我在图表上工作，但是只输出一个用户的数据

    $data = collect([]); // Could also be an array

        for ($months_backwards = 2; $months_backwards >= 0; $months_backwards--) {
            // Could also be an array_push if using an array rather than a collection.
            $actMonth = Carbon::now();
            $data->push(Slaughter::whereDate('dateOfDisplacement',$actMonth->subMonth($months_backwards))->count());
        }

        $chart1 = new AnimalChart;
        $chart1->labels(['2 months ago','Last Month','Current Month']);
        $chart1->dataset('Animal Slaughtered','line',$data)
            ->color($borderColors)
            ->backgroundcolor($fillColors);
 return view('admin.index',compact(['users','chart','chart1','chart2']));
    }

这是输出所有被宰杀的动物，但仅输出给第一个农场，而不是全部。换句话说，它仅输出动物farm_id为1（并非全部）的屠宰详细信息
