如何在Chartisan中制作堆叠条形图

use Chartisan\PHP\Chartisan;
use ConsoleTVs\Charts\BaseChart;

class StackedBarChart extends BaseChart implements Chartisan
{
    public function name(): string
    {
        return 'Stacked Bar Chart';
    }

    public function labels(): array
    {
        return ['Label 1', 'Label 2', 'Label 3'];
    }

    public function dataset(): array
    {
        return [
            [
                'name' => 'Dataset 1',
                'values' => [10, 20, 30],
            ],
            [
                'name' => 'Dataset 2',
                'values' => [15, 25, 35],
            ],
        ];
    }

    public function options(): array
    {
        return [
            'stacked' => true,
        ];
    }
}

use App\Charts\StackedBarChart;

Route::get('/chart', function () {
    $chart = new StackedBarChart;
    return $chart->render();
});
