Equivalent to GnuPlot's nomirror?

I'm no GnuPlot user, but try this:

    > ax = gca() ax.yaxis.tick_left() ax.xaxis.tick_bottom()

Yep, that is better than my suggestion. Thanks. It would be nice to
draw the edges with lines rather than a rectangle so we can turn them
on and off selectively as well (an detach them...)
