Follow-up Comment #14, bug #50466 (project octave):

We haven't announced hgtransform because it is incomplete.  At the very least,
it needs to have the documentation finished.

For text objects, as I understand it, not only do the coordinates of the text
object have to change, but so does the "rotation" property.  Since Octave is
not doing that, it issues a warning.

Can you provide the source code for the transform which isn't working?

A simple test of a rotation seems okay.

hl = line ();
ht = hgtransform ();
set (hl, 'parent', ht);
xfrm = get (ht, 'matrix')
xfrm(1:2,1:2) = [cos(pi/2), sin(pi/2); -sin(pi/2), cos(pi/2)]
set (ht, 'matrix', xfrm);
