Deprecation disclaimer

This project is no longer actively maintained

As of 01.01.2021, The React Native wrapper is no longer maintained by Highsoft. The repository will remain available, but we can not guarantee that it will work as intended with future releases of both React Native itself, or Highcharts.

Highcharts React Native

Official minimal Highcharts wrapper for React Native.

Getting Started

General prerequisites

Make sure you have Node.JS, NPM and React up to date. Tested and required versions:

node 11.2+
npm 6.7.0+ or similar package manager

Packages which should be installed within your project:

React >=16.4+
React Native >=0.63.2
React Native Webview >=10.6.0

If you're using this package with Expo Tools, please make sure your Expo SDK version is higher than or equal to v38.0.0, otherwise use the v2.2.3 version of this package, which should work from v33.0.0.

In bare React Native application you need to also install the react-native-unimodules package, and configure the content of ios and android build directiories like it's described here.

Installing

Get package from NPM in your React app:

npm install @highcharts/highcharts-react-native

You can either install this wrapper within app based on Expo tools, or bare React Native app.

It is required to add the .hcscript into the asset extensions section of metro.config.js file, or create that file within your project, and configure it like below:

const {getDefaultConfig} = require('metro-config');

module.exports = (async () => {
  const {
      resolver: { sourceExts, assetExts }
  } = await getDefaultConfig()
  return {
      transformer: {
          getTransformOptions: async () => ({
              transform: {
                  experimentalImportSupport: false,
                  inlineRequires: false
              }
          })
      },
      resolver: {
        sourceExts,
        assetExts: [...assetExts, 'hcscript']
      }
    }
})()

Updating Highcharts package

Since this package has been deprecated, we decided to meet our users' needs and created the update-highcharts script, which will get the latest Highcharts release and replace source files used by this wrapper, and let the community keep developing the highcharts-react-native package.

In order to run the update process, please run the following commands in this package directory:

npm i

and then

npm run update-highcharts

Usage

Basic usage example

Import this package into your React Native project and render the chart:

Highcharts chart

import React from 'react';
import { StyleSheet, View } from 'react-native';
import HighchartsReactNative from '@highcharts/highcharts-react-native'

export default class App extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            chartOptions: {
                series: [{
                    data: [1, 2, 3]
                }]
            }
        };
    }

    render() {
        return (
            <View style={styles.container}>
                <HighchartsReactNative
                    styles={styles.container}
                    options={this.state.chartOptions}
                />
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        backgroundColor: '#fff',
        justifyContent: 'center',
        flex: 1
    }
});

Highcharts live data update

import React from 'react';
import { StyleSheet, View } from 'react-native';
import HighchartsReactNative from '@highcharts/highcharts-react-native'

export default class App extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            chartOptions: {
                chart: {
                    events: {
                        load: function () {

                            // set up the updating of the chart each second
                            var series = this.series[0];
                            setInterval(function () {
                                var y = Math.random();
                                series.addPoint(y, true, true);
                            }, 1000);
                        }
                    }
                },
                series: [{
                    data: [1, 2, 3]
                }]
            }
        };
    }

    render() {
        return (
            <View style={styles.container}>
                <HighchartsReactNative
                    styles={styles.container}
                    options={this.state.chartOptions}
                />
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        backgroundColor: '#fff',
        justifyContent: 'center',
        flex: 1
    }
});

Using Highcharts modules e.g solid-gauge, drilldown, or exporting

import React from 'react';
import { StyleSheet, View } from 'react-native';
import HighchartsReactNative from '@highcharts/highcharts-react-native'

const modules = [
    'solid-gauge'
];

export default class App extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            chartOptions: {
                chart: {
                    type: 'solidgauge'
                },
                series: [{
                    data: [1]
                }]
            }
        };
    }

    render() {
        return (
            <View style={styles.container}>
                <HighchartsReactNative
                    styles={styles.container}
                    options={this.state.chartOptions}
                    modules={modules}
                />
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        backgroundColor: '#fff',
        justifyContent: 'center',
        flex: 1
    }
});

Optimal way to update

A good practice is to keep all chart options in the state. When setState is called, the options are overwritten and only the new ones are passed to the chart.update method.

import React from 'react';
import {
    StyleSheet,
    View,
    Button
} from 'react-native';
import HighchartsReactNative from '@highcharts/highcharts-react-native'

export default class App extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            chartOptions: {
                title: {
                    text: 'Default title'
                },
                tooltip: {
                    formatter: function () {
                        return 'Point Y: ' + this.y;
                    }
                },
                series: [{
                    data: [1, 3, 2]
                }]
            }
        };
    }

    chartUpdate() {
        this.setState({
            chartOptions: {
                title: {
                    text: 'Updated chart'
                },
                tooltip: {
                    formatter: function () {
                        return 'Point value: ' + this.y;
                    }
                }
            }
        });
    }

    render() {
        return (
            <View style={styles.container}>
                <HighchartsReactNative
                    styles={styles.container}
                    options={this.state.chartOptions}
                />
                <Button
                    onPress={this.chartUpdate.bind(this)}
                    title='Chart update'
                    color='#000'
                />
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        height: 200,
        backgroundColor: '#fff',
        justifyContent: 'center',
        flex: 1
    }
});

| Parameter | Type | Required | Description | | --------- | :----: | :--------: | ----------- | | styles | Object | no | You can style your container using JavaScript like in the regular react and react native. | | options | Object | yes | Highcharts chart configuration object. Please refer to the Highcharts API documentation. This option is required. | | modules | Array | no | List of modules which should be added to Highcharts. I.e when you would like to setup solidgauge series which requires highcharts-more and solid-gauge files, you should declare array: const modules = ['solid-gauge'] | | callback | Function | no | A callback function for the created chart. First argument for the function will hold the created chart. Default this in the function points to the chart. This option is optional. | | useCDN | Boolean | no | Set the flag as true, if you would like to load files (i.e highcharts.js) from CDN instead of local file system. You can declare an url to your domain (i.e mydomain.com/highchartsfiles/) | | useSSL | Boolean | no | Set the flag as true, if you would like to load files (i.e highcharts.js) by SSL. (The useCDN flag is mandatory). | | data | any | no | Data to be stored as global variable in Webview. | | onMessage | Function | no | Global communication between Webview and App. The function takes the message as the first argument. | | loader | Boolean | no | Set the flag to true, if you would like to show loader while chart is loading. | | webviewStyles | Object | no | You can style your webview using JavaScript object structured like in the regular React and React Native apps. | | webviewProps | Object | no | You can pass webview props. | | setOptions | Object | no | Options which are set for Highcharts through Highcharts.setOptions() method. Usually it is used to set the global and lang options. For more details please visit Highcharts documentation, and API. | | devPort | String | no | When using EXPO in DEV mode, you may declare address and port to actually load the html file in Android. You cannot use built-in file:/// when using Expo,because the Android and iOS folders don’t exist yet. When it’s in STAGING or PROD skip this option and use default the file:///android_asset path. |
