How To Create Dynamic Line Chart In Laravel 9

In this article, we will see how to create a dynamic line chart in laravel 9. A dynamic line chart or line plot or line graph or curve chart is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields.

So, let's see line chart example in laravel 9, line chart in laravel 9, dynamic line chart example in laravel 9, line chart in PHP, laravel 9 chart js tutorial.

For the creation of a dynamic line chart example, you need to create a route, controller, blade file, and database. So, if you follow the tutorial step by step then definitely you will get output.

 

In this step, we will create the laravel 9 project using the below command.

composer create-project --prefer-dist laravel/laravel linechart

 

 

After that, we are getting dynamic data for line chart example. So, first, we need to create migration for the "product" table using the below command.

php artisan make:migration create_products_table --create=products

After running this command you will find the PHP file on location "database/migrations/". And in this file add the below code.

<?php

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

class CreateProductsTable extends Migration
{
    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('name')->nullable();
            $table->integer('price')->nullable();
            $table->integer('year')->nullable();
            $table->string('product_type')->nullable();
            $table->timestamps();
        });
    }
    public function down()
    {
        Schema::dropIfExists('products');
    }
}

After these changes we need to run this migration by the following command in our terminal:

php artisan migrate

 

 

Now, add a route in the routes/web.php file.

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\LinechartController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('line-chart', [LinechartController::class,'linechart']);

 

After adding the route, we need to create a new controller and model for the line chart example. So, type the below command for creating a controller.

php artisan make:controller LinechartController

php artisan make:model Product

 

 

Add below code in your app\Http\Controllers\LinechartController.php file.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Product;

class LinechartController extends Controller
{
    public function linechart(Request $request)
    {
    	$phone_count_20 = Product::where('product_type','Phone')->where('year','2020')->get()->count();
    	$phone_count_21 = Product::where('product_type','Phone')->where('year','2021')->get()->count();
    	$phone_count_22 = Product::where('product_type','Phone')->where('year','2022')->get()->count();
    	
    	$laptop_count_20 = Product::where('product_type','Laptop')->where('year','2020')->get()->count();
    	$laptop_count_21 = Product::where('product_type','Laptop')->where('year','2021')->get()->count();
    	$laptop_count_22 = Product::where('product_type','Laptop')->where('year','2022')->get()->count();

    	$desktop_count_20 = Product::where('product_type','Desktop')->where('year','2020')->get()->count();
    	$desktop_count_21 = Product::where('product_type','Desktop')->where('year','2021')->get()->count();
    	$desktop_count_22 = Product::where('product_type','Desktop')->where('year','2022')->get()->count();    	
    	
    	return view('linechart',compact('phone_count_20','phone_count_21','phone_count_22','laptop_count_20','laptop_count_21','laptop_count_22','desktop_count_20','desktop_count_21','desktop_count_22'));
    }
}

 

In this step, we are creating a linechart.blade.php file for view.
