How to implement a bar chart in React
In this article, we will explain to you how to implement a bar chart in React. As used in the previous article, we will use the Highcharts package to create bar chart using ReactJS.
Let’s take a simple example to create a bar chart with minimum configuration.
Implement a bar chart in React
1. Create a react application
First of all, we will create a react startup application using create-react-app npm package. Run the following command to create a react application.
1 | npx create-react-app bar-chart-react |
2. Add highcharts npm package
In the next step, we will install the Highcharts npm package to implement a bar chart. Run the following command to add the dependency in the application.
1 | npm i highcharts |
3. Create a bar chart
Now we will use the chart method of the highcharts package with minimum configuration to create a bar chart. Use the following options to create a chart.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 | { chart: { type: 'bar' }, // type of the chart title: { text: 'Bar Chart Title' }, // title of the chart subtitle: { text: 'Lorem Ipsum is simply dummy text' }, // subtitle of the chart xAxis: { categories: [ 'Y1', 'Y2', 'Y3', 'Y4', 'Y5' ], // the categories of the Y Axis title: { text: 'Y Axis Title' }, // the title of the Y Axis crosshair: true }, yAxis: { min: 0, // minimum value of the X Axis title: { text: 'X Axis Title' } // the title of the X Axis }, tooltip: { headerFormat: '<span style="font-size:10px">{point.key}</span><table>', pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' + '<td style="padding:0"><b>{point.y}</b></td></tr>', footerFormat: '</table>', shared: true, useHTML: true }, // tooltip appears when hovering over a point credits: { enabled: false }, series: dataSource // set of the data } |
Here, X axis and Y axis values are slightly different from the Column Chart. Check out this link for more information about the options.
Now let’s assume that we are receiving the data source from the API response. To mimic the scenario, we will use the setTimeout method to set the dataSource after 2 seconds.
App.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 | import React, { useEffect, useRef, useState } from 'react'; import Highcharts from 'highcharts'; function App() { const refContainer = useRef(null); const [dataSource, setDataSource] = useState([]); useEffect(() => { const chart = Highcharts.chart(refContainer.current, { chart: { type: 'bar' }, // type of the chart title: { text: 'Bar Chart Title' }, // title of the chart subtitle: { text: 'Lorem Ipsum is simply dummy text' }, // subtitle of the chart xAxis: { categories: [ 'Y1', 'Y2', 'Y3', 'Y4', 'Y5' ], // the categories of the Y Axis title: { text: 'Y Axis Title' }, // the title of the Y Axis crosshair: true }, yAxis: { min: 0, // minimum value of the X Axis title: { text: 'X Axis Title' } // the title of the X Axis }, tooltip: { headerFormat: '<span style="font-size:10px">{point.key}</span><table>', pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' + '<td style="padding:0"><b>{point.y}</b></td></tr>', footerFormat: '</table>', shared: true, useHTML: true }, // tooltip appears when hovering over a point credits: { enabled: false }, series: dataSource // set of the data }); if (dataSource.length > 0) { chart.hideLoading(); } else { chart.showLoading(); } }, [dataSource]); useEffect(() => { setTimeout(() => { setDataSource([{ name: 'Japan', data: [50, 72, 88, 92, 34] }, { name: 'Germany', data: [84, 79, 99, 94, 66] }, { name: 'London', data: [49, 39, 47, 40, 42] }, { name: 'Canada', data: [43, 34, 77, 35, 53] }]); }, 2000); }, []); return ( <div className="App"> <h3>Bar chart in React - <a href="http://www.cluemediator.com" target="_blank" rel="noopener noreferrer">Clue Mediator</a></h3> <div ref={refContainer} /> </div> ); } export default App; |
Here, we used the refs to load the chart in div element.
4. Output
Run the application and check the output in the browser.
That’s it for today.
