A bar chart represents categorical data with corresponding data values as rectangular bars. Usually, the x-axis represents categorical values and the y-axis represents the data values or frequencies. This is called a vertical bar chart and the inverse is called a horizontal bar chart. In some cases, a horizontal bar chart provides better readability.

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 React from "react"; import { MDBContainer } from "mdbreact"; import { HorizontalBar } from "react-chartjs-2"; const App = () => { // Sample data const data = { labels: ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"], datasets: [ { label: "Hours Studied in Geeksforneveropen", data: [2, 5, 7, 9, 7, 6, 4], fill: true, backgroundColor: "rgba(6, 156,51, .3)", borderColor: "#02b844", } ] } return ( <MDBContainer> <HorizontalBar data={data} /> </MDBContainer> ); } 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:
