动态更新ChartJS后的JavaScript

// 初始化图表
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 First dataset',
            backgroundColor: 'rgb(255, 99, 132)',
            borderColor: 'rgb(255, 99, 132)',
            data: [0, 10, 5, 2, 20, 30, 45]
        }]
    },
    options: {}
});

// 动态更新图表数据
function updateChart(newData) {
    myChart.data.datasets[0].data = newData;
    myChart.update();
}

// 假设这是新的数据
var newData = [15, 25, 30, 40, 50, 60, 70];
updateChart(newData);

function debounce(func, wait) {
    let timeout;
    return function(...args) {
        clearTimeout(timeout);
        timeout = setTimeout(() => func.apply(this, args), wait);
    };
}

const debouncedUpdateChart = debounce(updateChart, 100);

// 使用debouncedUpdateChart代替updateChart
