带有highcharts（100％高度）的全屏面板引导程序

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.
