是否可以在chartjs中将多个图表组合到一个画布中？

<canvas id="myChart"></canvas>

var ctx = document.getElementById('myChart').getContext('2d');

var chart1 = new Chart(ctx, {
    type: 'line',
    data: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [{
            label: 'Dataset 1',
            data: [10, 20, 30, 40, 50, 60, 70],
            borderColor: 'red',
            fill: false
        }]
    }
});

var chart2 = new Chart(ctx, {
    type: 'line',
    data: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [{
            label: 'Dataset 2',
            data: [70, 60, 50, 40, 30, 20, 10],
            borderColor: 'blue',
            fill: false
        }]
    }
});
