全屏面板引导与高图表（100% 高度）

Question

我有几个（引导）面板，我希望有机会在其中全屏显示。 Highcharts 图表出现在这些面板中。问题是当您进入全屏模式时，highcharts 的高度不适应，宽度也是如此。是否有可能自动调整比例以使比例保持不变？

如果这是不可能的，我想让图形在高度的中间对齐。

希望有人可以帮助我解决这个问题。提前谢谢你！

Answer 1

您可以在 Highcharts 文档中阅读：

默认情况下（null 时）高度是根据包含元素的偏移高度计算的，如果包含元素的高度为 0，则为 400 像素。

因此，如果您没有在父元素上指定 width 值，那么您的图表将采用 400px 值并默认设置它。

为了使其符合预期，您需要在所有包含元素上定义任何 CSS height 值。例如：

.col-lg-8.col-md-8.col-xs-8 {
  height: 100%
}
.panel-body {
 height: 94%
}
#container,
#container2 {
  height: 100%
}
