Follow-up Comment #34, bug #31305 (project octave):

I pushed a small changeset to fix "axis tight" so that it doesn't include the
hggroup's zdata.

http://hg.savannah.gnu.org/hgweb/octave/rev/2114867f2a50

The reason is that contour plots store the patches cdata in the hggroup's
zdata property.

To be entirely consistent with Matlab, contour/contourf should set zlim to
[-1, 1].
