Sorry; that is ten bugs. Initially I only saw the three in my email notification.

Three bugs fixed with one cset, not bad.
Thanks Rik.

Fixed on the development branch in this cset: https://hg.savannah.gnu.org/hgweb/octave/rev/a7dfb00d5bf5.

This will be a part of the Octave 6.1 release.  To access the fix sooner download axis.m from the Mercurial development branch and replace your local copy.

Closing report.

For the truncation of upper and lower parts of the picture I entered bug #55574.

Steps to reproduce:

pic = imread ("cea.tif"); ## file is attached
hr = imshow (pic, "xdata", [-28493.16678, 2358.21162], "ydata", [4224973.14326, 4255884.54380]);  ## more or less square plot
axis equal  ; ## plot disappears

In 4.4.1 this works more or less as I expect, be it that the lower part of the picture gets truncated after "axis equal" and a rectangular plot is shown (looks like another bug BTW).

Interchanging the vector arguments for "xdata" and "ydata" in the call to imshow makes it work again in 5.0.1, incl. the truncated plot bottom.

AFAICS it happens in axis.m -> __axis__ at L.227 when the "plotboxaspectratio" property is set.
