如何在chartjs中单独更改条宽？

var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['A', 'B', 'C'],
        datasets: [{
            label: 'Data',
            data: [10, 20, 30],
            backgroundColor: 'rgba(0, 123, 255, 0.5)',
            borderColor: 'rgba(0, 123, 255, 1)',
            borderWidth: 1
        }]
    },
    options: {
        scales: {
            x: {
                grid: {
                    display: false
                }
            },
            y: {
                beginAtZero: true
            }
        },
        plugins: {
            legend: {
                display: false
            }
        },
        layout: {
            padding: {
                left: 10,
                right: 10,
                top: 10,
                bottom: 10
            }
        },
        indexAxis: 'y',
        barPercentage: 0.5, // 设置柱状图的条宽
        categoryPercentage: 0.8 // 设置柱状图的宽度相对于整个图表区域的比例
    }
});
