"""

`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)

plt.show()

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 </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)

plt.show()

See :ref:`api_interfaces` for an explanation of the tradeoffs between the

implicit and explicit interfaces.

----------

block : bool, optional

Whether to wait for all figures to be closed before returning.

If `True` block and run the GUI main loop until all figure windows

are closed.

If `False` ensure that all figure windows are displayed and return

immediately. In this case, you are responsible for ensuring

that the event loop is running to have responsive figures.

Defaults to True in non-interactive mode and to False in interactive

mode (see `.pyplot.isinteractive`).

See Also

--------

ion : Enable interactive mode, which shows / updates the figure after

every plotting command, so that calling ``show()`` is not necessary.

ioff : Disable interactive mode.

savefig : Save the figure to an image file instead of showing it on screen.

Notes

-----

**Saving figures to file and showing a window at the same time**

If you want an image file as well as a user interface window, use

`.pyplot.savefig` before `.pyplot.show`. At the end of (a blocking)

``show()`` the figure is closed and thus unregistered from pyplot. Calling

`.pyplot.savefig` afterwards would save a new and thus empty figure. This

limitation of command order does not apply if the show is non-blocking or

if you keep a reference to the figure and use `.Figure.savefig`.

**Auto-show in jupyter notebooks**

The jupyter backends (activated via ``%matplotlib inline``,

``%matplotlib notebook``, or ``%matplotlib widget``), call ``show()`` at

the end of every cell by default. Thus, you usually don't have to call it

explicitly there.

"""

Create a new figure, or activate an existing figure.

Parameters

----------

num : int or str or `.Figure` or `.SubFigure`, optional

A unique identifier for the figure.

If a figure with that identifier already exists, this figure is made

active and returned. An integer refers to the ``Figure.number``

attribute, a string refers to the figure label.

If there is no figure with the identifier or *num* is not given, a new

figure is created, made active and returned. If *num* is an int, it

will be used for the ``Figure.number`` attribute, otherwise, an

auto-generated integer value is used (starting at 1 and incremented

for each new figure). If *num* is a string, the figure label and the

window title is set to this value. If num is a ``SubFigure``, its

parent ``Figure`` is activated.

If *num* is a Figure instance that is already tracked in pyplot, it is

activated. If *num* is a Figure instance that is not tracked in pyplot,

it is added to the tracked figures and activated.

figsize : (float, float) or (float, float, str), default: :rc:`figure.figsize`

The figure dimensions. This can be

- a tuple ``(width, height, unit)``, where *unit* is one of "inch", "cm",

"px".

- a tuple ``(x, y)``, which is interpreted as ``(x, y, "inch")``.

One of *width* or *height* may be ``None``; the respective value is taken

from :rc:`figure.figsize`.

dpi : float, default: :rc:`figure.dpi`

The resolution of the figure in dots-per-inch.

facecolor : :mpltype:`color`, default: :rc:`figure.facecolor`

The background color.

edgecolor : :mpltype:`color`, default: :rc:`figure.edgecolor`

The border color.

frameon : bool, default: True

If False, suppress drawing the figure frame.

FigureClass : subclass of `~matplotlib.figure.Figure`

If set, an instance of this subclass will be created, rather than a

plain `.Figure`.

clear : bool, default: False

If True and the figure already exists, then it is cleared.

layout : {'constrained', 'compressed', 'tight', 'none', `.LayoutEngine`, None}, \

default: None

The layout mechanism for positioning of plot elements to avoid

overlapping Axes decorations (labels, ticks, etc). Note that layout

managers can measurably slow down figure display.

- 'constrained': The constrained layout solver adjusts Axes sizes

to avoid overlapping Axes decorations. Can handle complex plot

layouts and colorbars, and is thus recommended.

See :ref:`constrainedlayout_guide`

for examples.

- 'compressed': uses the same algorithm as 'constrained', but

removes extra space between fixed-aspect-ratio Axes. Best for

simple grids of Axes.

- 'tight': Use the tight layout mechanism. This is a relatively

simple algorithm that adjusts the subplot parameters so that

decorations do not overlap. See `.Figure.set_tight_layout` for

further details.

- 'none': Do not use a layout engine.

- A `.LayoutEngine` instance. Builtin layout classes are

`.ConstrainedLayoutEngine` and `.TightLayoutEngine`, more easily

accessible by 'constrained' and 'tight'. Passing an instance

allows third parties to provide their own layout engine.
