旋转木马：Y 轴，幻灯片更改时不显示数字
Carousel : Y-axis with numbers not displayed on slide change
我已将图表添加到轮播中，问题是图表不显示带有数字的 y 轴，它仅在加载时显示，在幻灯片更改时不显示，我尝试更改颜色、减小宽度，但没有出现根本。

即使在幻灯片更改时，图表也应显示 y 轴值。
无法在隐藏容器中绘制图表。
图表无法正确计算所有图表元素的位置。
需要等到图表显示后才能第一次绘制...
首先，只需要在页面首次显示时绘制第一个图表即可。
删除以下行（假设默认情况下首先显示 GoogleColChart_0）...
google.charts.setOnLoadCallback(function () { drawChart(80, 10, 'GoogleColChart_1'); });
google.charts.setOnLoadCallback(function () { drawChart(90, 15, 'GoogleColChart_2'); });
接下来，删除图表 <div> 元素内的 <script> 标签。
并将通过/失败计数添加为数据属性。
<div data-pass="70" data-fail="5" id='GoogleColChart_0' style='width:800; height:500;border-style:groove;border-width: 1px;'></div>
add 添加一个新的 <script> 标签作为正文结束前的最后一个标签 </body>,
监听轮播的 slid 事件。
当 slid 事件触发时，绘制显示的图表，
从数据属性传递值...
$('#myCarousel').on('slid.bs.carousel', function (sender) {
// draw chart that is shown
var container = $(sender.relatedTarget).find('div');
drawChart(container.data('pass'), container.data('fail'), container.prop('id'));
});
