Tried this also:

octave:17> axis([-8000,8000,0,8000,-8000,8000],"square")
octave:18> hold("on") 
octave:19> plot3 ([0 8000]', [0 8000]', [0 8000]', "r")
octave:20> set (gca (), "position", [0.13000 -0.05000 0.77500 1.08000]);

This works on my Octave version 3.2.3 (just tried it)

May I just check that you noticed that your axes do not have a cubic ratio.
Did you mean to write

axis([-8000,8000,-8000,8000,-8000,8000],"square")?

With regard to your other question

>Is there a possibility to make the ellipsoid transparent, so that these 3
Lines are visible?

the command that you need is 

hidden()

This may be used as above; under these circumstances, it will toggle between
'off' and 'on', or you could specify explicitly eg

hidden('off')

Hope this works.
