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
- LineChart
- Progress Chart
- Bar Chart
- StackedBar Chart
- Pie Chart
- Contribution Chart

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-cliRun the following commands to create a new React Native project
react-native init ProjectNameIf 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.Xreact-native init ProjectName --version react-native@nextThis 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 ProjectNameRun the following command to install
npm install react-native-chart-kit --savenpm install react-native-svg --saveThese 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

import { Text, View, StyleSheet, Dimensions, ScrollView } from 'react-native';
