In the field of web application development, data visualisation is critical to efficiently communicating information to consumers. Google Line Charts are a wonderful tool for creating interactive and interesting data visualisations, and Laravel, a versatile PHP framework, provides an excellent base for easily integrating these charts into your apps.

We will walk you through the process of integrating Google Line Charts into Laravel 10, allowing you to present data in a visually engaging and dynamic manner.

By the end of this lesson, you will have the skills and expertise to efficiently integrate Google Line Charts into Laravel 10, allowing you to create web applications that provide data trends and insights to your users in a dynamic and engaging way.

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 terminal and run this command to create model and migration file.

php artisan make:model Visitor -m

It will create two files –

Model – Visitor.php inside /app/Models folder
Migration file – xxx_create_visitors_table.php inside /database/migrations folder.

Open 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('visitors', function (Blueprint $table) {
            $table->id();
            $table->integer('click');
            $table->integer('viewer');
            $table->timestamps();
        });
    }

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

Run Migration

Back to terminal and run this command.

php artisan migrate

It will create visitors table inside database.

Next,

Seed Dummy Data in Application

Open application database and run this MySQL query to insert test data into visitors table.

--
-- Dumping data for table `visitors`
--

INSERT INTO `visitors` (`id`, `click`, `viewer`, `created_at`, `updated_at`) VALUES
(1, 25, 80, '2020-02-07 13:00:00', '2020-02-07 13:00:00'),
(2, 10, 45, '2021-02-11 13:00:00', '2021-02-11 13:00:00'),
(3, 18, 65, '2022-02-13 13:00:00', '2022-02-13 13:00:00'),
(4, 14, 57, '2023-02-21 13:00:00', '2023-02-21 13:00:00');

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 Total Click, Total Viewers according to Year wise.

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

Create Data Controller Class

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 Illuminate\Http\Request;
use App\Models\Visitor;
use Illuminate\Support\Facades\DB;
use Illuminate\View\View;

class GraphController extends Controller
{
    public function index(): View
    {
        $visitor = Visitor::select(
            DB::raw("year(created_at) as year"),
            DB::raw("SUM(click) as total_click"),
            DB::raw("SUM(viewer) as total_viewer")
        )
            ->orderBy(DB::raw("YEAR(created_at)"))
            ->groupBy(DB::raw("YEAR(created_at)"))
            ->get();

        $result[] = ['Year', 'Click', 'Viewer'];
        foreach ($visitor as $key => $value) {
            $result[++$key] = ["$value->year", (int)$value->total_click, (int)$value->total_viewer];
        }

        return view('line-chart')
            ->with('visitor', json_encode($result));
    }
}

Create Template File

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

Open file and write this complete code into it.

      var visitor = <?php echo $visitor; ?>;
      console.log(visitor);
      google.charts.load('current', {'packages':['corechart']});
      google.charts.setOnLoadCallback(drawChart);

      function drawChart() {
        var data = google.visualization.arrayToDataTable(visitor);
        var options = {
          title: 'Site Visitor Line Chart',
          curveType: 'function',
          legend: { position: 'bottom' }
        };
        var chart = new google.visualization.LineChart(document.getElementById('linechart'));
        chart.draw(data, options);
      }

    </script>

Add Route

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

//...

use App\Http\Controllers\GraphController;

//...

Route::get('line-chart', [GraphController::class, 'index']);

//...

Application Testing

Run this command into project terminal to start development server,

php artisan serve

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

Output
