Thanks Ben, I appreciate your comments but I'm not sure that's the case.

Please see the output I've just captured:

Octave in any directory

=====================================================

Plot ONLY works if I start Octave from the ../m/plot/ directory which is
crazy! The colororder property is not valid if I start Octave from anywhere
else.
