[Octave-bug-tracker] [bug #51938] Contour lines of meshc disappear when calling axis

[Dan Sebald]

Follow-up Comment #8, bug #51938 (project octave):

I may have found the property I was looking for.  The "handlevisibility" seems
to affect whether or not the object is included in the axes data elements for
auto-ranging.  Attached is a new patch in which the contour placement does not
alter the zlim settings.  I think this is more along the lines of what people
are expecting.  However, often, as in the case of gnuplot, the contour plane
is technically in the z-range but is an extended area having its own parameter
controlling the percentage of space to add.  Note, however, that Octave as it
stands can't do that because this line of code:


    [~, htmp2] = __contour__ (hax, zmin, varargin{:});


is using zmin.
