Inside this article, we will see the concept of Google Pie Chart Integration in Laravel 8. This article will be step by step graph integration.

Pie chart represents the information in very graphical view which provides the complete idea about data. We will use Google charts to add Pie chart into Laravel 8 application.

Let’s get started.


Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

$ composer create-project --prefer-dist laravel/laravel blog

To start the development server of Laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.


Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Create Model & Migration

We will consider users table to work with this Pie chart tutorial.

By default, you should see the users table migration (2014_10_12_000000_create_users_table.php inside /database/migrations folder) and User.php model in /app/Models.

We will work with these files.

Run Migration

Next, we need to create tables inside database.

$ php artisan migrate

This command will create tables inside database.


Dummy Data for Application

Here, you need to copy the given mysql query and run into sql tab of phpmyadmin.

--
-- Dumping data for table `users`
--

INSERT INTO `users` (`id`, `name`, `email`, `email_verified_at`, `password`, `remember_token`, `created_at`, `updated_at`) VALUES
(1, 'Emilie Mante', 'kwiegand@example.com', '2021-04-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', 'Y3FP2DroH6', '2021-04-02 17:43:37', '2021-04-02 17:43:37'),
(2, 'Reyna Stroman II', 'schuster.carlos@example.com', '2021-04-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', '8tDlUix4oY', '2021-02-26 17:43:37', '2021-02-26 17:43:37'),
(3, 'Prof. Lauriane Yost I', 'greta69@example.com', '2021-04-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', 'z6nEz8FkN6', '2021-01-02 17:43:37', '2021-01-02 17:43:37'),
(4, 'Zelma Yundt', 'ricardo.cartwright@example.com', '2021-04-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', 'RsOsNYIogy', '2021-04-02 17:43:37', '2021-04-02 17:43:37'),
(5, 'Hayley Lebsack', 'elna.tillman@example.com', '2021-07-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', '203SAe79eI', '2021-07-10 17:43:37', '2021-07-10 17:43:37'),
(6, 'Topmse Lebsack', 'topse.tillman@net.com', '2021-01-02 17:43:37', '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', '203SAe79eI', '2021-01-10 17:43:37', '2021-01-10 17:43:37');

You will see something like this after this test data insertion.


Create Controller

Next, we need to create a controller file.

$ php artisan make:controller UserController

It will create a file UserController.php at /app/Http/Controllers folder.

Open UserController.php and write this complete code into it.

<?php

namespace App\Http\Controllers;

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

class UserController extends Controller
{
    public function index()
    {
        $data['pieChart'] = User::select(\DB::raw("COUNT(*) as count"), \DB::raw("MONTHNAME(created_at) as month_name"))
        ->whereYear('created_at', date('Y'))
        ->groupBy('month_name')
        ->orderBy('count')
        ->get();
 
        return view('pie-chart', $data);
    }
}

Concept

User::select(DB::raw("COUNT(*) as count"), DB::raw("MONTHNAME(created_at) as month_name"))
    ->whereYear('created_at', date('Y'))
    ->groupBy('month_name')
    ->orderBy('count')
    ->get();

The date(‘Y’) returns the current year. That’s why In test data, we have taken the year as 2021 so that we can get a pie chart on the behalf of sample data. If your current is different then you will not be able to see the pie chart view on output.


Create Blade Layout File

Go to /resources/views folder and create a file with name pie-chart.blade.php

Open pie-chart.blade.php and write this complete code into it.

<!doctype html>
<html lang="en">
  <head>
    <title>Google Pie Chart Integration in Laravel 8</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
  </head>
	<body>
		<div class="container">
            <div id="pie-chart" style="width: 900px; height: 500px"></div> 
		</div>
		<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
		<script type="text/javascript">
			google.charts.load('current', {'packages':['corechart']});
			google.charts.setOnLoadCallback(drawChart);
	 
			function drawChart() {
	 
			var data = google.visualization.arrayToDataTable([
				['Month Name', 'Registered User Count'],
	 
					@php
					foreach($pieChart as $d) {
						echo "['".$d->month_name."', ".$d->count."],";
					}
					@endphp
			]);
	 
			  var options = {
				title: 'Users Detail',
				is3D: false,
			  };
	 
			  var chart = new google.visualization.PieChart(document.getElementById('pie-chart'));
	 
			  chart.draw(data, options);
			}
		  </script>
	</body>
</html>

Create Route

Open web.php from /routes folder and add this route into it.

# Add this to header
use App\Http\Controllers\UserController;

//...

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

Application Testing

Open project to terminal and type the command to start development server

$ php artisan serve

URL: http://127.0.0.1:8000/pie-chart
