Equivalent to GnuPlot's nomirror?

Does Matplotlib support something equivalent to GnuPlot's

    > nomirror functionality where the x and y axes are only
    > displayed on the bottom and left of the graph and are not
    > 'mirrored' to the top and right?

Not yet, but it's on the goals page at
http://matplotlib.sf.net/goals.html under the "Axis autoranging and
tick customization" section

When "Detachable axis from main axes box and customizable tickline
locations" are implemented, your request will be as well. The problem
is that the edge of the axes is currently drawn as the edge of a
rectangle, not four separate lines. You can, however, turn off the
ticks on the right and top sides

for tick in ax.xaxis.get_major_ticks():
    tick.tick2On = False

See http://matplotlib.sf.net/matplotlib.axis.html for more information
on customizing the axis.

Have fun!
