[Octave-bug-tracker] [bug #44323] Zooming in 3D plots works on XY plane rather than projection plane

[Philip Nienhuis]

Follow-up Comment #2, bug #44323 (project octave):

I'm sorry I wasn't clear enough. I'll try again.

With "projection plane" I mean this: any 3D-object is obviously projected to a
2D plane when drawn on a screen.

I've attached 3 pics of the command
plot3 ([0 1], [0 1], [0 1], "r", "linewidth", 3)

In the first all three axes (XYZ) extend from 0-1.
In the second (zoomed out) plot, only the X- and Y-axes have been zoomed out
(larger range limits), the Z-axis limits are still [0 1].
Same goes for the 3rd pic (zoomed in), where the X_ and Y-axis are zoomed in
but the Z-axis limits again remain to be [0 1].

It may be even easier to simply zoom out on the 3D-plot made by the sombrero
command. The plot will be stretched in the Z-direction, as the Z-axis limits
remain to be [0 1].

My conclusion is that zooming in and out only works on the X and Y axes, but
ignores the Z-axis.

As stated in the original report, Matlab zooms in/out on all 3 axes for 3D
graphs.

I think this ML-incompatible behavior has been there for a very long time.
