react-native-pie-chart

react-native-pie-chart

Simple pie chart module for your React Native app, for both iOS and Android.

Installation

You need to have react, react-native and @react-native-community/art as your app's dependencies.

~$ npm install react-native-pie-chart --save

For react-native versions older than 0.60 you need to manually install and link @react-native-community/art:

~$ npm install @react-native-community/art --save
~$ react-native link @react-native-community/art

Refer to their project repository for more information: https://github.com/react-native-art/art

Usage

Here's a quick start code. Refer to the example directory for a fully working app.

import React, { Component } from 'react';
import { StyleSheet, ScrollView , StatusBar, Text, View } from 'react-native';
import PieChart from 'react-native-pie-chart';

export default class TestChart extends Component {
  render() {
    const widthAndHeight = 250
    const series = [123, 321, 123, 789, 537]
    const sliceColor = ['#F44336','#2196F3','#FFEB3B', '#4CAF50', '#FF9800']

    return (
      <ScrollView style={{flex: 1}}>
        <View style={styles.container}>
          <Text style={styles.title}>Basic</Text>
          <PieChart
            widthAndHeight={widthAndHeight}
            series={series}
            sliceColor={sliceColor}
          />
          <Text style={styles.title}>Doughnut</Text>
          <PieChart
            widthAndHeight={widthAndHeight}
            series={series}
            sliceColor={sliceColor}
            doughnut={true}
            coverRadius={0.45}
            coverFill={'#FFF'}
          />
        </View>
      </ScrollView>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center'
  },
  title: {
    fontSize: 24,
    margin: 10
  }
});

Example App

Have a look at the app in the example directory for how to write a simple app that shows two charts. To setup and run the example app follow these instructions:

# Clone package
~$ git clone https://github.com/genexu/react-native-pie-chart.git

# Setup ART and dependencies
~$ cd react-native-pie-chart/example
~$ npm install

# Run simulator
# Notice: plz make sure your simulator state is normal
~$ npx react-native run-ios
~$ npx react-native run-android

TypeScript

The npm package includes TypeScript types.

Upgrading from version one

The only breaking change between version one and two is chart_wh prop. It is renamed to widthAndHeight. Beside that, there shouldn't be any issue upgrading.
