=============================
Custom spines with axisartist
=============================

This example showcases the use of :mod:`.axisartist` to draw spines at custom
positions (here, at ``y = 0``).

Note, however, that it is simpler to achieve this effect using standard
`.Spine` methods, as demonstrated in
:doc:`/gallery/spines/centered_spines_with_arrows`.

    # To construct Axes of two different classes, we need to use gridspec (or
    # MATLAB-style add_subplot calls).

    # additional axis, named "xzero" (the y=0 axis) and "yzero" (the x=0 axis).
