Wow! A guru at work... this solves all my current problems;
your insights and comments are most appreciated!
To return to my first post - matplotlib aims to make simple things
simple - I would argue that the way tickmarks are currently dealt
with is NOT simple & it would be great to see some simplifications
or additions to the interface to deal with the issues raised in this
thread (for example, by aligning their behaviour and properties to
other, similar, chart properties).
Thanks again,
Derek

[Again copying to matplotlib-users; maybe the main developers can
comment on whether these shortcomings in the getp/setp interface
should be fixed.]

I don't think that's directly supported. Here's a hacky way to do it:
lines = getp(gca(), 'xticklines')
toplines = [ l for l in lines if getp(l, 'ydata') == (1,) ]
setp(toplines, visible=False)
How I came up with this: I knew that I wanted to make some of the
xticklines invisible, so I looked at the list of line objects for
clues as to what differs between them. They seem to have xdata and
ydata properties, and ydata is (0,) for half of the lines and (1,)
for the other half, so it looks like it is the vertical position in
axis coordinates. (xdata seems to be in data coordinates.)

You're right, there is no obvious property to control this. Here's an
even hackier way to do this (and one that doesn't look very future-
proof):
for l in getp(gca(), 'xticklines'):
setp(l, 'marker', 5-getp(l, 'marker'))
The line objects have a marker property, which is 2 for some markers
and 3 for the others... so I guessed that one of them means upwards
and the other downwards, and checked this guess by flipping the
xtick.direction parameter and looking again. So subtracting the
marker from 5 flips the direction.
I wonder how this is done in Matlab?

I think you cannot do this with setp alone. Use the ylabel command:
ylabel('foo bar', fontsize=18)
