You cannot rotate the entire figure. Figures are graphic windows -- everything including the standard window controls to close or minimize or maximize the window.
Back in the day... Before OpenGL existed, SGI (a once important company that created OpenGL) had its own graphics language named GL, and the window manager they used was based on DisplayPostscript . DisplayPostscript literally could rotate graphic windows -- and graphic windows for it were not restricted to being rectangular either. It was even possible to create disconnected regions...
Rectangular graphic windows might perhaps have simplified programming, but I still think computing lost something went it did not take up DisplayPostscript or similar equivalent.

If you need the objects to rotate but the axes to stay fixed, then you should create a hgtransform() group and set its Matrix property, likely with a transform created using makehgtform()
If you need the axes to rotate as well, then instead you should manipulate the camera properties; see https://www.mathworks.com/help/matlab/creating_plots/low-level-camera-properties.html -- or perhaps just using view() to set a matrix might work for your purposes.
