Since "handle graphics" is a MathWorks trademark, please avoid using
it to describe the plotting system in Octave.

No, positioning doesn't work in the current Octave plotting code.

I've said several times now that the current code is just a temporary
solution.  The old system was becoming unmanageable and the current
code was my way to start digging out of the mess.  We all know it is
not perfect.  But it is a start at something better.  Have some
patience.
