React Native Chart Kit

This is an example to create 7 Different Type of Graph using React Native Chart Kit for Android and IOS. Charts/Graphs are the easiest and efficient way to showcase any data. With the help of the chart/graph, One can easily see the numeric data or the statics. The understanding of the statics using the Chart/Graph makes it more demanding for any application. You have generally seen charts in the accounting apps like expense sharing. If you are planning to make your own app that needs to create the Chart/Graph then here is the example for you.

For Pie chart in your project then you can visit Example to Make 3 Different Type of Pie Chart in React Native and for Speedometer graph visit visualize data with Speedometer Graph in React Native.

For this example, we are going to use React Native Chart Kit, which is very simple and easy to integrate.

Type of Chart / Graph

You can use React Native Chart Kit to make the following type of Chart / Graph:

Bezier LineChart

For this example, We are going to create all these examples in a single screen with a scroll view.

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 Dependencies

To use LineChart, BarChart, PieChart, ProgressChart, ContributionGraph, StackedBarChart we need to install react-native-chart-kit and react-native-svg dependencies.

To install these open the terminal and jump into your project using

cd ProjectName

Run the following command to install

npm install react-native-chart-kit --save

npm install react-native-svg --save

These commands will copy all the dependencies into your node_module directory.

CocoaPods Installation

After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. So to install pods use

cd ios && pod install && cd ..

Code

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

App.js

// 7 Type of Graph using React Native Chart Kit
// https://aboutreact.com/react-native-chart-kit/

// import React in our code
import React from 'react';

// import all the components we are going to use
import {
  SafeAreaView,
  Text,
  View,
  StyleSheet,
  Dimensions,
  ScrollView,
} from 'react-native';

//import React Native chart Kit for different kind of Chart
import {
  LineChart,
  BarChart,
  PieChart,
  ProgressChart,
  ContributionGraph,
  StackedBarChart,
} from 'react-native-chart-kit';
