Google Bar Charts are an excellent tool for visualising data in web applications, particularly for comparing data across multiple categories or groups. To generate dynamic and interactive bar charts, Laravel, a sophisticated PHP framework, can be easily linked with Google Charts.

We will walk you through the process of using Google Bar Charts in Laravel 10, allowing you to present data in an educational and visually appealing manner.

Throughout this article, we’ll look at how to set up a Laravel project, integrate Google Charts, and create dynamic bar charts that can display data in real time.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

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

Setup Model & Migration

Open project into terminal and run this command,

php artisan make:model Order -m

It will create two files,

  • Model – Order.php inside /app/Models folder
  • Migration file – xxx_create_orders_table.php inside /database/migrations folder.

Open migration file and write this complete code into it,

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void
    {
        Schema::create('orders', function (Blueprint $table) {
            $table->id();
            $table->string("product_name")->nullable();
            $table->string("product_id")->nullable();
            $table->string("price")->nullable();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down(): void
    {
        Schema::dropIfExists('orders');
    }
};

Run Migration

Next, you need to migrate migration files,

php artisan migrate

This command will create tables inside database.

It will create orders table in database.

Next,

Prepare Dummy Data for Graph

You need to copy the given mysql query and run into sql tab of phpmyadmin. This will give us a set of data,

--
-- Dumping data for table `orders`
--

INSERT INTO `orders` (`id`, `product_name`, `product_id`, `price`, `created_at`, `updated_at`) VALUES
(1, 'Product 1', '5483TY', '120', '2023-02-06 18:30:00', NULL),
(2, 'Product 2', '45TRGF', '523', '2023-02-08 18:30:00', NULL),
(3, 'Product 3', 'FDFG5656', '236', '2023-02-11 18:30:00', NULL),
(4, 'Product 4', 'FDGT677', '450', '2023-02-13 18:30:00', NULL);

Right now, you have only these few rows of dummy data. But you can take more rows in it. These data will help to draw graph between Product and Price according to Order ID.

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

Create Data Controller

Next, you need to create a controller class,

php artisan make:controller GraphController

It will create a file GraphController.php inside /app/Http/Controllers folder.

Open file and write this complete code into it,

<?php

namespace App\Http\Controllers;

use App\Models\Order;
use Illuminate\Http\Request;
use Illuminate\View\View;

class GraphController extends Controller
{
    public function index(): View
    {
        $orders = Order::all();
      
        return view('google-bar-chart', ['orders' => $orders]);
    }
}

Create Blade Template File

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

Open file and write this complete code into it,

<!doctype html>
<html lang="en">

        });
        google.charts.setOnLoadCallback(drawChart);

        function drawChart() {
            var data = google.visualization.arrayToDataTable([
                ['Order Id', 'Price', 'Product Name'],

                @php
                    foreach ($orders as $order) {
                        echo "['" . $order->id . "', '" . $order->price . "', '" . $order->product_name . "'],";
                    }
                @endphp
            ]);

            var options = {
                chart: {
                    title: 'Bar Graph | Price',
                    subtitle: 'Price, and Product Name: @php echo $orders[0]->created_at @endphp',
                },
                bars: 'vertical'
            };
            var chart = new google.charts.Bar(document.getElementById('barchart_material'));
            chart.draw(data, google.charts.Bar.convertOptions(options));
        }
    </script>

</body>

</html>
