@nrjank: Yes, this feature request is still valid.  Octave is Matlab-compatible here, i.e., we also produce horizontal labels for the x-axis and y-axis.  Michael's request, and a feature above and beyond Matlab, would be to rotate these labels to be parallel to the axes.

Given that our Qt backend now supports rotation of text objects this should be possible.  But, someone has to be motivated enough to code it.  And as jwe indicated, he would like this to be configurable so that we don't get complaints from Matlab users that the plot is different.

Is this old report still valid?

Testing with Octave 8.4.0 (and 9.0.1) and Matlab 2023b, I get the attached images when running one of Octave's demo scripts for mesh.  Other than matlab putting "" around it's lables, and maybe some position differences, both programs produce all horizontal/vertical labels.

Marking as need info in case I'm missing some other use case, but perhaps this old report can be closed.  As Rik mentioned in comment #10 the ability to rotate axis labels is being addressed by other reports.

Also see bug #62882 where I provided a patch for implementing xticklabelrotation().  It's not perfect, but should be doable now.

FYI bug #33118 has been closed.
According to comment #7 this could be simple to implement.

bug #33118 still exists in Octave 4.2.0, but only for fltk and qt toolkits.

Adding a dependency on bug #33118 which is the ability to have arbitrary rotations in FLTK.  If that is fixed this would be fairly simple to implement.

This will be hard for the FLTK backend which only supports text rotation in 90 degree increments.

The gnuplot backend supports arbitrary rotation, but unfortunately it seems to work only for text objects and not for xlabels or ylabels.

Ok to mark it as request/wishlist.

I'm not opposed to allowing the behavior you want, but I think it should probably be configurable.  I also have no idea how to make the change.  OK to mark as a feature request/wishlist item?

Sorry to say that this is also how Matlab does it.

While that does somewhat reduce the interest in
fixing it, I still think that most users would
prefer the x and y labels to be parallel to the
axes (as is the zlabel).  And, I do not think
that this should be decided by compatibility.

I see the same behvior with gnuplot.

Using mesh() and possibly other 3D plots
the xlabel and ylabel text is horizontal,
not parallel to the respective axes.

Is this a known behavior?
The appropriate orientation is parallel to
each axis.
