我在 Bootstrap Carousel 中的 Chart Js 有问题，它不显示，因为图表未加载，它显示为width:0px and height:0px. 过去几个小时我一直在解决这个问题，希望你们能帮助我

这是您的代码的修订版本。我假设您使用的是 Chartjs 1.0.2。

HTML：（相同的 html 只是删除了 empty <div class="item"></div>）

图表：

function generateChart() {

    var LineChartCanvas = $("#line-chart-sample").get(0).getContext("2d");
    var LineChartSample = new Chart(LineChartCanvas);

    var LineChartSampleData = {
    labels: ["Q1", "Q2", "Q3", "Q4", "Q5", "Q6","Q7"],
    datasets: [
        {
        label: "Sales 1",
        fillColor: "transparent",
        strokeColor: "rgba(220,220,220,1)",
        pointColor: "rgba(220,220,220,1)",
        pointStrokeColor: "#fff",
        pointHighlightFill: "#fff",
        pointHighlightStroke: "rgba(220,220,220,1)",
        data: [11, 12, 13, 14, 15, 16, 17]
        }, 
        {
        label: "Sales 5",
        fillColor: "transparent",
        strokeColor: "rgba(236, 80, 80,1)",
        pointColor: "rgba(236, 80, 80,1)",
        pointStrokeColor: "#fff",
        pointHighlightFill: "#fff",
        pointHighlightStroke: "rgba(236, 80, 80,1)",
        data: [15, 21, 35, 42, 33, 33, 81]
        }
        ]
    };
    LineChartSample.Line(LineChartSampleData);

    //Bar Chart Sample        
    var BarChartCanvas = $("#bar-chart-sample").get(0).getContext("2d");
    var BarChartSample = new Chart(BarChartCanvas);

    var BarChartSampleData = {
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [
            {
            label: "My First dataset",
            fillColor: "rgba(220,220,220,0.5)",
            strokeColor: "rgba(220,220,220,0.8)",
            highlightFill: "rgba(220,220,220,0.75)",
            highlightStroke: "rgba(220,220,220,1)",
            data: [65, 59, 80, 81, 56, 55, 40]
            },
            {
            label: "My Second dataset",
            fillColor: "rgba(151,187,205,0.5)",
            strokeColor: "rgba(151,187,205,0.8)",
            highlightFill: "rgba(151,187,205,0.75)",
            highlightStroke: "rgba(151,187,205,1)",
            data: [28, 48, 40, 19, 86, 27, 90]
            }
        ]
    };
    BarChartSample.Bar(BarChartSampleData);
};
generateChart();

现在，由于您使用的是引导轮播，因此只显示具有active类的项目。Chartjs 无法为隐藏的画布元素生成图表。

一种解决方法是在触发事件后生成图表。

像这样：

function resetChart() {
    //Reset chart data 
    $('canvas').remove();
    $('.item2').prepend('<canvas id="line-chart-sample" height="80"></canvas>');
    $('.item1').prepend('<canvas id="bar-chart-sample" height="80"></canvas>');

    generateChart();
}

$(document).on('click', '.carousel-control', function () {
    resetChart();
});

现在我不确定这是否是解决此问题的最佳方法。但它有效。

更新：

幻灯片动画

$('#myCarousel').carousel({
    interval: 2000,
    cycle: true
});

幻灯片方法完成转换后调用函数

$('#myCarousel').on('slid.bs.carousel', function () {
    resetChart();
})

在这里看到它的工作： JSfiddle Demo
