I just added the long awaited zorder attribute to the Artist base
class in CVS, originally discussed here
http://sourceforge.net/mailarchive/message.php?msg_id=9363527.

There is a new example examples/zorder_demo.py that shows you how to
set the zorder.  I'll include it below.

It will be in the next release, probably early next week

    #!/usr/bin/env python
    """
    The default drawing order for axes is patches, lines, text.  This
    order is determined by the zorder attribute.  The following default
    are set

    Artist                      Z-order
    Patch / PatchCollection      1
    Line2D / LineCollection      2
    Text                         3

    You can change the order for individual artists by setting the zorder.

    In the fist subplot below, the lines are drawn above the patch
    collection from the scatter, which is the default.

    In the subplot below, the order is reversed
    """

    from pylab import *
    x = rand(20); y = rand(20)

    subplot(211)
    plot(x, y, 'r', lw=3)
    scatter(x,y,s=120)

    subplot(212)
    plot(x, y, 'r', zorder=1, lw=3)
    scatter(x,y,s=120, zorder=2)

    show()
