我可以偏移chart.js堆叠条形图中的条形图吗？

var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['Category 1', 'Category 2', 'Category 3'],
        datasets: [{
            label: 'Dataset 1',
            data: [10, 20, 30],
            backgroundColor: 'rgba(255, 99, 132, 0.5)',
            borderColor: 'rgba(255, 99, 132, 1)',
            borderWidth: 1,
            stack: 'Stack 1'
        }, {
            label: 'Dataset 2',
            data: [20, 30, 40],
            backgroundColor: 'rgba(54, 162, 235, 0.5)',
            borderColor: 'rgba(54, 162, 235, 1)',
            borderWidth: 1,
            stack: 'Stack 1'
        }]
    },
    options: {
        scales: {
            x: {
                stacked: true,
                barPercentage: 0.7, // 调整条形图宽度
                categoryPercentage: 0.9 // 调整类别间距
            },
            y: {
                stacked: true
            }
        }
    }
});
