labels 读取为 [object Object] 并且没有得到值 Livewire with Chart.js

Question

你好我真的需要帮助标签不显示在图表中，我正在使用 Laravel Livewire 和 Chart Js 标签显示 4 [object Object] 其中 4 个项目正确但不显示名称

我想要做的是将课程名称作为标签，getRandomnumber 是该表中值的数量

这是我的代码 Livewire 视图

<div>
<div class="justify-content-end text-end" style="right:0;">
    <select   style="width: 9rem;">
      
         <option value="{{ date('Y')}}">{{ date('Y')}}</option> 
             
    </select>
    
</div>
  <canvas id="myChart"></canvas>
</div>
@once
    @push('scripts')
        <script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
    @endpush
@endonce

@push('scripts')
    <script>
        const chart = new Chart(
            document.getElementById('myChart'), {
                type: 'bar',
                data: {
                    labels: @json($labels),
                    datasets: @json($dataset)
                },
                        options: {
            scales: {
                y: {
                beginAtZero: true
                }
            }
            }
        });
        Livewire.on('updateChart', data => {
            chart.data = data;
            chart.update();
        });
    </script>
@endpush

这是 Livewire 组件

<?php

namespace App\Http\Livewire\Chart;

use Livewire\Component;
use App\Models\Enrollment;
use Illuminate\Support\Facades\DB;
class ChartEnrollmentFirstYr extends Component
{


    public array $dataset = [];
    public array $labels = [];
    public function mount()
    {
        $this->labels[] = $this->getLabels();

        $this->dataset = [
            [
                'label' => 'Enrollees',
                'backgroundColor' => '#1d7e43',
               
                'data' => $this->getRandomData(),
            ],
        ];
        $labels = $this->getLabels();

        $dataset = [
            [
                'label' => 'Enrolless',
                'backgroundColor' => '#1d7e43',
               
                'data' => $this->getRandomData(),
            ],
        ];
        $this->emit('updateChart', [
            'datasets' => $dataset,
            'labels' => $labels,
        ]);
    
    }
    
    private function getLabels()
    {
        $labels = [];

        $alumni = DB::table('enrollments')         
        ->join('academic_programs', 'academic_programs.id','=','enrollments.degree_id')
        ->select('academic_programs.program_abbv as course, DB::raw(count(enrollments.id) as total)') 
        ->groupBy('academic_programs.program_abbv')
        ->orderBy('course')
        ->get();
        foreach ($alumni as $alu)
       {
        $labels[]= $alu;
       }
        return $labels;
    }

    private function getRandomData()
    {
        $data = [];
        $alumni = Enrollment::where('degree_id','!=',NULL)->orderBy('degree_id', 'ASC')->get();
        foreach ($alumni as $alu => $values )
       {
        $data[]= $values;
       }
        return $data;
    }
    public function render()
    {
        return view('livewire.chart.chart-enrollment-first-yr');
    }
