[Octave-bug-tracker] [bug #40005] set (ax, "ylim") incorrectly scales axis from deep within listener hierarchy

[Rik]

Follow-up Comment #2, bug #40005 (project octave):

The problem is still there.  I've re-written the example so that the problem
is evident.


##########################################################################
## FIXME: Setting xlim or ylim from within a listener callback
##        causes the axis to change size rather than change limits.
##        Workaround it by jiggling the position property which forces
##        a redraw of the axis object.
##
## To see the problem:
## Comment out the 5 lines below the comment box which jiggle position
## 
## Now run the the following code:
##   clear -f
##   clf; contour (peaks ()); colorbar (); 
##   caxis ([0 5]);
## Up to this point everything is fine.
##   caxis ("auto");
## Now colorbar will be badly sized.
##
## The problem line is
##   set (hiax, "ylim", cext) 
##
## The issue seems to be that the axes object is redrawn to the wrong size
## and then is marked as clean so that further internal calls which set the
## correct size do not cause the object to be refreshed.

I added the instructions to colorbar.m
