React

zingchart-react is an React JavaScript directive to allow ZingChart to work dynamically with data. Quickly add charts to your React application with our ZingChart component. This guide assumes some basic working knowledge of React. You can view the full component on github or npm.

1. Install

Install the zingchart-react package via npm

$ npm install zingchart-react

2. Include the component in your project

You can either include the zingchart-react component to your project globally or locally per component

Locally per component (recommended)

In each component where ZingChart is being used, include the following in your component's configuration:

import 'zingchart/es6';
import ZingChart from 'zingchart-react';
// EXPLICITLY IMPORT MODULE
import 'zingchart-react/dist/modules/zingchart-depth.min.js';

class App extends Component {
    ...
}

We recommend this approach if ZingChart is only included in a few, un-related pages across your application.

Globally

You can either include the zingchart-react component to your project via UMD in your main index.html file, include the package as a script include.

<script src="/path/to/zingchart.min.js"></script>
<script src="/path/to/zingchart-react.js"></script>

This will register the zingchart component globally throughout your application. While the easiest installation option, this will load ZingChart immediately on your user's first load of the application - regardless if a chart is on the first page or not. We recommend this approach if ZingChart is used heavily across multiple pages.

Usage

The zingchart-react component can be included into render() as an element. Below is a simple example of a bar chart:

render() {
    return (
      <div >
        <ZingChart data={this.state.config}/>
      </div>
    );
  }

Whole class configuration:

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      config: {
        type: 'bar',
        series: [{
          values: [4,5,3,4,5,3,5,4,11]
        }]
      }
    }
  }
  render() {
    return (
      <div >
        <ZingChart data={this.state.config}/>
      </div>
    );
  }

}

Parameters

data [object]

<zingchart :data="myData" :series="mySeries"></zingchart>
const myData = {
    type: 'line',
    series: [
      { values: [1,2,4,5,6] }
    ]
};

<zingchart data={myData}></zingchart>

id [string] (optional)

The id for the DOM element for ZingChart to attach to. If no id is specified, the id will be autogenerated in the form of zingchart-react-#

output [string] (optional)

The render type for the visualization. Either svg (default) or canvas

series [array] (optional)

Accepts an array of series objects, and overrides a series if it was supplied into the config object. Varies by chart type used - Refer to the ZingChart documentation for more details.

const myData = {
    type: 'line',
};

const mySeries = [
  { values: [1,2,4,5,6] }
];

<zingchart data={myData} series={mySeries}></zingchart>

width [string or number] (optional)

The width of the chart. Defaults to 100%

height [string or number] (optional)

The height of the chart. Defaults to 480px.

theme [object] (optional)

The theme or 'defaults' object defined by ZingChart. More information available here: https://www.zingchart.com/docs/api/themes

Events

All zingchart events are readily available on the component to listen to. For example, to listen for the 'complete' event when the chart is finished rendering:

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      config: {
        type: 'line',
        series: [{
          values: [4,5,3,4,5,3,5,4,11]
        }]
      }
    }
    this.chartDone = this.chartDone.bind(this);
  }
  render() {
    return (
      <div>
        <ZingChart data={this.state.config} complete={this.chartDone}/>
      </div>
    );
  }
  chartDone(event) {
    console.log(`Event "Complete" - The chart is rendered\n`);
  }
}

For a list of all the events that you can listen to, refer to the complete documentation on https://www.zingchart.com/docs/events

Methods

All zingchart methods are readily available on the component's instance to call. For example, to add a new plot node to the chart:

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      config: {
        type: 'bar',
        series: [{
          values: [4,5,3,4,5,3,5,4,11]
        }]
      }
    };
    this.chart = React.createRef();
    this.addPlot = this.addPlot.bind(this);

  }
  render() {
    return (
      <div>
        <ZingChart ref={this.chart} data={this.state.config}/>
        <button onClick={this.addPlot}>AddPlot</button>
      </div>
    );
  }
  addPlot() {
    this.chart.current.addplot({
      data: {
        values: [5,3,3,5,6,4,3,4,6],
        text: "My new plot"
      }
    });
  }
}
