Friends now I proceed onwards and here is the working code snippet for Reactjs Chartjs with Dynamic Data and please use this carefully to avoid the mistakes:

1. Firstly, we need fresh reactjs setup and for that, we need to run below commands into out terminal and also we should have latest node version installed on our system:

npx create-react-app reactchart

cd reactchart

2. Now we need to run below commands into our project terminal to get chartjs and related modules into our reactjs application:

npm install --save react-chartjs-2

npm install chart.js --save

npm install axios

npm start //For start project

3. Finally for the main output, we need to add below code into our reactchart/src/App.js file or if you have fresh setup then you can replace reactchart/src/App.js file code with below code:

import React from 'react';
import {Bar} from 'react-chartjs-2';
import axios from 'axios';
class Home extends React.Component {
    constructor(props) {
        super(props)
          this.state = {
            months: [],
            sales:[]
                  }
          }
     
      componentDidMount(){
        //Get all chart details
        axios.get('http://localhost/chartjs.php').then(res => 
        {
        //Storing users detail in state array object
        this.setState({months: res.data[0]});
        this.setState({sales: res.data[1]});
           }); 
       
        
        }
    
 
  render() {
   
    return (
     
    <div className="maincontainer">

       
            <Bar
                data={{
                    labels: this.state.months,
                    datasets: [
                      {
                        label: 'Sales',
                        backgroundColor: 'rgba(75,192,192,1)',
                        borderColor: 'rgba(0,0,0,1)',
                        borderWidth: 2,
                        data: this.state.sales
                      }
                    ]
                  }}
                options={{
                    title:{
                    display:true,
                    text:'Average Rainfall per month',
                    fontSize:20
                    },
                    legend:{
                    display:true,
                    position:'right'
                    }
                }}
                />

           




    </div>
     
      
)
};
}

export default Home;

 

4. Guys here is my chartjs.php file data and this file is located inside xampp/htdocs folder::

<?php
header('Access-Control-Allow-Origin: *');
header('Content-Type: application/json');
  
  $months = array("January", "February", "March", "April", "May", "June", "July");
  $sales = array("45", "55", "35", "65", "60", "25", "45");
  echo json_encode(array($months,$sales));
  die();
?>

Now we are done friends. If you have any kind of query or suggestion or any requirement then feel free to comment below.

Note: Friends, I just tell the basic setup and things, you can change the code according to your requirements. For better understanding must watch video above.
