-### MATPLOTLIBRC FORMAT
-
-# This is a sample matplotlib configuration file. It should be placed
-# in HOME/.matplotlib/matplotlibrc (unix/linux like systems) and
-# C:\Documents and Settings\yourname\.matplotlib (win32 systems)
-#
-# By default, the installer will overwrite the existing file in the
-# install path, so if you want to preserve your's, please move it to
-# your HOME dir and set the environment variable if necessary.
-#
-# 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 (no '#' symbol)
-# - a scalar grayscale intensity such as 0.75
-# - a legal html color name, eg red, blue, darkslategray
-
-#### CONFIGURATION BEGINS HERE
-# the default backend; one of GTK GTKAgg GTKCairo FltkAgg QtAgg TkAgg
-# Agg Cairo GD GDK Paint PS PDF SVG Template
-backend : TkAgg
-numerix : numpy # numpy, Numeric or numarray
-#maskedarray : False # True to use external maskedarray module
- # instead of numpy.ma; this is a temporary
- # setting for testing maskedarray.
-#interactive : False # see http://matplotlib.sourceforge.net/interactive.html
-#toolbar : toolbar2 # None | classic | toolbar2
-#timezone : UTC # a pytz timezone string, eg 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
-#datapath : /home/jdhunter/mpldata
-
-
-### LINES
-# See http://matplotlib.sourceforge.net/matplotlib.lines.html for more
-# information on line properties.
-#lines.linewidth : 1.0 # line width in points
-#lines.linestyle : - # solid line
-#lines.color : blue
-#lines.marker : None # the default marker
-#lines.markeredgewidth : 0.5 # the line width around the marker symbol
-#lines.markersize : 6 # markersize, in points
-#lines.dash_joinstyle : miter # miter|round|bevel
-#lines.dash_capstyle : butt # butt|round|projecting
-#lines.solid_joinstyle : miter # miter|round|bevel

-### PATCHES
-# Patches are graphical objects that fill 2D space, like polygons or
-# circles. See
-# http://matplotlib.sourceforge.net/matplotlib.patches.html for more
-# information on patch properties
-#patch.linewidth : 1.0 # edge width in points
-#patch.facecolor : blue
-#patch.edgecolor : black
-#patch.antialiased : True # render patches in antialised (no jaggies)
-
-### FONT
-#
-# font properties used by text.Text. See
-# http://matplotlib.sourceforge.net/matplotlib.font_manager.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.
-#
-# 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.
-# 12pt 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 : 12.0
-#font.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 : Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
-#font.cursive : Apple Chancery, Textile, Zapf Chancery, Sand, cursive
-#font.fantasy : Comic Sans MS, Chicago, Charcoal, Impact, Western, fantasy
-#font.monospace : Bitstream Vera Sans Mono, Andale Mono, Nimbus Mono L, Courier New, Courier, Fixed, Terminal, monospace
-
-### TEXT
-# text properties used by text.Text. See
-# http://matplotlib.sourceforge.net/matplotlib.text.html for more
-# information on text properties
-
-#text.color : black
-
-### LaTeX customizations. See http://www.scipy.org/Wiki/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.unicode : False # use "ucs" and "inputenc" LaTeX packages for handling

- # that are included in the LaTeX document preamble.
- # An example:
- # text.latex.preamble : \usepackage{bm},\usepackage{euler}
- # The following packages are always loaded with usetex, so
- # beware of package collisions: color, geometry, graphicx,
- # type1cm, textcomp. Adobe Postscript (PSSNFS) font packages
- # may also be loaded, depending on your font settings
-#text.dvipnghack : False # some versions of dvipng don't handle
- # alpha channel properly. Use True to correct and flush
- # ~/.matplotlib/tex.cache before testing
-#text.markup : 'plain' # Affects how text, such as titles and labels, are
- # interpreted by default.
- # 'plain': As plain, unformatted text
- # 'tex': As TeX-like text. Text between $'s will be
- # formatted as a TeX math expression.
- # This setting has no effect when text.usetex is True.
- # In that case, all text will be sent to TeX for
- # processing.
-
-# The following settings allow you to select the fonts in math mode.
-# They map from a TeX font name to a set of arguments for the FontProperties constructor.
-# (See FontProperties for more details).
-# These settings are only used if mathtext.use_cm is False, otherwise, the
-# Bakoma TeX Computer Modern fonts are used.
