"""
The :mod:`.axis_artist` module implements custom artists to draw axis elements
(axis lines and labels, tick lines and labels, grid lines).

Axis lines and labels and tick lines and labels are managed by the `AxisArtist`
class; grid lines are managed by the `GridlinesCollection` class.

There is one `AxisArtist` per Axis; it can be accessed through
the ``axis`` dictionary of the parent Axes (which should be a
`mpl_toolkits.axislines.Axes`), e.g. ``ax.axis["bottom"]``.

Children of the AxisArtist are accessed as attributes: ``.line`` and ``.label``
for the axis line and label, ``.major_ticks``, ``.major_ticklabels``,
``.minor_ticks``, ``.minor_ticklabels`` for the tick lines and labels (e.g.
``ax.axis["bottom"].line``).

Children properties (colors, fonts, line widths, etc.) can be set using
setters, e.g. ::

  # Make the major ticks of the bottom axis red.
  ax.axis["bottom"].major_ticks.set_color("red")

However, things like the locations of ticks, and their ticklabels need to be
changed from the side of the grid_helper.

axis_direction
--------------

`AxisArtist`, `AxisLabel`, `TickLabels` have an *axis_direction* attribute,
which adjusts the location, angle, etc. The *axis_direction* must be one of
"left", "right", "bottom", "top", and follows the Matplotlib convention for
rectangular axis.

For example, for the *bottom* axis (the left and right is relative to the
direction of the increasing coordinate),

* ticklabels and axislabel are on the right
* ticklabels and axislabel have text angle of 0
* ticklabels are baseline, center-aligned
* axislabel is top, center-aligned

The text angles are actually relative to (90 + angle of the direction to the
ticklabel), which gives 0 for bottom axis.

=================== ====== ======== ====== ========
Property            left   bottom   right  top
=================== ====== ======== ====== ========
ticklabel location  left   right    right  left
axislabel location  left   right    right  left
ticklabel angle     90     0        -90    180
axislabel angle     180    0        0      180
ticklabel va        center baseline center baseline
axislabel va        center top      center bottom
ticklabel ha        right  center   right  center
axislabel ha        right  center   right  center
=================== ====== ======== ====== ========

Ticks are by default direct opposite side of the ticklabels. To make ticks to
the same side of the ticklabels, ::

  ax.axis["bottom"].major_ticks.set_tick_out(True)

The following attributes can be customized (use the ``set_xxx`` methods):

* `Ticks`: ticksize, tick_out
* `TickLabels`: pad
* `AxisLabel`: pad
