# Note: The first part of this file can be modified in place, but the latter # part is autogenerated by the boilerplate.py script. """ `matplotlib.pyplot` is a state-based interface to matplotlib. It provides an implicit, MATLAB-like, way of plotting. It also opens figures on your screen, and acts as the figure GUI manager. pyplot is mainly intended for interactive plots and simple cases of programmatic plot generation:: import numpy as np import matplotlib.pyplot as plt x = np.arange(0, 5, 0.1) y = np.sin(x) plt.plot(x, y) The explicit (object-oriented) API is recommended for complex plots, though pyplot is still usually used to create the figure and often the axes in the figure. See `.pyplot.figure`, `.pyplot.subplots`, and `.pyplot.subplot_mosaic` to create figures, and :doc:`Axes API <../axes_api>` for the plotting methods on an axes:: import numpy as np import matplotlib.pyplot as plt x = np.arange(0, 5, 0.1) y = np.sin(x) fig, ax = plt.subplots() ax.plot(x, y) """ import functools import importlib import inspect import logging from numbers import Number import re import sys import time try: import threading except ImportError: import dummy_threading as threading from cycler import cycler import matplotlib import matplotlib.colorbar import matplotlib.image from matplotlib import _api from matplotlib import rcsetup, style from matplotlib import _pylab_helpers, interactive from matplotlib import cbook from matplotlib import docstring from matplotlib.backend_bases import FigureCanvasBase, MouseButton from matplotlib.figure import Figure, figaspect from matplotlib.gridspec import GridSpec, SubplotSpec from matplotlib import rcParams, rcParamsDefault, get_backend, rcParamsOrig from matplotlib.rcsetup import interactive_bk as _interactive_bk from matplotlib.artist import Artist from matplotlib.axes import Axes, Subplot from matplotlib.projections import PolarAxes from matplotlib import mlab # for detrend_none, window_hanning from matplotlib.scale import get_scale_names from matplotlib import cm from matplotlib.cm import _colormaps as colormaps, get_cmap, register_cmap import numpy as np # We may not need the following imports here: from matplotlib.colors import Normalize from matplotlib.lines import Line2D from matplotlib.text import Text, Annotation from matplotlib.patches import Polygon, Rectangle, Circle, Arrow from matplotlib.widgets import Button, Slider, Widget from .ticker import ( TickHelper, Formatter, FixedFormatter, NullFormatter, FuncFormatter, FormatStrFormatter, ScalarFormatter, LogFormatter, LogFormatterExponent, LogFormatterMathtext, Locator, IndexLocator, FixedLocator, NullLocator, LinearLocator, LogLocator, AutoLocator, MultipleLocator, MaxNLocator) _log = logging.getLogger(__name__) def _copy_docstring_and_deprecators(method, func=None): if func is None: return functools.partial(_copy_docstring_and_deprecators, method) decorators = [docstring.copy(method)] # Check whether the definition of *method* includes @_api.rename_parameter # or @_api.make_keyword_only decorators; if so, propagate them to the # pyplot wrapper as well. while getattr(method, "__wrapped__", None) is not None: decorator = _api.deprecation.DECORATORS.get(method) if decorator: decorators.append(decorator) method = method.__wrapped__ for decorator in decorators[::-1]: func = decorator(func) return func ## Global ## _IP_REGISTERED = None _INSTALL_FIG_OBSERVER = False def install_repl_displayhook(): """ Install a repl display hook so that any stale figure are automatically redrawn when control is returned to the repl.

Call signatures:: subplot(nrows, ncols, index, **kwargs) subplot(pos, **kwargs) subplot(**kwargs) subplot(ax) Parameters ---------- *args : int, (int, int, *index*), or `.SubplotSpec`, default: (1, 1, 1) The position of the subplot described by one of - Three integers (*nrows*, *ncols*, *index*). The subplot will take the *index* position on a grid with *nrows* rows and *ncols* columns. *index* starts at 1 in the upper left corner and increases to the right. *index* can also be a two-tuple specifying the (*first*, *last*) indices (1-based, and including *last*) of the subplot, e.g., ``fig.add_subplot(3, 1, (1, 2))`` makes a subplot that spans the upper 2/3 of the figure. - A 3-digit integer. The digits are interpreted as if given separately as three single-digit integers, i.e. ``fig.add_subplot(235)`` is the same as ``fig.add_subplot(2, 3, 5)``. Note that this can only be used if there are no more than 9 subplots. - A `.SubplotSpec`. projection : {None, 'aitoff', 'hammer', 'lambert', 'mollweide', \ 'polar', 'rectilinear', str}, optional The projection type of the subplot (`~.axes.Axes`). *str* is the name of a custom projection, see `~matplotlib.projections`. The default None results in a 'rectilinear' projection. polar : bool, default: False If True, equivalent to projection='polar'. sharex, sharey : `~.axes.Axes`, optional Share the x or y `~matplotlib.axis` with sharex and/or sharey. The axis will have the same limits, ticks, and scale as the axis of the shared axes. label : str A label for the returned axes. Returns ------- `.axes.SubplotBase`, or another subclass of `~.axes.Axes` The axes of the subplot. The returned axes base class depends on the projection used. It is `~.axes.Axes` if rectilinear projection is used and `.projections.polar.PolarAxes` if polar projection is used. The returned axes is then a subplot subclass of the base class. Other Parameters ---------------- **kwargs This method also takes the keyword arguments for the returned axes base class; except for the *figure* argument. The keyword arguments for the rectilinear base class `~.axes.Axes` can be found in the following table but there might also be other keyword arguments if another projection is used. %(Axes:kwdoc)s Notes ----- Creating a new Axes will delete any pre-existing Axes that overlaps with it beyond sharing a boundary:: import matplotlib.pyplot as plt # plot a line, implicitly creating a subplot(111) plt.plot([1, 2, 3]) # now create a subplot which represents the top plot of a grid # with 2 rows and 1 column. Since this subplot will overlap the # first, the plot (and its axes) previously created, will be removed plt.subplot(211) If you do not want this behavior, use the `.Figure.add_subplot` method or the `.pyplot.axes` function instead. If no *kwargs* are passed and there exists an Axes in the location specified by *args* then that Axes will be returned rather than a new Axes being created. If *kwargs* are passed and there exists an Axes in the location specified by *args*, the projection type is the same, and the *kwargs* match with the existing Axes, then the existing Axes is returned. Otherwise a new Axes is created with the specified parameters. We save a reference to the *kwargs* which we use for this comparison. If any of the values in *kwargs* are mutable we will not detect the case where they are mutated. In these cases we suggest using `.Figure.add_subplot` and the explicit Axes API rather than the implicit pyplot API.
