Step 2: Add/Create Migration Table

We need dynamic data for the pie chart example. So first, we have to create migration for the "product" table using the laravel php artisan command.

php artisan make:migration create_products_table --create=products

After running this command you will find the php file "database/migrations/".

<?php

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

class CreateProductsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    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();
        });
    }

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

After this, we need to run this migration by following the command in our terminal.

php artisan migrate

Step 3: Add Resource Route

Now add a route in the web.php file.

routes/web.php

<?php

use Illuminate\Support\Facades\Route;

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

Route::get('echarts', 'App\Http\Controllers\EchartController@echart');

Step 4: Create Controller And Model

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

php artisan make:controller EchartController

php artisan make:model Product

Step 5: Add Code In Model And Controller

Now, Add the below code in the Product Model file.

app\Models\Product.php

<?php

namespace App\Models;

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

class Product extends Model
{
    use HasFactory;

    protected $table = 'products';
    protected $guarded = [];
}

namespace App\Http\Controllers;
use App\Models\Product;
use Illuminate\Http\Request;

class EchartController extends Controller
{
    public function echart(Request $request)
    {
    	$fruit = Product::where('product_type','fruit')->get();
    	$veg = Product::where('product_type','vegitable')->get();
    	$grains = Product::where('product_type','grains')->get();
    	$fruit_count = count($fruit);    	
    	$veg_count = count($veg);
    	$grains_count = count($grains);
    	return view('echart',compact('fruit_count','veg_count','grains_count'));
    }
}

Step 6: Create Blade File

Now, we are creating an echart.blade.php file for viewing.
