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. So, first type the below command.

php artisan make:migration create_products_table --create=products

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

<?php

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

class CreateProductTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('product', 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('product');
    }
}

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

php artisan migrate

Route::get('echarts', 'EchartController@echart');

Step 4: Create Controller And Model

After adding the route we need to create a new controller and model so type the below command to create a controller.

php artisan make:controller EchartController

php artisan make:model Product

Step 5: Add Code In Controller

Add the below code in the App\Http\Controllers\EchartController path.

<?php

namespace App\Http\Controllers;
use App\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'));
    }
}
