Radar charts, also known as spider or star charts, provide a powerful way to display data having multiple variable in a circular layout. Recharts is a popular charting library that is used for creating charts for React JS, provides an easy and efficient method to implement radar charts within your React applications.
Prerequisites:
- Basic understanding of ReactJS and its concepts.
- A React project set up with Recharts installed.
Approach: To create Radar chart using Recharts, we create a dataset with label and polar coordinate details. Then we create a polar grid and both axes i.e. polarAngle axis and polarRadius axis using data coordinates. Finally using the Radar element draws the Radar plot.
Creating React Application And Installing Module:
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 React from 'react' ;
import { Radar, RadarChart, PolarGrid,
PolarAngleAxis, PolarRadiusAxis } from 'recharts' ;
const App = () => {
const data = [
{ name: 'A' , x: 21 },
{ name: 'B' , x: 22 },
{ name: 'C' , x: -32 },
{ name: 'D' , x: -14 },
{ name: 'E' , x: -51 },
{ name: 'F' , x: 16 },
{ name: 'G' , x: 7 },
{ name: 'H' , x: -8 },
{ name: 'I' , x: 9 },
];
return (
<RadarChart height={500} width={500}
outerRadius= "80%" data={data}>
<PolarGrid />
<PolarAngleAxis dataKey= "name" />
<PolarRadiusAxis />
<Radar dataKey= "x" stroke= "green"
fill= "green" fillOpacity={0.5} />
</RadarChart>
);
}
export default App;
|
Step to Run the 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:
Radar chart
