rcsetup

matplotlib.rcsetup

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 matplotlibrc.template in matplotlib's root source directory.

class matplotlib.rcsetup.ValidateInStrings(key, valid, ignorecase=False)[source]

Bases: object

valid is a list of legal strings

class matplotlib.rcsetup.ValidateInterval(vmin, vmax, closedmin=True, closedmax=True)[source]

Bases: object

Value must be in interval

matplotlib.rcsetup.cycler(*args, **kwargs)[source]

Creates a Cycler object much like cycler.cycler(), but includes input validation.

Call signatures:

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

Form 1 copies a given Cycler object.

Form 2 creates a 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 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 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):

>>> c = cycler(color=['red', 'green', 'blue'],
...            marker=['o', '+', 'x'])
