[Octave-bug-tracker] [bug #32311] text command differs between graphics_tookits

[Michael Godfrey]

Follow-up Comment #5, bug #32311 (project octave):

As an addition to my previous comment,
there are more problems with the positioning
of x,y, and z labels.  While experimenting
with the positioning of text() strings I
found that the x,y, and z label strings do not
maintain their correct positions relative to
the axes when axis() is used to change the axes.
Here is a simple example (with default clipping 'off')
but it also fails using a current tip with default
clipping 'on':

octave:1> plot(1:200)
octave:2> xlabel ('x label')
octave:3> ylabel ('y label')
octave:4> title('title')
octave:5> axis([50 100 50 150])
octave:6> axis([-50 300 -50 250])

For some reason the ylabel was moved correctly
but not the xlabel.  In a more complicated test
the zlabel ended up wrong.

It does not appear that default clipping 'off'
changes the behavior with respect to axis
and title strings.  But, I did notice
one behavior with default clipping off:  if one
shrinks the axes, the drawn data extends
outside the axes.  I have not checked Matlab
on this, but it could be that including the
drawn data outide the axes if clipping 'off'
is useful.

The definite error is not tying the axis labels to
the axes, whether clipping is 'on' or 'off'.
