In our React app sometimes we want to display a BarChart representation of a particular data. We can use react-chartjs-2 and chart.js module in ReactJS to display information in BarCharts format. Following are some simple steps to do so:
Step 1: Create a React application using the following command.
npx create-react-app BARCHART_REACT
Step 2: After creating your project folder i.e. BARCHART_REACT, move to it using the following command.
cd BARCHART_REACT
Step 3: After creating the ReactJS application, Install react-chartjs-2 and chart.js modules using the following command.
npm install --save react-chartjs-2 chart.js
Project structure:
Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.
App.js
import { Bar } from "react-chartjs-2";   function App() {   return (     <div className="App">       <h1>GEEKSFORGEEKS BAR CHART REACTJS</h1>       <div style={{ maxWidth: "650px" }}>         <Bar           data={{             // Name of the variables on x-axies for each bar             labels: ["1st bar", "2nd bar", "3rd bar", "4th bar"],             datasets: [               {                 // Label for bars                 label: "total count/value",                 // Data or value of your each variable                 data: [1552, 1319, 613, 1400],                 // Color of each bar                 backgroundColor: ["aqua", "green", "red", "yellow"],                 // Border color of each bar                 borderColor: ["aqua", "green", "red", "yellow"],                 borderWidth: 0.5,               },             ],           }}           // Height of graph           height={400}           options={{             maintainAspectRatio: false,             scales: {               yAxes: [                 {                   ticks: {                     // The y-axis value will start from zero                     beginAtZero: true,                   },                 },               ],             },             legend: {               labels: {                 fontSize: 15,               },             },           }}         />       </div>     </div>   ); }   export default App; |
Step to Run Application: Run the application using the following command from the root directory of the project:
npm start
Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
