Example to Make 3 Different Type of Pie Chart in React Native

React Native Pie Chart

This is an Example to Make 3 Different Type of Pie Chart in React Native. React Native Pie Chart can be made using the library react-native-pie. If you are making an app that has numbers and lots of statics to show then charts are the best way to show that data. Pie Charts are best to use when you are trying to compare different parts of a whole. They do not show changes over time. Here is the Example to make Pie Chart in your React Native App.

If you want to explore more Charts then you can visit 7 Type of Graph using React Native Chart Kit and for Speedometer graph visit visualize data with Speedometer Graph in React Native.

To make a Pie Chart we are going to use a react-native-pie library. It will provide a Pie component which is very easy to integrate. You can see the example below.

How to use Pie component?

<Pie
     radius={70}
     //completly filled pie chart with radius 70
     series={[10, 20, 30, 40]}
     //values to show and color sequentially
     colors={['#f00', '#0f0', '#00f', '#ff0']}
/>

In this example, We are going to make a Solid/Filled Pie Chart, Donut Pie Chart, and Gauge Pie Chart. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

1. To use Pie component, you need to install react-native-pie package.

To install this open the terminal and jump into your project

cd ProjectName

Run the following command

npm install react-native-pie --save

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named react-native-pie.

–save is optional, it is just to update the react-navigation dependency in your package.json file.

2. For this project, we have to link the ART library for iOS. To Link, the ART library for the IOS open the ProjectName.xcworkspace in Xcode

3. You will see Project Structure in Left Menu. Click on the Libraries option to expand.

4. Navigate to node_modules/react-native/Libraries/ART/ART.xcodeproj and drag ART.xcodeproj into the Libraries

5. Now expand the ART.xcodeproj and navigate to Products. You will see libART.a. Click on the Project in the left sidebar (PieChartExample in this case), now find Build Phase tab in the workspace area where you can see Link Binary With Libraries. (Please make note that  you have selected the Project and then opening the Build Phase)

6. Now drag the libART.a file into the Link Binary With Libraries.

That’s it! Now we are ready to proceed for the next step.

Code to Make a Pie Chart in React native

Now Open App.js in any code editor and replace the code with the following code

App.js

//This is an example code for PieChart//
import React, { Component } from 'react';
//import react in our code.
import { StyleSheet, View, Text } from 'react-native';
// import all basic components
import Pie from 'react-native-pie';
// import pie to make pie chart

export default class App extends Component {
  render() {
    return (
      <View style={styles.container}>
      <Text>Pie Chart Example</Text>
        <Pie
          radius={70}
          series={[56, 11, 77]}
          colors={['yellow', 'green', 'orange']}
        />
        <Text>Solid/Filled Pie Chart</Text>
        <Pie
          radius={70}
          innerRadius={40}
          series={[10, 20, 30, 40]}
          colors={['#f00', '#0f0', '#00f', '#ff0']}
        />
        <Text>Donut Pie Chart</Text>
        <View>
          <Pie
            radius={70}
            innerRadius={65}
            series={[55]}
            colors={['#f00']}
            backgroundColor="#ddd"
          />
          <View style={styles.gauge}>
            <Text style={styles.gaugeText}>55%</Text>
          </View>
          <Text>Gauge Pie Chart</Text>
        </View>
      </View>
    );
  }
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'space-around',
    marginTop:30,
  },
  gauge: {
    position: 'absolute',
    width: 140,
    height: 140,
    alignItems: 'center',
    justifyContent: 'center',
  },
  gaugeText: {
    backgroundColor: 'transparent',
    color: '#000',
    fontSize: 24,
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).

    • We have no option to make the label in the center in this library. If you want to make the center label you have to manage on your own.
      For an idea you can use below hint
      <View (style-> Align center/Justify center/text center )>
      <PieChart></PieChart>
      <Text>Text You want</Text>
      </View>
