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 './App.css';
import {
    LineChart,
    ResponsiveContainer,
    Legend, Tooltip,
    Line,
    XAxis,
    YAxis,
    CartesianGrid
} from 'recharts';

// Sample chart data
const pdata = [
    {
        name: 'MongoDb',
        student: 11,
        fees: 120
    },
    {
        name: 'Javascript',
        student: 15,
        fees: 12
    },
    {
        name: 'PHP',
        student: 5,
        fees: 10
    },
    {
        name: 'Java',
        student: 10,
        fees: 5
    },
    {
        name: 'C#',
        student: 9,
        fees: 4
    },
    {
        name: 'C++',
        student: 10,
        fees: 8
    },
];

function App() {
    return (
        <>
            <h1 className="text-heading">

            </h1>
            <ResponsiveContainer width="100%" aspect={3}>
                <LineChart data={pdata} margin={{ right: 300 }}>
                    <CartesianGrid />
                    <XAxis dataKey="name"
                        interval={'preserveStartEnd'} />
                    <YAxis></YAxis>
                    <Legend />
                    <Tooltip />
                    <Line dataKey="student"
                        stroke="black" activeDot={{ r: 8 }} />
                    <Line dataKey="fees"
                        stroke="red" activeDot={{ r: 8 }} />
                </LineChart>
            </ResponsiveContainer>
        </>
    );
}

export default App;
