sideview controls disabled

[Reimar Bauer]

On sideview the controls "zoom" "move" "home" etc. are all disabled and can't be used

[Joern Ungermann]

This is (partially) intended. Vertical zooming is implemented using the view options. Horizontal zooming could be implemented. But moving the plot doesn't make much sense, generally. I would say, we leave it as is, as the need for zooming into the vertical plots hasn't really come up so far. The implementation would also be non-trivial.
