Step 1: Install Laravel

Type the following command in the terminal.

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

Step 2: Add/Create Migration Table

We need dynamic data for the bar chart example. So first, we have to create migration for the "product" table using laravel PHP artisan command, So, the first type is 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('barchart', 'BarchartController@barchart');

php artisan make:controller BarchartController

php artisan make:model Product

Step 5: Add Code In Controller

In this step, we will add the below code in the App\Http\Controllers\BarchartController path.

<?php

namespace App\Http\Controllers;

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

class BarchartController extends Controller
{
    public function barchart(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('barchart',compact('fruit_count','veg_count','grains_count'));
    }
}
