"""\nAdjust subplot layouts so that there are no overlapping Axes or Axes\ndecorations. All Axes decorations are dealt with (labels, ticks, titles,\nticklabels) and some dependent artists are also dealt with (colorbar,\nsuptitle).\n\nLayout is done via `~matplotlib.gridspec`, with one constraint per gridspec,\nso it is possible to have overlapping Axes if the gridspecs overlap (i.e.\nusing `~matplotlib.gridspec.GridSpecFromSubplotSpec`). Axes placed using\n``figure.subplots()`` or ``figure.add_subplots()`` will participate in the\nlayout. Axes manually placed via ``figure.add_axes()`` will not.\n\nSee Tutorial: :ref:`constrainedlayout_guide`\n\nGeneral idea:\n-------------\n\nFirst, a figure has a gridspec that divides the figure into nrows and ncols,\nwith heights and widths set by ``height_ratios`` and ``width_ratios``,\noften just set to 1 for an equal grid.\n\nSubplotspecs that are derived from this gridspec can contain either a\n``SubPanel``, a ``GridSpecFromSubplotSpec``, or an ``Axes``. The ``SubPanel``\nand ``GridSpecFromSubplotSpec`` are dealt with recursively and each contain an\nanalogous layout.\n\nEach ``GridSpec`` has a ``_layoutgrid`` attached to it. The ``_layoutgrid``\nhas the same logical layout as the ``GridSpec``. Each row of the grid spec\nhas a top and bottom "margin" and each column has a left and right "margin".\nThe "inner" height of each row is constrained to be the same (or as modified\nby ``height_ratio``), and the "inner" width of each column is\nconstrained to be the same (as modified by ``width_ratio``), where "inner"\nis the width or height of each column/row minus the size of the margins.\n\nThen the size of the margins for each row and column are determined as the\nmax width of the decorators on each Axes that has decorators in that margin.\nFor instance, a normal Axes would have a left margin that includes the\nleft ticklabels, and the ylabel if it exists. The right margin may include a\ncolorbar, the bottom margin the xaxis decorations, and the top margin the\ntitle.\n\nWith these constraints, the solver then finds appropriate bounds for the\ncolumns and rows. It's possible that the margins take up the whole figure,\nin which case the algorithm is not applied and a warning is raised.\n\nSee the tutorial :ref:`constrainedlayout_guide`\nfor more discussion of the algorithm with examples.\n"""\n\nimport logging\n\nimport numpy as np\n\nfrom matplotlib import _api, artist as martist\nimport matplotlib.transforms as mtransforms\nimport matplotlib._layoutgrid as mlayoutgrid\n\n\n_log = logging.getLogger(__name__)\n\n\n######################################################\ndef do_constrained_layout(fig, h_pad, w_pad,\n hspace=None, wspace=None, rect=(0, 0, 1, 1),\n compress=False):\n """\n Do the constrained_layout.

"""\nAn object-oriented plotting library.\n\nA procedural interface is provided by the companion pyplot module,\nwhich may be imported directly, e.g.::\n\n import matplotlib.pyplot as plt\n\nor using ipython::\n\n ipython\n\nat your terminal, followed by::\n\n In [1]: %matplotlib\n In [2]: import matplotlib.pyplot as plt\n\nat the ipython shell prompt.\n\nFor the most part, direct use of the explicit object-oriented library is\nencouraged when programming; the implicit pyplot interface is primarily for\nworking interactively. The exceptions to this suggestion are the pyplot\nfunctions `.pyplot.figure`, `.pyplot.subplot`, `.pyplot.subplots`, and\n`.pyplot.savefig`, which can greatly simplify scripting. See\n:ref:`api_interfaces` for an explanation of the tradeoffs between the implicit\nand explicit interfaces.\n\nModules include:\n\n:mod:`matplotlib.axes`\n The `~.axes.Axes` class. Most pyplot functions are wrappers for\n `~.axes.Axes` methods. The axes module is the highest level of OO\n access to the library.\n\n:mod:`matplotlib.figure`\n The `.Figure` class.\n\n:mod:`matplotlib.artist`\n The `.Artist` base class for all classes that draw things.\n\n:mod:`matplotlib.lines`\n The `.Line2D` class for drawing lines and markers.\n\n:mod:`matplotlib.patches`\n Classes for drawing polygons.\n\n:mod:`matplotlib.text`\n The `.Text` and `.Annotation` classes.\n\n:mod:`matplotlib.image`\n The `.AxesImage` and `.FigureImage` classes.\n\n:mod:`matplotlib.collections`\n Classes for efficient drawing of groups of lines or polygons.\n\n:mod:`matplotlib.colors`\n Color specifications and making colormaps.\n\n:mod:`matplotlib.cm`\n Colormaps, and the `.ScalarMappable` mixin class for providing color\n mapping functionality to other classes.\n\n:mod:`matplotlib.ticker`\n Calculation of tick mark locations and formatting of tick labels.\n\n:mod:`matplotlib.backends`\n A subpackage with modules for various GUI libraries and output formats.\n\nThe base matplotlib namespace includes:\n\n`~matplotlib.rcParams`\n Default configuration settings; their defaults may be overridden using\n a :file:`matplotlibrc` file.\n\n`~matplotlib.use`\n Setting the Matplotlib backend. This should be called before any\n figure is created, because it is not possible to switch between\n different GUI backends after that.\n\nThe following environment variables can be used to customize the behavior:\n\n:envvar:`MPLBACKEND`\n This optional variable can be set to choose the Matplotlib backend. See\n :ref:`what-is-a-backend`.\n\n:envvar:`MPLCONFIGDIR`\n This is the directory used to store user customizations to\n Matplotlib, as well as some caches to improve performance. If\n :envvar:`MPLCONFIGDIR` is not defined, :file:`{HOME}/.config/matplotlib`\n and :file:`{HOME}/.cache/matplotlib` are used on Linux, and\n :file:`{HOME}/.matplotlib` on other platforms, if they are\n writable. Otherwise, the Python standard library's `tempfile.gettempdir`\n is used to find a base directory in which the :file:`matplotlib`\n subdirectory is created.\n\nMatplotlib was initially written by John D. Hunter (1968-2012) and is now\ndeveloped and maintained by a host of others.\n\nOccasionally the internal documentation (python docstrings) will refer\nto MATLAB®, a registered trademark of The MathWorks, Inc.\n\n"""\n\n__all__ = [\n "__bibtex__",\n "__version__",\n "__version_info__",\n "set_loglevel",\n "ExecutableNotFoundError",\n "get_configdir",\n "get_cachedir",\n "get_data_path",\n "matplotlib_fname",\n "MatplotlibDeprecationWarning",\n "RcParams",\n "rc_params",\n "rc_params_from_file",\n "rcParamsDefault",\n "rcParams",\n "rcParamsOrig",\n "defaultParams",\n "rc",\n "rcdefaults",\n "rc_file_defaults",\n "rc_file",\n "rc_context",\n "use",\n "get_backend",\n "interactive",\n "is_interactive",\n "colormaps",\n "multivar_colormaps",\n "bivar_colormaps",\n "color_sequences",\n]\n\n\nimport atexit\nfrom collections import namedtuple\nfrom collections.abc import MutableMapping\nimport contextlib\nimport functools\nimport importlib\nimport inspect\nfrom inspect import Parameter\nimport locale\nimport logging\nimport os\nfrom pathlib import Path\nimport pprint\nimport re\nimport shutil\nimport subprocess\nimport sys\nimport tempfile\n\nfrom packaging.version import parse as parse_version\n\n# cbook must import matplotlib only within function\n# definitions, so it is safe to import from it here.\nfrom . import _api, _version, cbook, _docstring, rcsetup\nfrom matplotlib._api import MatplotlibDeprecationWarning\nfrom matplotlib.rcsetup import cycler # noqa: F401\n\n\n_log = logging.getLogger(__name__)\n\n__bibtex__ = r"""@Article{Hunter:2007,\n Author = {Hunter, J.
