"""
|
||
|
|
The rcsetup module contains the default values and the validation code for
|
||
|
|
customization using matplotlib's rc settings.
|
||
|
|
|
||
|
|
Each rc setting is assigned a default value and a function used to validate
|
||
|
|
any attempted changes to that setting. The default values and validation
|
||
|
|
functions are defined in the rcsetup module, and are used to construct the
|
||
|
|
rcParams global object which stores the settings and is referenced throughout
|
||
|
|
matplotlib.
|
||
|
|
|
||
|
|
These default values should be consistent with the default matplotlibrc file
|
||
|
|
that actually reflects the values given here. Any additions or deletions to the
|
||
|
|
parameter set listed here should also be visited to the
|
||
|
|
:file:`matplotlibrc.template` in matplotlib's root source directory.

"""
|

|
|
Creates a `~cycler.Cycler` object much like :func:`cycler.cycler`,
|
||
|
|
but includes input validation.
|
||
|
|
|
||
|
|
Call signatures::
|
||
|
|
|

|
|
cycler(cycler)
|

cycler(label=values[, label2=values2[, ...]])
|

|
cycler(label, values)
|
||
|
|
|
||
|
|
Form 1 copies a given `~cycler.Cycler` object.
|
||
|
|
|
||
|
|
Form 2 creates a `~cycler.Cycler` which cycles over one or more
|
||
|
|
properties simultaneously. If multiple properties are given, their
|
||
|
|
value lists must have the same length.
|
||
|
|
|
||
|
|
Form 3 creates a `~cycler.Cycler` for a single property. This form
|
||
|
|
exists for compatibility with the original cycler. Its use is
|
||
|
|
discouraged in favor of the kwarg form, i.e. ``cycler(label=values)``.

|
|

Parameters
|
||
|
|
----------
|
||
|
|
cycler : Cycler
|
||
|
|
Copy constructor for Cycler.
|
||
|
|
|
||
|
|
label : str
|
||
|
|
The property key. Must be a valid `.Artist` property.
|
||
|
|
For example, 'color' or 'linestyle'. Aliases are allowed,
|
||
|
|
such as 'c' for 'color' and 'lw' for 'linewidth'.
|
||
|
|
|
||
|
|
values : iterable
|
||
|
|
Finite-length iterable of the property values. These values
|
||
|
|
are validated and will raise a ValueError if invalid.
|
||
|
|
|
||
|
|
Returns
|
||
|
|
-------
|
||
|
|
cycler : Cycler
|
||
|
|
A new :class:`~cycler.Cycler` for the given properties.
|
||
|
|
|
||
|
|
Examples
|
||
|
|
--------

Creating a cycler for a single property:

||
|
|
>>> c = cycler(color=['red', 'green', 'blue'])
|
||
|
|
|
||
|
|
Creating a cycler for simultaneously cycling over multiple properties
|
||
|
|
(e.g. red circle, green plus, blue cross):
|
||
|
|
|
||
|
|
