Canvas js 图表在 Bootstrap 3 布局中没有正确响应

Question

我是 UI 开发人员，我正在使用 Bootstrap 3 和 Canvas Js 图表，如饼图、柱状图。我决定在每一行中放置两个图表，因为 desktop.And 它工作正常。但是当我调整浏览器大小时 window 它不会在移动设备中堆叠两个图表。相反，饼图消失了，只有第二个图表才可见。为什么会这样。

在桌面设备中

当我检查移动设备时。饼图消失了

代码在这里

Answer 1

Bootstrap 提供 grid-classes 以保持响应式设计。要明确设置平板电脑或移动设备的宽度，您需要添加平板电脑和移动设备的网格 classes 以及桌面 class.

在台式机、平板电脑和移动设备等多种设备中参考Bootstrap-Grid for more info. And here is a link to refer to examples of Bootstrap-Grid。

这是您的问题的工作代码。

var pieChartValues = [{
  y: 39.16,
  exploded: true,
  indexLabel: "Hello",
  color: "#1f77b4"
}, {
  y: 21.8,
  indexLabel: "Hi",
