This issue is still the same in Octave 4.2.0.

Seems like the reasonable solution to me. Octave will be a superset of Matlab supporting xon and yon, but also zon. Nobody porting their code in the direction of Matlab -> Octave will have a problem.

Yeah, when I first wrote zoom, I think it did zoom on the three axes. But then when I tried to move in the direction of compatibility with the zoom object thing that Matlab has, and the zoom xon, zoom yon feature, I punted because it wasn't clear to me how to handle that. Matlab doesn't have zoom zon, or zoom xyon or zoom xyzon, etc. Should we allow those modes to be selected? Likewise for the pan function.

Confirmed.

I think it would be nice to fig bug #44323 by sizing the Z axis at the same time that the X and Y axes are changed. If that approach is adopted then I think it makes sense to expand zoom.m to cover the case of a third input for zoom.

help zoom gives:

Trying to set zoom factor for x & y, then x,y & z-axes:

The switch statement in zoom.m starting on L.101 clearly has no provisions for zoom factors in 3D, unlike the texinfo docs state.

(I hit this when investigating bug #44323 to check if I had overlooked the obvious)
