你能在Chart.js中为不同的轴设置不同的颜色吗？

var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'line',
    data: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [{
            label: 'My Dataset',
            data: [10, 20, 30, 40, 50, 60, 70]
        }]
    },
    options: {
        scales: {
            x: {
                ticks: {
                    fontColor: 'red'
                }
            },
            y: {
                ticks: {
                    fontColor: 'blue'
                }
            }
        }
    }
});
