// 引入Chart.js库
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>

// 创建图表对象
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [{
            label: 'Sales',
            data: [12, 19, 3, 5, 2, 3, 10],
            backgroundColor: 'rgba(75, 192, 192, 0.2)',
            borderColor: 'rgba(75, 192, 192, 1)',
            borderWidth: 1
        }]
    },
    options: {
        scales: {
            x: {
                beginAtZero: true
            }
        }
    }
});

// 修改x轴标签
myChart.data.labels = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul'];

// 更新图表
myChart.update();
