Abstract base class for the axis ticks, grid lines and labels.
Ticks mark a position on an Axis. They contain two lines as markers and
two labels; one each for the bottom and top positions (in case of an
`.XAxis`) or for the left and right positions (in case of a `.YAxis`).
Attributes
----------
tick1line : `~matplotlib.lines.Line2D`
The left/bottom tick marker.
tick2line : `~matplotlib.lines.Line2D`
The right/top tick marker.
gridline : `~matplotlib.lines.Line2D`
The grid line associated with the label position.
label1 : `~matplotlib.text.Text`
The left/bottom tick label.
label2 : `~matplotlib.text.Text`
The right/top tick label.

Base class for `.XAxis` and `.YAxis`.
Attributes
----------
isDefault_label : bool
axes : `~matplotlib.axes.Axes`
The `~.axes.Axes` to which the Axis belongs.
major : `~matplotlib.axis.Ticker`
Determines the major tick positions and their label format.
minor : `~matplotlib.axis.Ticker`
Determines the minor tick positions and their label format.
callbacks : `~matplotlib.cbook.CallbackRegistry`
label : `~matplotlib.text.Text`
The axis label.
labelpad : float
The distance between the axis label and the tick labels.
Defaults to :rc:`axes.labelpad` = 4.
offsetText : `~matplotlib.text.Text`
A `.Text` object containing the data offset of the ticks (if any).
pickradius : float
The acceptance radius for containment tests. See also `.Axis.contains`.
majorTicks : list of `.Tick`
The major ticks.
.. warning::
Ticks are not guaranteed to be persistent. Various operations
can create, delete and modify the Tick instances. There is an
imminent risk that changes to individual ticks will not
survive if you work on the figure further (including also
panning/zooming on a displayed figure).
Working on the individual ticks is a method of last resort.
Use `.set_tick_params` instead if possible.
minorTicks : list of `.Tick`
The minor ticks.

clear : bool, default: True
Whether to clear the Axis on creation. This is not required, e.g., when
creating an Axis as part of an Axes, as ``Axes.clear`` will call
``Axis.clear``.

Set the coordinates of the label.
By default, the x coordinate of the y label and the y coordinate of the
x label are determined by the tick label bounding boxes, but this can
lead to poor alignment of multiple labels if there are multiple Axes.
You can also specify the coordinate system of the label with the
transform. If None, the default coordinate system will be the axes
coordinate system: (0, 0) is bottom left, (0.5, 0.5) is center, etc.

Set this Axis' scale.
Parameters
----------
value : {"linear", "log", "symlog", "logit", ...} or `.ScaleBase`
The axis scale type to apply.
**kwargs
Different keyword arguments are accepted, depending on the scale.
See the respective class keyword arguments:
- `matplotlib.scale.LinearScale`
- `matplotlib.scale.LogScale`
- `matplotlib.scale.SymmetricalLogScale`
- `matplotlib.scale.LogitScale`
- `matplotlib.scale.FuncScale`
- `matplotlib.scale.AsinhScale`
Notes
-----
By default, Matplotlib supports the above-mentioned scales.
Additionally, custom scales may be registered using
`matplotlib.scale.register_scale`. These scales can then also
be used here.

Clear the axis.
This resets axis properties to their default values:
- the label
- the scale
- locators, formatters and ticks
- major and minor grid
- units
- registered callbacks

Display default minor ticks on the Axis, depending on the scale
(`~.axis.Axis.get_scale`).
Scales use specific minor locators:
- log: `~.LogLocator`
- symlog: `~.SymmetricalLogLocator`
- asinh: `~.AsinhLocator`
- logit: `~.LogitLocator`
- default: `~.AutoMinorLocator`
Displaying minor ticks may reduce performance; you may turn them off
using `minorticks_off()` if drawing speed is a problem.

Get appearance parameters for ticks, ticklabels, and gridlines.
.. versionadded:: 3.7
Parameters
----------
which : {'major', 'minor'}, default: 'major'
The group of ticks for which the parameters are retrieved.
Returns
-------
dict
Properties for styling tick elements added to the axis.
Notes
-----
This method returns the appearance parameters for styling *new*
elements added to this axis and may be different from the values
on current elements if they were modified directly by the user
(e.g., via ``set_*`` methods on individual tick objects).
Examples
--------
::
>>> ax.yaxis.set_tick_params(labelsize=30, labelcolor='red',
... direction='out', which='major')
>>> ax.yaxis.get_tick_params(which='major')
{'direction': 'out',
'left': True,
'right': False,
'labelleft': True,
'labelright': False,
'gridOn': False,
'labelsize': 30,
'labelcolor': 'red'}
>>> ax.yaxis.get_tick_params(which='minor')
{'left': True,
'right': False,
'labelleft': True,
'labelright': False,

Translate the kwargs supported by `.Axis.set_tick_params` to kwargs
supported by `.Tick._apply_params`.
In particular, this maps axis specific names like 'top', 'left'
to the generic tick1, tick2 logic of the axis. Additionally, there
are some other name translations.
Returns a new dict of translated kwargs.
Note: Use reverse=True to translate from those supported by
`.Tick._apply_params` back to those supported by
`.Axis.set_tick_params`.

Set the axis view limits. This method is for internal use; Matplotlib
users should typically use e.g. `~.Axes.set_xlim` or `~.Axes.set_ylim`.
If *ignore* is False (the default), this method will never reduce the
preexisting view limits, only expand them if *vmin* or *vmax* are not
within them. Moreover, the order of *vmin* and *vmax* does not matter;
the orientation of the axis will not change.
If *ignore* is True, the view limits will be set exactly to ``(vmin,

Set view limits.
This method is a helper for the Axes ``set_xlim``, ``set_ylim``, and
``set_zlim`` methods.
Parameters
----------
v0, v1 : float
The view limits. (Passing *v0* as a (low, high) pair is not
supported; normalization must occur in the Axes setters.)
emit : bool, default: True
Whether to notify observers of limit change.
auto : bool or None, default: False
Whether to turn on autoscaling of the x-axis. True turns on, False
turns off, None leaves unchanged.

Return a bounding box that encloses the axis. It only accounts
tick labels, axis label, and offsetText.
If *for_layout_only* is True, then the width of the label (if this
is an x-axis) or the height of the label (if this is a y-axis) is
collapsed to near zero. This allows tight/constrained_layout to ignore
too-long labels when doing their layout.

Whether to show the grid lines. If any *kwargs* are supplied, it
is assumed you want the grid on and *visible* will be set to True.
If *visible* is *None* and there are no *kwargs*, this toggles the
visibility of the lines.

The grid lines to apply the changes on.
**kwargs : `~matplotlib.lines.Line2D` properties
Define the line properties of the grid, e.g.::
grid(color='r', linestyle='-', linewidth=2)
NTz_First parameter to grid() is false, but line properties are supplied. The grid will be enabled.rG rH c S s i | ]\}}d |� �|�qS r r

Set the formatter of the major ticker.
In addition to a `~matplotlib.ticker.Formatter` instance,
this also accepts a ``str`` or function.
For a ``str`` a `~matplotlib.ticker.StrMethodFormatter` is used.
The field used for the value must be labeled ``'x'`` and the field used
for the position must be labeled ``'pos'``.
See the `~matplotlib.ticker.StrMethodFormatter` documentation for
more information.
For a function, a `~matplotlib.ticker.FuncFormatter` is used.
The function must take two inputs (a tick value ``x`` and a
position ``pos``), and return a string containing the corresponding
tick label.
See the `~matplotlib.ticker.FuncFormatter` documentation for
more information.

[*Discouraged*] Set this Axis' tick labels with list of string labels.
.. admonition:: Discouraged
The use of this method is discouraged, because of the dependency on
tick positions. In most cases, you'll want to use
``Axes.set_[x/y/z]ticks(positions, labels)`` or ``Axis.set_ticks``
instead.
If you are using this method, you should always fix the tick
positions before, e.g. by using `.Axis.set_ticks` or by explicitly
setting a `~.ticker.FixedLocator`. Otherwise, ticks are free to
move and the labels may end up in unexpected positions.
Parameters
----------
labels : sequence of str or of `.Text`\s
Texts for labeling each tick location in the sequence set by
`.Axis.set_ticks`; the number of labels must match the number of locations.
The labels are used as is, via a `.FixedFormatter` (without further
formatting).
minor : bool
If True, set minor ticks instead of major ticks.
fontdict : dict, optional
.. admonition:: Discouraged
The use of *fontdict* is discouraged. Parameters should be passed as
individual keyword arguments or using dictionary-unpacking
``set_ticklabels(..., **fontdict)``.
A dictionary controlling the appearance of the ticklabels.
The default *fontdict* is::
{'fontsize': rcParams['axes.titlesize'],
'fontweight': rcParams['axes.titleweight'],
'verticalalignment': 'baseline',
'horizontalalignment': loc}
**kwargs
Text properties.
.. warning::
This only sets the properties of the current ticks, which is
only sufficient for static plots.
Ticks are not guaranteed to be persistent. Various operations
can create, delete and modify the Tick instances. There is an
imminent risk that these settings can get lost if you work on
the figure further (including also panning/zooming on a
displayed figure).
Use `.set_tick_params` instead if possible.
Returns
-------
list of `.Text`\s
For each tick, includes ``tick.label1`` if it is visible, then
``tick.label2`` if it is visible, in that order.

Set this Axis' tick locations and optionally tick labels.
If necessary, the view limits of the Axis are expanded so that all
given ticks are visible.
Parameters
----------
ticks : 1D array-like
Array of tick locations (either floats or in axis units). The axis
`.Locator` is replaced by a `~.ticker.FixedLocator`.
Pass an empty list (``set_ticks([])``) to remove all ticks.
Some tick formatters will not label arbitrary tick positions;
e.g. log formatters only label decade ticks by default. In
such a case you can set a formatter explicitly on the axis
using `.Axis.set_major_formatter` or provide formatted
*labels* yourself.
labels : list of str, optional
Tick labels for each location in *ticks*; must have the same length as
*ticks*. If set, the labels are used as is, via a `.FixedFormatter`.
If not set, the labels are generated using the axis tick `.Formatter`.
minor : bool, default: False
If ``False``, set only the major ticks; if ``True``, only the minor ticks.
**kwargs
`.Text` properties for the labels. Using these is only allowed if
you pass *labels*. In other cases, please use `~.Axes.tick_params`.
Notes
-----
The mandatory expansion of the view limits is an intentional design
choice to prevent the surprise of a non-visible tick. If you need
other limits, you should set the limits explicitly after setting the
ticks.
Nz"Incorrect use of keyword argument zr. Keyword arguments other than 'minor' modify the text labels and can only be used if 'labels' are passed as well.rA r* )�next�iterrb r� r� )r_ r� r� r* ra Z first_key�resultr
