设置全局参数——定制matplotlib（部分翻译）

关键词：style，rcParams，rc

全局参数的设置——

###使用style包：

style包能让你很轻松的切花绘图的类型，预先在matplotlib中定义好了许多style类型供选择，使用的方式如下

import matplotlib.pyplot as plt
plt.style.use('ggplot')#ggplot就是一种style的名称

获得所有提供的styles的方法如下:

style_list = print(plt.style.available)

输出的所有类型如下(使用的时候可以如下选择）：

['seaborn-paper',
 'seaborn-dark-palette',
 'seaborn-notebook',
 'dark_background',
 'seaborn-whitegrid',
 'seaborn-talk',
 'fivethirtyeight',
 'ggplot',
 'seaborn-ticks',
 'grayscale',
 'bmh',
 'seaborn-dark',
 'seaborn-poster',
 'seaborn-deep',
 'seaborn-darkgrid',
 'classic',
 'seaborn-white',
 'seaborn-colorblind',
 'seaborn-bright',
 'seaborn-pastel',
 'seaborn-muted']

定义属于自己的属性

你可以定义属于自己风格的style，具体的定义方式请查看源文档。

复合风格

plt.style.use(['bmh','dark_background'])

#plt.style.use(style)-->其中style类型有style : str, dict, or list

类型	介绍
str	The name of a style or a path/URL to a style file. For a list of available style names, see style.available.
dict	Dictionary with valid key/value pairs formatplotlib.rcParams.
list	A list of style specifiers (str or dict) applied from first to last in the list.

暂时风格

不做介绍

rcParams模块（十分常用）

动态rc设定

我们可以动态的改变已经在style中预设好的rc参数，所有的rc设置都被存储在一个类似字典的变量中——matplotlib.rcParams，这是一个全局包，工作方式有如下几种：

#方式一
import matplotlib as mpl
mpl.rcParams['lines.linewidth'] = 2 #类字典格式，键值对
mpl.rcParams['lines.color'] = 'r'

#方式二
mpl.rc('lines',linewidth = 2,color = 'r')

#方式三
font = {
    	'family' : 'monospace',
        'weight' : 'bold',
        'size'   : 'larger'
		}
mpl.rc('font',**font)

NOTICE:

#关于rc的解释
matplotlib.rc(group, **kwargs)
#即rc接受一个Group,这个Group就是类型，比如'font','lines','text'等等
#后面的可以直接接受单个的键值对，也可以直接接收字典

所有Group类型包含的属性见英文原文最后的matplotlibrc文档的示例

Customizing matplotlib

Using style sheets

The style package adds support for easy-to-switch plotting “styles” with the same parameters as a matplotlibrc file (which is read at startup to configure matplotlib).

There are a number of pre-defined styles provided by matplotlib. For example, there’s a pre-defined style called “ggplot”, which emulates the aesthetics of ggplot (a popular plotting package for R). To use this style, just add:

>>> import matplotlib.pyplot as plt
>>> plt.style.use('ggplot')

To list all available styles, use:

>>> print(plt.style.available)

Defining your own style

You can create custom styles and use them by calling style.use with the path or URL to the style sheet. Additionally, if you add your <style-name>.mplstyle file to mpl_configdir/stylelib, you can reuse your custom style sheet with a call to style.use(<style-name>). By default mpl_configdir should be ~/.config/matplotlib, but you can check where yours is with matplotlib.get_configdir(); you may need to create this directory. You also can change the directory where matplotlib looks for the stylelib/ folder by setting the MPLCONFIGDIR environment variable, see matplotlib configuration and cache directory locations.

Note that a custom style sheet in mpl_configdir/stylelib will override a style sheet defined by matplotlib if the styles have the same name.

For example, you might want to create mpl_configdir/stylelib/presentation.mplstyle with the following:

axes.titlesize : 24
axes.labelsize : 20
lines.linewidth : 3
lines.markersize : 10
xtick.labelsize : 16
ytick.labelsize : 16

Then, when you want to adapt a plot designed for a paper to one that looks good in a presentation, you can just add:

>>> import matplotlib.pyplot as plt
>>> plt.style.use('presentation')

Composing styles

Style sheets are designed to be composed together. So you can have a style sheet that customizes colors and a separate style sheet that alters element sizes for presentations. These styles can easily be combined by passing a list of styles:

>>> import matplotlib.pyplot as plt
>>> plt.style.use(['dark_background', 'presentation'])

ote that styles further to the right will overwrite values that are already defined by styles on the left.

Temporary styling

If you only want to use a style for a specific block of code but don’t want to change the global styling, the style package provides a context manager for limiting your changes to a specific scope. To isolate your styling changes, you can write something like the following:

>>> import numpy as np
>>> import matplotlib.pyplot as plt
>>>
>>> with plt.style.context(('dark_background')):
>>>     plt.plot(np.sin(np.linspace(0, 2 * np.pi)), 'r-o')
>>>
>>> # Some plotting code with the default style
>>>
>>> plt.show()

matplotlib rcParams

Dynamic rc settings

You can also dynamically change the default rc settings in a python script or interactively from the python shell. All of the rc settings are stored in a dictionary-like variable called matplotlib.rcParams, which is global to the matplotlib package. rcParams can be modified directly, for example:

import matplotlib as mpl
mpl.rcParams['lines.linewidth'] = 2
mpl.rcParams['lines.color'] = 'r'

Matplotlib also provides a couple of convenience functions for modifying rc settings. The matplotlib.rc() command can be used to modify multiple settings in a single group at once, using keyword arguments:

import matplotlib as mpl
mpl.rc('lines', linewidth=2, color='r')

The matplotlib.rcdefaults() command will restore the standard matplotlib default settings.

There is some degree of validation when setting the values of rcParams, see matplotlib.rcsetup for details.

The matplotlibrc file

matplotlib uses matplotlibrc configuration files to customize all kinds of properties, which we call rc settings or rc parameters. You can control the defaults of almost every property in matplotlib: figure size and dpi, line width, color and style, axes, axis and grid properties, text and font properties and so on. matplotlib looks for matplotlibrc in four locations, in the following order:

1. matplotlibrc in the current working directory, usually used for specific customizations that you do not want to apply elsewhere.

2. $MATPLOTLIBRC/matplotlibrc.

3. It next looks in a user-specific place, depending on your platform:

   • On Linux and FreeBSD, it looks in .config/matplotlib/matplotlibrc (or $XDG_CONFIG_HOME/matplotlib/matplotlibrc) if you’ve customized your environment.
   • On other platforms, it looks in .matplotlib/matplotlibrc.

   See matplotlib configuration and cache directory locations.

4. *INSTALL*/matplotlib/mpl-data/matplotlibrc, where *INSTALL* is something like /usr/lib/python3.5/site-packages on Linux, and maybe C:\Python35\Lib\site-packages on Windows. Every time you install matplotlib, this file will be overwritten, so if you want your customizations to be saved, please move this file to your user-specific matplotlib directory.

To display where the currently active matplotlibrc file was loaded from, one can do the following:

>>> import matplotlib
>>> matplotlib.matplotlib_fname()
'/home/foo/.config/matplotlib/matplotlibrc'

See below for a sample matplotlibrc file.

A sample matplotlibrc file

### MATPLOTLIBRC FORMAT

# This is a sample matplotlib configuration file - you can find a copy
# of it on your system in
# site-packages/matplotlib/mpl-data/matplotlibrc.  If you edit it
# there, please note that it will be overwritten in your next install.
# If you want to keep a permanent local copy that will not be
# overwritten, place it in the following location:
# unix/linux:
#     $HOME/.config/matplotlib/matplotlibrc or
#     $XDG_CONFIG_HOME/matplotlib/matplotlibrc (if $XDG_CONFIG_HOME is set)
# other platforms:
#     $HOME/.matplotlib/matplotlibrc
#
# See http://matplotlib.org/users/customizing.html#the-matplotlibrc-file for
# more details on the paths which are checked for the configuration file.
#
# This file is best viewed in a editor which supports python mode
# syntax highlighting. Blank lines, or lines starting with a comment
# symbol, are ignored, as are trailing comments.  Other lines must
# have the format
#    key : val # optional comment
#
# Colors: for the color values below, you can either use - a
# matplotlib color string, such as r, k, or b - an rgb tuple, such as
# (1.0, 0.5, 0.0) - a hex string, such as ff00ff - a scalar
# grayscale intensity such as 0.75 - a legal html color name, e.g., red,
# blue, darkslategray

### FONT
#
# font properties used by text.Text.  See
# http://matplotlib.org/api/font_manager_api.html for more
# information on font properties.  The 6 font properties used for font
# matching are given below with their default values.
#
# The font.family property has five values: 'serif' (e.g., Times),
# 'sans-serif' (e.g., Helvetica), 'cursive' (e.g., Zapf-Chancery),
# 'fantasy' (e.g., Western), and 'monospace' (e.g., Courier).  Each of
# these font families has a default list of font names in decreasing
# order of priority associated with them.  When text.usetex is False,
# font.family may also be one or more concrete font names.
#
# The font.style property has three values: normal (or roman), italic
# or oblique.  The oblique style will be used for italic, if it is not
# present.
#
# The font.variant property has two values: normal or small-caps.  For
# TrueType fonts, which are scalable fonts, small-caps is equivalent
# to using a font size of 'smaller', or about 83%% of the current font
# size.
#
# The font.weight property has effectively 13 values: normal, bold,
# bolder, lighter, 100, 200, 300, ..., 900.  Normal is the same as
# 400, and bold is 700.  bolder and lighter are relative values with
# respect to the current weight.
#
# The font.stretch property has 11 values: ultra-condensed,
# extra-condensed, condensed, semi-condensed, normal, semi-expanded,
# expanded, extra-expanded, ultra-expanded, wider, and narrower.  This
# property is not currently implemented.
#
# The font.size property is the default font size for text, given in pts.
# 10 pt is the standard value.
#
#font.family         : sans-serif
#font.style          : normal
#font.variant        : normal
#font.weight         : medium
#font.stretch        : normal
# note that font.size controls default text sizes.  To configure
# special text sizes tick labels, axes, labels, title, etc, see the rc
# settings for axes and ticks. Special text sizes can be defined
# relative to font.size, using the following values: xx-small, x-small,
# small, medium, large, x-large, xx-large, larger, or smaller
#font.size           : 10.0
#font.serif          : DejaVu Serif, Bitstream Vera Serif, New Century Schoolbook, Century Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus Roman No9 L, Times New Roman, Times, Palatino, Charter, serif
#font.sans-serif     : DejaVu Sans, Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
#font.cursive        : Apple Chancery, Textile, Zapf Chancery, Sand, Script MT, Felipa, cursive
#font.fantasy        : Comic Sans MS, Chicago, Charcoal, Impact, Western, Humor Sans, xkcd, fantasy

### DATES
# These control the default format strings used in AutoDateFormatter.

# `datetime` for details).  For example using '%%x' will use the locale date representation
# '%%X' will use the locale time representation and '%%c' will use the full locale datetime
# representation.
# These values map to the scales:
#    {'year': 365, 'month': 30, 'day': 1, 'hour': 1/24, 'minute': 1 / (24 * 60)}

# date.autoformatter.year     : %Y

# problems to the mailing-list, please set verbose to "helpful" or "debug"
# and paste the output into your report.

# The "fileo" gives the destination for any calls to verbose.report.
# These objects can a filename, or a filehandle like sys.stdout.
#
# You can override the rc default verbosity from the command line by
