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

Line chart represents the information in very graphical view which provides the complete idea about data. We will use Google charts to add Line 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

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

$ php artisan make:model Visitor -m

It will create two files –

Model – Visitor.php at /app/Models folder
Migration file – 2021_07_25_123805_create_visitors_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;

class CreateVisitorsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('visitors', function (Blueprint $table) {
            $table->id();
            $table->integer('click');
            $table->integer('viewer');
            $table->timestamps();
        });
    }

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

Open model file Visitor.php and write this complete code into it.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Visitor extends Model
{
    use HasFactory;
}

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 `visitors`
--

INSERT INTO `visitors` (`id`, `click`, `viewer`, `created_at`, `updated_at`) VALUES
(1, 25, 80, '2018-07-07 18:30:00', '2018-07-07 18:30:00'),
(2, 10, 45, '2019-07-11 18:30:00', '2019-07-11 18:30:00'),
(3, 18, 65, '2020-07-13 18:30:00', '2020-07-13 18:30:00'),
(4, 14, 57, '2021-07-21 18:30:00', '2021-07-21 18:30:00');

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 SampleController

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

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

<?php

namespace App\Http\Controllers;

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

class SampleController extends Controller
{
    public function googleLineChart()
    {
        $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('google-line-graph')
            ->with('visitor', json_encode($result));
    }
}

Create Blade Layout File

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

Open google-line-graph.blade.php and write this complete code into it.

<html>
  <head>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">
    
      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>
  </head>
  <body>
    <div id="linechart" style="width: 900px; height: 500px"></div>
  </body>
</html>

Create Route

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

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

//...

Route::get('google-line-chart', [SampleController::class, 'googleLineChart']);

Application Testing

Run this command into project terminal to start development server,

php artisan serve

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