Fullscreen panel bootstrap with highcharts (100% height)

Question

I have several (bootstrap) panels where I would like to have the opportunity to show this fullscreen. Highcharts charts are present in these panels. The problem is that the height of the highcharts does not adapt when you are going in full screen mode, as is the case with the width. Is there a possibility to automatically adjust the scaling so that the ratio remains the same?

if this is not possible, I would like to have the graph aligned in the middle of the height.

CSS

.panel-actions {
  margin-top: -20px;
  margin-bottom: 0;
  text-align: right;
}

.panel-actions a {
  color: #333;
}

.panel-fullscreen {
  display: block;
  z-index: 9999;
  position: fixed;
  width: 100%;
  height: 100%;
  top: 0;
  right: 0;
  left: 0;
  bottom: 0;
  overflow: auto;
}

Hopefully someone can help me to solve this problem. Thank you in advance!!

As you can read in Highcharts documentation:

By default (when null) the height is calculated from the offset height of the containing element, or 400 pixels if the containing element's height is 0.

So, if you didn't specify the width value on parent element, then your chart has taken the 400px value and set it by default.

In order to make it fits as expected, you need to define any CSS height values on all containing elements. For example:

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