# 1 matplotlib的两个常用配置 #

## 1.1 解决图片无法生成汉语文字的问题 ##

使用这个命令，可以使得图片中的汉语得到显示，默认是无法显示汉语的。

from pylab import mpl
    mpl.rcParams['font.sans-serif'] = ['FangSong']  # 设置matplotlib可以显示汉语
    mpl.rcParams['axes.unicode_minus'] = False

## 1.2 配置图片中所有的文字字体大小 ##

使用这个命令，可以将图片中所有的字体大小进行调整，解决原始图像中文字过小的问题。

from pylab import mpl
    mpl.rcParams['font.size'] = 13

# 2 matplotlib的rcParams #

很多图形的参数都是可以通过rcParams参数进行配置的，在matplotlib中有很多全局的参数都可以使用该方法进行配置，如上述两个常见的配置一样，其他配置也是使用这种键-值的方式进行修改。  
在C:\\Python37\\Lib\\site-packages\\matplotlib\\mpl-data路径下，matplotlibrc文件即是所有的可配置内容，其文件内部内容如下所示：

## The default backend. If you omit this parameter, the first
    ## working backend from the following list is used:
    ## MacOSX Qt5Agg Qt4Agg Gtk3Agg GTK3Cairo TkAgg WxAgg Agg Cairo
    ##
    ## Other choices include: WX PS PDF SVG Template.
    ##
    ## You can also deploy your own backend outside of matplotlib by
    ## referring to the module name (which must be in the PYTHONPATH) as
    ## 'module://my_backend'.
    backend: TkAgg
    ## Note that this can be overridden by the environment variable
    ## QT_API used by Enthought Tool Suite (ETS); valid values are
    ## "pyqt" and "pyside". The "pyqt" setting has the side effect of
    ## forcing the use of Version 2 API for QString and QVariant.
    
    ## The port to use for the web server in the WebAgg backend.
    #webagg.port : 8988
    
    ## The address on which the WebAgg web server should be reachable
    #webagg.address : 127.0.0.1
    
    ## If webagg.port is unavailable, a number of other random ports will
    ## be tried until one that is available is found.
    #webagg.port_retries : 50
    
    ## When True, open the webbrowser to the plot that is shown
    #webagg.open_in_browser : True
    
    ## if you are running pyplot inside a GUI and your backend choice
    ## conflicts, we will automatically try to find a compatible one for
    ## you if backend_fallback is True
    #backend_fallback: True
    
    #interactive : False
    #toolbar : toolbar2 ## None | toolbar2 ("classic" is deprecated)
    #timezone : UTC ## a pytz timezone string, e.g., US/Central or Europe/Paris
    
    ## Where your matplotlib data lives if you installed to a non-default
    ## location. This is where the matplotlib fonts, bitmaps, etc reside

    #### 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 : normal
    #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, Computer Modern Roman, 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, Computer Modern Sans Serif, 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, ImpactWestern, Humor Sans, xkcd, fantasy
    #font.monospace : DejaVu Sans Mono, Bitstream Vera Sans Mono, Computer Modern Typewriter, Andale Mono, Nimbus Mono L, Courier New, Courier, Fixed, Terminal, monospace
    
    #### TEXT
    ## text properties used by text.Text. See
    ## http://matplotlib.org/api/artist_api.html#module-matplotlib.text for more
    ## information on text properties
    #text.color : black
    
    #### LaTeX customizations. See http://wiki.scipy.org/Cookbook/Matplotlib/UsingTex
    #text.usetex : False ## use latex for all text handling. The following fonts
                                  ## are supported through the usual rc parameter settings:
                                  ## new century schoolbook, bookman, times, palatino,
                                  ## zapf chancery, charter, serif, sans-serif, helvetica,
                                  ## avant garde, courier, monospace, computer modern roman,
                                  ## computer modern sans serif, computer modern typewriter
                                  ## If another font is desired which can loaded using the
                                  ## LaTeX \usepackage command, please inquire at the
                                  ## matplotlib mailing list
    #text.latex.preamble : ## IMPROPER USE OF THIS FEATURE WILL LEAD TO LATEX FAILURES

                                ## type1cm, textcomp. Adobe Postscript (PSSNFS) font packages
                                ## may also be loaded, depending on your font settings
    #text.latex.preview : False
    
    #text.hinting : auto ## May be one of the following:
                           ## none: Perform no hinting
                           ## auto: Use FreeType's autohinter
                           ## native: Use the hinting information in the
                           # font file, if available, and if your
                           # FreeType library supports it
                           ## either: Use the native hinting information,
                           # or the autohinter if none is available.
                           ## For backward compatibility, this value may also be
                           ## True === 'auto' or False === 'none'.
    #text.hinting_factor : 8 ## Specifies the amount of softness for hinting in the
                             ## horizontal direction. A value of 1 will hint to full
                             ## pixels. A value of 2 will hint to half pixels etc.
    #text.antialiased : True ## If True (default), the text will be antialiased.
                             ## This only affects the Agg backend.
    
    ## The following settings allow you to select the fonts in math mode.

    #### DATES
    ## These control the default format strings used in AutoDateFormatter.
    ## Any valid format datetime format string can be used (see the python
    ## `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
