, 25, ...]


    Events can be attached to the root component, and passed a global function to send the event results to. All ZingChart events are available.

    window.chartRendered = function() {
      console.log('The chart is rendered!');
    <zing-chart complete="chartRendered"></zing-chart>
