"""
Provides a MATLAB-like plotting framework.

:mod:`~matplotlib.pylab` combines pyplot with numpy into a single namespace.
This is convenient for interactive work, but for programming it
is recommended that the namespaces be kept separate, e.g.::

    import numpy as np
    import matplotlib.pyplot as plt

    x = np.arange(0, 5, 0.1);
    y = np.sin(x)
    plt.plot(x, y)

    ----------

    num : integer or string, optional, default: none
        If not provided, a new figure will be created, and the figure number

        If num is provided, and a figure with this id already exists, make
        it active, and returns a reference to it. If this figure does not

        If num is a string, the window title will be set to this figure's

    figsize : tuple of integers, optional, default: None
        width, height in inches. If not provided, defaults to rc
        figure.figsize.

    dpi : integer, optional, default: None
        resolution of the figure. If not provided, defaults to rc figure.dpi.

    facecolor :

    produces a subaxes in a figure which represents the top plot (i.e. the

    but conceptually this is how the returned subplot has been positioned).

    .. note::

       Creating a new subplot with a position which is entirely inside a

          # first, the plot (and its axes) previously created, will be removed
          plt.subplot(211)
          plt.plot(range(12))
          plt.subplot(212, facecolor='y') # creates 2nd subplot with yellow background

       If you do not want this behavior, use the
       :meth:`~matplotlib.figure.Figure.add_subplot` method or the
       :func:`~matplotlib.pyplot.axes` function instead.

    Keyword arguments:

      *facecolor*:
        The background color of the subplot, which can be any valid
        color specifier.  See :mod:`matplotlib.colors` for more
        information.

      *polar*:
        A boolean flag indicating whether the subplot plot should be
        a polar projection.  Defaults to *False*.

      *projection*:
        A string giving the name of a custom projection to be used

    Create a figure and a set of subplots

    Parameters
    ----------
    nrows, ncols : int, optional, default: 1
        Number of rows/columns of the subplot grid.

    sharex, sharey : bool or {'none', 'all', 'row', 'col'}, default: False
        Controls sharing of properties among x (`sharex`) or y (`sharey`)
        axes:

            - True or 'all': x- or y-axis will be shared among all
              subplots.
            - False or 'none': each subplot x- or y-axis will be
              independent.
            - 'row': each subplot row will share an x- or y-axis.
            - 'col': each subplot column will share an x- or y-axis.

        When subplots have a shared x-axis along a column, only the x tick
        labels of the bottom subplot are visible.  Similarly, when subplots
        have a shared y-axis along a row, only the y tick labels of the first
        column subplot are visible.

    squeeze : bool, optional, default: True
        - If True, extra dimensions are squeezed out from the returned Axes
          object:

            - if only one subplot is constructed (nrows=ncols=1), the
              resulting single Axes object is returned as a scalar.
            - for Nx1 or 1xN subplots, the returned object is a 1D numpy
              object array of Axes objects are returned as numpy 1D arrays.
            - for NxM, subplots with N>1 and M>1 are returned as a 2D arrays.

        - If False, no squeezing at all is done: the returned Axes object is
          always a 2D array containing Axes instances, even if it ends up
          being 1x1.

    subplot_kw : dict, optional
        Dict with keywords passed to the
        :meth:`~matplotlib.figure.Figure.add_subplot` call used to create each
        subplot.

    gridspec_kw : dict, optional
        Dict with keywords passed to the
        :class:`~matplotlib.gridspec.GridSpec` constructor used to create the
        grid the subplots are placed on.

    fig_kw : dict, optional
        Dict with keywords passed to the :func:`figure` call.  Note that all
        keywords not recognized above will be automatically included here.

    Returns
    -------
    fig : :class:`matplotlib.figure.Figure` object

    ax : Axes object or array of Axes objects.

        ax can be either a single :class:`matplotlib.axes.Axes` object or an
        array of Axes objects if more than one subplot was created.  The
        dimensions of the resulting array can be controlled with the squeeze
        keyword, see above.

    Examples
    --------
    First create some toy data:

    >>> x = np.linspace(0, 2*np.pi, 400)
    >>> y = np.sin(x**2)

    Creates just a figure and only one subplot

    >>> fig, ax = plt.subplots()
    >>> ax.plot(x, y)
    >>> ax.set_title('Simple plot')

    Creates two subplots and unpacks the output array immediately

    >>> f, (ax1, ax2) = plt.subplots(1, 2, sharey=True)
    >>> ax1.plot(x, y)
    >>> ax1.set_title('Sharing Y axis')
    >>> ax2.scatter(x, y)

    Creates four polar axes, and accesses them through the returned array

    >>> fig, axes = plt.subplots(2, 2, subplot_kw=dict(polar=True))
    >>> axes[0, 0].plot(x, y)
    >>> axes[1, 1].scatter(x, y)

    Share a X axis with each column of subplots

    >>> plt.subplots(2, 2, sharex='col')

    Share a Y axis with each row of subplots

    >>> plt.subplots(2, 2, sharey='row')

    Share both X and Y axes with all subplots

    >>> plt.subplots(2, 2, sharex='all', sharey='all')

    single letter

      =====   =======
      Alias   Color
      =====   =======
      'b'     blue
      'g'     green

      'k'     black
      'w'     white
      =====   =======

    For a greater range of colors, you have two options.  You can
    specify the color using an html hex string, as in::

      color = '#eeefff'

    or you can pass an R,G,B tuple, where each of R,G,B are in the
    range [0,1].

    You can also use any legal html name for a color, for example::

      color = 'red'
      color = 'burlywood'
      color = 'chartreuse'

    The example below creates a subplot with a dark
    slate gray background::

    All built-in colormaps can be reversed by appending ``_r``: For instance,
    ``gray_r`` is the reverse of ``gray``.

    There are several common color schemes used in visualization:

    Sequential schemes
      for unipolar data that progresses from low to high
    Diverging schemes
      for bipolar data that emphasizes positive or negative deviations from a
      central value
    Cyclic schemes
      meant for plotting values that wrap around at the
      endpoints, such as phase angle, wind direction, or time of day
    Qualitative schemes
      for nominal data that has no inherent ordering, where color is used
      only to distinguish categories

    The base colormaps are derived from those of the same name provided
    with Matlab:

    For the above list only, you can also set the colormap using the
    corresponding pylab shortcut interface function, similar to Matlab::

      imshow(X)
      hot()
      jet()

    The next set of palettes are from the `Yorick scientific visualisation
    package <http://dhmunro.github.io/yorick-doc/>`_, an evolution of
    the GIST package, both by David H. Munro:

      cubehelix     Unlike most other color schemes cubehelix was designed
                    by D.A. Green to be monotonically increasing in terms
                    of perceived brightness. Also, when printed on a black
                    and white postscript printer, the scheme results in a
                    greyscale with monotonically increasing brightness.
                    This color scheme is named cubehelix because the r,g,b
                    values produced can be visualised as a squashed helix

    *cols* is a sequence of column identifiers to plot.  An identifier
    is either an int or a string.  If it is an int, it indicates the

    matplotlib will make column headers lower case, replace spaces with
    underscores, and remove all illegal characters; so ``'Adj Close*'``
    will have name ``'adj_close'``.

    - If len(*cols*) == 1, only that column will be plotted on the *y* axis.

    - If len(*cols*) > 1, the first element will be an identifier for

      column indexes for multiple subplots if *subplots* is *True*
      (the default), or for lines in a single subplot if *subplots*
      is *False*.

    *plotfuncs*, if not *None*, is a dictionary mapping identifier to
    an :class:`~matplotlib.axes.Axes` plotting function as a string.
    Default is 'plot', other choices are 'semilogy', 'fill', 'bar',
    etc.  You must use the same type of identifier in the *cols*
    vector as you use in the *plotfuncs* dictionary, e.g., integer
    column numbers in both or column names in both. If *subplots*
    is *False*, then including any function such as 'semilogy'
