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

Create Model & Migration

Open project into terminal and run this command to create model & migration file.

$ php artisan make:model Order -m

It will create two files –

  • Model – Order.php at /app/Models folder
  • Migration file – 2022_03_25_123805_create_orders_table.php at /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()
    {
        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()
    {
        Schema::dropIfExists('orders');
    }
};

Run Migration

Next, we need to migrate migration files.

$ php artisan migrate

This command will create tables inside database.

It will create orders table in database.

Dummy Data for Application

Next,

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

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

INSERT INTO `orders` (`id`, `product_name`, `product_id`, `price`, `created_at`, `updated_at`) VALUES
(1, 'Product 1', '5483TY', '120', '2022-03-06 18:30:00', NULL),
(2, 'Product 2', '45TRGF', '523', '2022-03-08 18:30:00', NULL),
(3, 'Product 3', 'FDFG5656', '236', '2022-03-11 18:30:00', NULL),
(4, 'Product 4', 'FDGT677', '450', '2022-03-13 18:30:00', NULL);

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

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 GraphController

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

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

<?php

namespace App\Http\Controllers;

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

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

Create Template File

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

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

        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>

Add Route

Open web.php file from /routes folder. Add this route into it.

//...

use App\Http\Controllers\GraphController;

//...

Route::get('google-bar-chart', [GraphController::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/google-bar-chart
