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 any application. You have generally seen charts in the accounting apps like expense sharing. If you are planning to make your own app which 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. 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.
1. 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-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
1 | cd ProjectName |
Run the following command to install
1 | npm install react-native-chart-kit --save |
1 | 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
1 | cd ios && pod install && cd .. |
Now Open App.js in any code editor and replace the code with the following code.
App.js

To Run the React Native App
Open the terminal again and jump into your project using.cd ProjectNamereact-native run-androidreact-native run-ios (macOS only).Screenshots
This is how you can make 7 Type of Graph using React Native Chart Kit for Android and IOS. If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned! Hope you liked it. 🙂
