Now, we will plot a bar graph using the chart js library. so you can see the following steps for Laravel 8 Chart Js Example.

Overview

Step 1: Install Laravel 8
Step 2: Setting Database Configuration
Step 3: Create Routes
Step 4: Create Controller
Step 5: Create Blade Files
Step 6: Run Our Laravel Application

Step 1: Install Laravel 8

We are going to install laravel 8, so first open the command prompt or terminal and go to xampp htdocs folder directory using the command prompt. after then run the below command for laravel 8 install.

composer create-project --prefer-dist laravel/laravel laravel8_chart

1	composer create-project --prefer-dist laravel/laravel laravel8_chart

Step 2: Setting Database Configuration

After the complete installation of laravel. we have to database configuration. now we will open the .env file and change the database name, username, password in the .env file. See below changes in a .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=Enter_Your_Database_Name(laravel8_chart)
DB_USERNAME=Enter_Your_Database_Username(root)
DB_PASSWORD=Enter_Your_Database_Password(root)

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=Enter_Your_Database_Name(laravel8_chart)

DB_USERNAME=Enter_Your_Database_Username(root)

DB_PASSWORD=Enter_Your_Database_Password(root)

Step 3: Create Routes
Add the following route code in the “routes/web.php” file.

use App\Http\Controllers\UserController;

Route::get('chart',[UserController::class, 'index']);

use App\Http\Controllers\UserController;

Route::get('chart',[UserController::class, 'index']);

Step 4: Create Controller
Here below command help to create the controller and model.

php artisan make:controller UserController

1	php artisan make:controller UserController

UserController.php

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\User;
use DB;
use Carbon\Carbon;

class UserController extends Controller
{
    public function index()
    {
        $year = ['2015','2016','2017','2018','2019','2020'];

        $user = [];
        foreach ($year as $key => $value) {
            $user[] = User::where(\DB::raw("DATE_FORMAT(created_at, '%Y')"),$value)->count();
        }

    	return view('chart')->with('year',json_encode($year,JSON_NUMERIC_CHECK))->with('user',json_encode($user,JSON_NUMERIC_CHECK));
    }
}

?>

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\User;

use DB;

use Carbon\Carbon;

class UserController extends Controller

{

public function index()

{

$year = ['2015','2016','2017','2018','2019','2020'];

$user = [];

foreach ($year as $key => $value) {

$user[] = User::where(\DB::raw("DATE_FORMAT(created_at, '%Y')"),$value)->count();

}

return view('chart')->with('year',json_encode($year,JSON_NUMERIC_CHECK))->with('user',json_encode($user,JSON_NUMERIC_CHECK));

}

Step 5: Create Blade Files
So finally, first we need to create the chart.blade.php file in the “resources/views/” directory and update the below code.
chart.blade.php

    var user = <?php echo $user; ?>;
    var barChartData = {

        }]
    };

    window.onload = function() {
        var ctx = document.getElementById("canvas").getContext("2d");
        window.myBar = new Chart(ctx, {
            type: 'bar',
            data: barChartData,
            options: {
                elements: {
                    rectangle: {
                        borderWidth: 2,
                        borderColor: '#ffa0a0',
                        borderSkipped: 'bottom'
                    }
                },
                responsive: true,
                title: {
                    display: true,
                    text: 'Yearly User Joined'
                }
            }
        });
    };  
</script>
</body>
</html>

<!DOCTYPE html>

<html>

<head>

<title>Laravel 8 Chart Js Example From Scratch - XpertPhp</title>

</head>

<body>

</div>

var year = <?php echo $year; ?>;

var user = <?php echo $user; ?>;

var barChartData = {

labels: year,

datasets: [{

label: 'User',

backgroundColor: "pink",

data: user

}]

};

window.onload = function() {

var ctx = document.getElementById("canvas").getContext("2d");

window.myBar = new Chart(ctx, {

type: 'bar',

data: barChartData,

options: {

elements: {

rectangle: {

borderWidth: 2,

borderColor: '#ffa0a0',

borderSkipped: 'bottom'

}

responsive: true,

title: {

display: true,

text: 'Yearly User Joined'

}

});

};

</script>

</body>

</html>

Step 6: Run Our Laravel Application
We can start the server and run this example using the below command.

php artisan serve

1	php artisan serve

Now we will run our example using the below Url in the browser.

http://127.0.0.1:8000/chart
