Laravel Charts - Sort by month

Good it is the first time that I use charts with Laravel and following a tutorial I have managed to do enough to account for months the income with the orders, but it does not put the bar in the month that it touches.

So I have it in the controller

$year = date('Y');
        $chart = new Ventachart;
        $chart->labels(['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);

        $totales = Order::select(\DB::raw('SUM(total) as total'))
                    ->whereYear('created_at', $year)
                    ->groupBy(\DB::raw("Month(created_at)"))
                    ->pluck('total');

  
        $chart->dataset("Pedidos: $year", 'bar', $totales)->options([
                    'fill' => 'true',
                    'borderColor' => '#51C1C0'
                ]);

Since I have purchases in two different months, he puts everything in the first and second bars. How do I get it to show me in the month it is playing?
