matplotlib.figure.Figure

class matplotlib.figure.Figure(figsize=None, dpi=None, facecolor=None, edgecolor=None, linewidth=0.0, frameon=None, subplotpars=None, tight_layout=None, constrained_layout=None)[source]

Bases: matplotlib.artist.Artist

The top level container for all the plot elements.

The Figure instance supports callbacks through a callbacks attribute which is a CallbackRegistry instance. The events you can connect to are 'dpi_changed', and the callback will be called with func(fig) where fig is the Figure instance.

Attributes:
patch

The Rectangle instance representing the figure background patch.

suppressComposite

For multiple figure images, the figure will make composite images depending on the renderer option_image_nocomposite function. If suppressComposite is a boolean, this will override the renderer.
Parameters:
figsize2-tuple of floats, default: rcParams["figure.figsize"] (default: [6.4, 4.8])

Figure dimension (width, height) in inches.

dpifloat, default: rcParams["figure.dpi"] (default: 100.0)

Dots per inch.

facecolordefault: rcParams["figure.facecolor"] (default: 'white')

The figure patch facecolor.

edgecolordefault: rcParams["figure.edgecolor"] (default: 'white')

The figure patch edge color.

linewidthfloat

The linewidth of the frame (i.e. the edge linewidth of the figure patch).

frameonbool, default: rcParams["figure.frameon"] (default: True)

If False, suppress drawing the figure background patch.

subplotparsSubplotParams

Subplot parameters. If not given, the default subplot parameters rcParams["figure.subplot.*"] are used.

tight_layoutbool or dict, default: rcParams["figure.autolayout"] (default: False)

If False use subplotpars. If True adjust subplot parameters using tight_layout with default padding. When providing a dict containing the keys pad, w_pad, h_pad, and rect, the default tight_layout paddings will be overridden.

constrained_layoutbool, default: rcParams["figure.constrained_layout.use"] (default: False)

If True use constrained layout to adjust positioning of plot elements. Like tight_layout, but designed to be more flexible. See Constrained Layout Guide for examples. (Note: does not work with add_subplot or subplot2grid.)

Return repr(self).

__setstate__(self, state)[source]
__str__(self)[source]

Return str(self).

add_artist(self, artist, clip=False)[source]

Add an Artist to the figure.

Usually artists are added to axes objects using Axes.add_artist; this method can be used in the rare cases where one needs to add artists directly to the figure instead.

Parameters:
artistArtist

The artist to add to the figure. If the added artist has no transform previously set, its transform will be set to figure.transFigure.

clipbool, default: False

Whether the added artist should be clipped by the figure patch.
Returns:
Artist

The added artist.
add_axes(self, *args, **kwargs)[source]

Add an axes to the figure.

Call signatures:

add_axes(rect, projection=None, polar=False, **kwargs)
add_axes(ax)
Parameters:
rectsequence of float

The dimensions [left, bottom, width, height] of the new axes. All quantities are in fractions of figure width and height.

projection{None, 'aitoff', 'hammer', 'lambert', 'mollweide', 'polar', 'rectilinear', str}, optional

The projection type of the Axes. str is the name of a custom projection, see projections. The default None results in a 'rectilinear' projection.

polarbool, default: False

If True, equivalent to projection='polar'.

sharex, shareyAxes, optional

Share the x or y axis with sharex and/or sharey. The axis will have the same limits, ticks, and scale as the axis of the shared axes.

labelstr

A label for the returned axes.
Returns:
Axes, or a subclass of Axes

The returned axes class depends on the projection used. It is Axes if rectilinear projection is used and projections.polar.PolarAxes if polar projection is used.
Other Parameters:
**kwargs

This method also takes the keyword arguments for the returned axes class. The keyword arguments for the rectilinear axes class Axes can be found in the following table but there might also be other keyword arguments if another projection is used, see the actual axes class.

Notes

If the figure already has an axes with key (args, kwargs) then it will simply make that axes current and return it. This behavior is deprecated. Meanwhile, if you do not want this behavior (i.e., you want to force the creation of a new axes), you must use a unique set of args and kwargs. The axes label attribute has been exposed for this purpose: if you want two axes that are otherwise identical to be added to the figure, make sure you give them unique labels.

In rare circumstances, add_axes may be called with a single argument, a axes instance already created in the present figure but not in the figure's list of axes.

Examples

Some simple examples:

rect = l, b, w, h
fig = plt.figure()
fig.add_axes(rect, label=label1)
fig.add_axes(rect, label=label2)
fig.add_axes(rect, frameon=False, facecolor='g')
fig.add_axes(rect, polar=True)
ax = fig.add_axes(rect, projection='polar')
fig.delaxes(ax)
fig.add_axes(ax)
add_axobserver(self, func)[source]

Whenever the axes state change, func(self) will be called.

add_gridspec(self, nrows=1, ncols=1, **kwargs)[source]

Return a GridSpec that has this figure as a parent. This allows complex layout of axes in the figure.

Parameters:
nrowsint, default: 1

Number of rows in grid.

ncolsint, default: 1

Number or columns in grid.
Returns:
GridSpec
Other Parameters:
**kwargs

Keyword arguments are passed to GridSpec.

See also

matplotlib.pyplot.subplots

Examples

Adding a subplot that spans two rows:

fig = plt.figure()
gs = fig.add_gridspec(2, 2)
ax1 = fig.add_subplot(gs[0, 0])
ax2 = fig.add_subplot(gs[1, 0])
# spans two rows:
ax3 = fig.add_subplot(gs[:, 1])
add_subplot(self, *args, **kwargs)[source]

Add an Axes to the figure as part of a subplot arrangement.

Call signatures:

add_subplot(nrows, ncols, index, **kwargs)
add_subplot(pos, **kwargs)
add_subplot(ax)
add_subplot()
Parameters:
*argsint, (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.

In rare circumstances, add_subplot may be called with a single argument, a subplot axes instance already created in the present figure but not in the figure's list of axes.

projection{None, 'aitoff', 'hammer', 'lambert', 'mollweide', 'polar', 'rectilinear', str}, optional

The projection type of the subplot (Axes). str is the name of a custom projection, see projections. The default None results in a 'rectilinear' projection.

polarbool, default: False

If True, equivalent to projection='polar'.

sharex, shareyAxes, optional

Share the x or y axis with sharex and/or sharey. The axis will have the same limits, ticks, and scale as the axis of the shared axes.

labelstr

A label for the returned axes.
Returns:
axes.SubplotBase, or another subclass of Axes

The axes of the subplot. The returned axes base class depends on the projection used. It is 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 can be found in the following table but there might also be other keyword arguments if another projection is used.

Notes

If the figure already has a subplot with key (args, kwargs) then it will simply make that subplot current and return it. This behavior is deprecated. Meanwhile, if you do not want this behavior (i.e., you want to force the creation of a new subplot), you must use a unique set of args and kwargs. The axes label attribute has been exposed for this purpose: if you want two subplots that are otherwise identical to be added to the figure, make sure you give them unique labels.

Examples

fig = plt.figure()

fig.add_subplot(231)
ax1 = fig.add_subplot(2, 3, 1)  # equivalent but more general

fig.add_subplot(232, frameon=False)  # subplot with no frame
fig.add_subplot(233, projection='polar')  # polar subplot
fig.add_subplot(234, sharex=ax1)  # subplot sharing x-axis with ax1
fig.add_subplot(235, facecolor="red")  # red subplot

ax1.remove()  # delete ax1 from the figure
fig.add_subplot(ax1)  # add ax1 back to the figure
align_labels(self, axs=None)[source]

Align the xlabels and ylabels of subplots with the same subplots row or column (respectively) if label alignment is being done automatically (i.e. the label position is not manually set).

Alignment persists for draw events after this is called.

Parameters:
axslist of Axes

Optional list (or ndarray) of Axes to align the labels. Default is to align all axes on the figure.

See also

matplotlib.figure.Figure.align_xlabels
matplotlib.figure.Figure.align_ylabels
align_xlabels(self, axs=None)[source]

Align the xlabels of subplots in the same subplot column if label alignment is being done automatically (i.e. the label position is not manually set).

Alignment persists for draw events after this is called.

If a label is on the bottom, it is aligned with labels on axes that also have their label on the bottom and that have the same bottom-most subplot row. If the label is on the top, it is aligned with labels on axes with the same top-most row.

Parameters:
axslist of Axes

Optional list of (or ndarray) Axes to align the xlabels. Default is to align all axes on the figure.

See also

matplotlib.figure.Figure.align_ylabels
matplotlib.figure.Figure.align_labels

Notes

This assumes that axs are from the same GridSpec, so that their SubplotSpec positions correspond to figure positions.

Examples

Example with rotated xtick labels:

fig, axs = plt.subplots(1, 2)
for tick in axs[0].get_xticklabels():
    tick.set_rotation(55)
axs[0].set_xlabel('XLabel 0')
axs[1].set_xlabel('XLabel 1')
fig.align_xlabels()
align_ylabels(self, axs=None)[source]

Align the ylabels of subplots in the same subplot column if label alignment is being done automatically (i.e. the label position is not manually set).

Alignment persists for draw events after this is called.

If a label is on the left, it is aligned with labels on axes that also have their label on the left and that have the same left-most subplot column. If the label is on the right, it is aligned with labels on axes with the same right-most column.

Parameters:
axslist of Axes

Optional list (or ndarray) of Axes to align the ylabels. Default is to align all axes on the figure.

See also

matplotlib.figure.Figure.align_xlabels
matplotlib.figure.Figure.align_labels

Notes

This assumes that axs are from the same GridSpec, so that their SubplotSpec positions correspond to figure positions.

Examples

Example with large yticks labels:

fig, axs = plt.subplots(2, 1)
axs[0].plot(np.arange(0, 1000, 50))
axs[0].set_ylabel('YLabel 0')
axs[1].set_ylabel('YLabel 1')
fig.align_ylabels()
autofmt_xdate(self, bottom=0.2, rotation=30, ha='right', which='major')[source]

Date ticklabels often overlap, so it is useful to rotate them and right align them. Also, a common use case is a number of subplots with shared xaxes where the x-axis is date data. The ticklabels are often long, and it helps to rotate them on the bottom subplot and turn them off on other subplots, as well as turn off xlabels.

Parameters:
bottomfloat, default: 0.2

The bottom of the subplots for subplots_adjust.

rotationfloat, default: 30 degrees

The rotation angle of the xtick labels in degrees.

ha{'left', 'center', 'right'}, default: 'right'

The horizontal alignment of the xticklabels.

which{'major', 'minor', 'both'}, default: 'major'

Selects which ticklabels to rotate.
property axes

List of axes in the Figure. You can access and modify the axes in the Figure through this list.

Do not modify the list itself. Instead, use "add_axes, add_subplot or delaxes to add or remove an axes.

clear(self, keep_observers=False)[source]

Clear the figure -- synonym for clf.

clf(self, keep_observers=False)[source]

Clear the figure.

Set keep_observers to True if, for example, a gui widget is tracking the axes in the figure.

colorbar(self, mappable, cax=None, ax=None, use_gridspec=True, **kw)[source]

Create a colorbar for a ScalarMappable instance, mappable.

Documentation for the pyplot thin wrapper:

Add a colorbar to a plot.

Function signatures for the pyplot interface; all but the first are also method signatures for the colorbar method:

colorbar(**kwargs)
colorbar(mappable, **kwargs)
colorbar(mappable, cax=cax, **kwargs)
colorbar(mappable, ax=ax, **kwargs)
Parameters:
mappable

The matplotlib.cm.ScalarMappable (i.e., AxesImage, ContourSet, etc.) described by this colorbar. This argument is mandatory for the Figure.colorbar method but optional for the pyplot.colorbar function, which sets the default to the current image.

Note that one can create a ScalarMappable "on-the-fly" to generate colorbars not attached to a previously drawn artist, e.g.

fig.colorbar(cm.ScalarMappable(norm=norm, cmap=cmap), ax=ax)
caxAxes, optional

Axes into which the colorbar will be drawn.

axAxes, list of Axes, optional

Parent axes from which space for a new colorbar axes will be stolen. If a list of axes is given they will all be resized to make room for the colorbar axes.

use_gridspecbool, optional

If cax is None, a new cax is created as an instance of Axes. If ax is an instance of Subplot and use_gridspec is True, cax is created as an instance of Subplot using the gridspec module.
Returns:
colorbarColorbar

See also its base class, ColorbarBase.

Notes

Additional keyword arguments are of two kinds:

axes properties:

fractionfloat, default: 0.15
Fraction of original axes to use for colorbar.
shrinkfloat, default: 1.0
Fraction by which to multiply the size of the colorbar.
aspectfloat, default: 20
Ratio of long to short dimensions.
padfloat, default: 0.05 if vertical, 0.15 if horizontal
Fraction of original axes between colorbar and new image axes.
anchor(float, float), optional
The anchor point of the colorbar axes. Defaults to (0.0, 0.5) if vertical; (0.5, 1.0) if horizontal.
panchor(float, float), or False, optional
The anchor point of the colorbar parent axes. If False, the parent axes' anchor will be unchanged. Defaults to (1.0, 0.5) if vertical; (0.5, 0.0) if horizontal.

colorbar properties:

Property Description
extend {'neither', 'both', 'min', 'max'} If not 'neither', make pointed end(s) for out-of- range values. These are set for a given colormap using the colormap set_under and set_over methods.
extendfrac {None, 'auto', length, lengths} If set to None, both the minimum and maximum triangular colorbar extensions with have a length of 5% of the interior colorbar length (this is the default setting). If set to 'auto', makes the triangular colorbar extensions the same lengths as the interior boxes (when spacing is set to 'uniform') or the same lengths as the respective adjacent interior boxes (when spacing is set to 'proportional'). If a scalar, indicates the length of both the minimum and maximum triangular colorbar extensions as a fraction of the interior colorbar length. A two-element sequence of fractions may also be given, indicating the lengths of the minimum and maximum colorbar extensions respectively as a fraction of the interior colorbar length.
extendrect bool If False the minimum and maximum colorbar extensions will be triangular (the default). If True the extensions will be rectangular.
spacing {'uniform', 'proportional'} Uniform spacing gives each discrete color the same space; proportional makes the space proportional to the data interval.
ticks None or list of ticks or Locator If None, ticks are determined automatically from the input.
format None or str or Formatter If None, ScalarFormatter is used. If a format string is given, e.g., '%.3f', that is used. An alternative Formatter may be given instead.
drawedges bool Whether to draw lines at color boundaries.
label str The label on the colorbar's long axis.

The following will probably be useful only in the context of indexed colors (that is, when the mappable has norm=NoNorm()), or other unusual circumstances.

Property Description
boundaries None or a sequence
values None or a sequence which must be of length 1 less than the sequence of boundaries. For each region delimited by adjacent entries in boundaries, the color mapped to the corresponding value in values will be used.

If mappable is a ContourSet, its extend kwarg is included automatically.

The shrink kwarg provides a simple way to scale the colorbar with respect to the axes. Note that if cax is specified, it determines the size of the colorbar and shrink and aspect kwargs are ignored.

For more precise control, you can manually specify the positions of the axes objects in which the mappable and the colorbar are drawn. In this case, do not use any of the axes properties kwargs.

It is known that some vector graphics viewers (svg and pdf) renders white gaps between segments of the colorbar. This is due to bugs in the viewers, not Matplotlib. As a workaround, the colorbar can be rendered with overlapping segments:

cbar = colorbar()
cbar.solids.set_edgecolor("face")
draw()

However this has negative consequences in other circumstances, e.g. with semi-transparent images (alpha < 1) and colorbar extensions; therefore, this workaround is not used by default (see issue #1188).

contains(self, mouseevent)[source]

Test whether the mouse event occurred on the figure.

Returns:
bool, {}
delaxes(self, ax)[source]

Remove the Axes ax from the figure; update the current axes.

property dpi

The resolution in dots per inch.

draw(self, renderer)[source]

Draw the Artist (and its children) using the given renderer.

This has no effect if the artist is not visible (Artist.get_visible returns False).

Parameters:
rendererRendererBase subclass.

Notes

This method is overridden in the Artist subclasses.

draw_artist(self, a)[source]

Draw Artist instance a only.

This can only be called after the figure has been drawn.

execute_constrained_layout(self, renderer=None)[source]

Use layoutbox to determine pos positions within axes.

See also set_constrained_layout_pads.

figimage(self, X, xo=0, yo=0, alpha=None, norm=None, cmap=None, vmin=None, vmax=None, origin=None, resize=False, **kwargs)[source]

Add a non-resampled image to the figure.

The image is attached to the lower or upper left corner depending on origin.

Parameters:
X

The image data. This is an array of one of the following shapes:

  • MxN: luminance (grayscale) values
  • MxNx3: RGB values
  • MxNx4: RGBA values
xo, yoint

The x/y image offset in pixels.

alphaNone or float

The alpha blending value.

normmatplotlib.colors.Normalize

A Normalize instance to map the luminance to the interval [0, 1].

cmapstr or matplotlib.colors.Colormap, default: rcParams["image.cmap"] (default: 'viridis')

The colormap to use.

vmin, vmaxfloat

If norm is not given, these values set the data limits for the colormap.

origin{'upper', 'lower'}, default: rcParams["image.origin"] (default: 'upper')

Indicates where the [0, 0] index of the array is in the upper left or lower left corner of the axes.

resizebool

If True, resize the figure to match the given image size.
Returns:
matplotlib.image.FigureImage
Other Parameters:
**kwargs

Additional kwargs are Artist kwargs passed on to FigureImage.

Notes

figimage complements the axes image (imshow) which will be resampled to fit the current axes. If you want a resampled image to fill the entire figure, you can define an Axes with extent [0, 0, 1, 1].

Examples

f = plt.figure()
nx = int(f.get_figwidth() * f.dpi)
ny = int(f.get_figheight() * f.dpi)
data = np.random.random((ny, nx))
f.figimage(data)

get_tightbbox(self, renderer, bbox_extra_artists=None)[source]

Return a (tight) bounding box of the figure in inches.

Artists that have artist.set_in_layout(False) are not included in the bbox.

Parameters:
rendererRendererBase subclass

renderer that will be used to draw the figures (i.e. fig.canvas.get_renderer())

bbox_extra_artistslist of Artist or None

List of artists to include in the tight bounding box. If None (default), then all artist children of each axes are included in the tight bounding box.
Returns:
BboxBase

containing the bounding box (in figure inches).
get_window_extent(self, *args, **kwargs)[source]

Return the figure bounding box in display space. Arguments are ignored.

ginput(self, n=1, timeout=30, show_clicks=True, mouse_add=<MouseButton.LEFT: 1>, mouse_pop=<MouseButton.RIGHT: 3>, mouse_stop=<MouseButton.MIDDLE: 2>)[source]

Blocking call to interact with a figure.

Wait until the user clicks n times on the figure, and return the coordinates of each click in a list.

There are three possible interactions:

  • Add a point.
  • Remove the most recently added point.
  • Stop the interaction and return the points added so far.

The actions are assigned to mouse buttons via the arguments mouse_add, mouse_pop and mouse_stop.

Parameters:
nint, default: 1

Number of mouse clicks to accumulate. If negative, accumulate clicks until the input is terminated manually.

timeoutfloat, default: 30 seconds

Number of seconds to wait before timing out. If zero or negative will never timeout.

show_clicksbool, default: True

If True, show a red cross at the location of each click.

mouse_addMouseButton or None, default: MouseButton.LEFT

Mouse button used to add points.

mouse_popMouseButton or None, default: MouseButton.RIGHT

Mouse button used to remove the most recently added point.

mouse_stopMouseButton or None, default: MouseButton.MIDDLE

Mouse button used to stop input.
Returns:
list of tuples

A list of the clicked (x, y) coordinates.

Notes

The keyboard can also be used to select points in case your mouse does not have one or more of the buttons. The delete and backspace keys act like right clicking (i.e., remove last point), the enter key terminates input and any other key (not already used by the window manager) selects a point.

init_layoutbox(self)[source]

Initialize the layoutbox for use in constrained_layout.

legend(self, *args, **kwargs)[source]

Place a legend on the figure.

To make a legend from existing artists on every axes:

legend()

To make a legend for a list of lines and labels:

legend(
    (line1, line2, line3),
    ('label1', 'label2', 'label3'),
    loc='upper right')

These can also be specified by keyword:

legend(
    handles=(line1, line2, line3),
    labels=('label1', 'label2', 'label3'),
    loc='upper right')
Parameters:
handleslist of Artist, optional

A list of Artists (lines, patches) to be added to the legend. Use this together with labels, if you need full control on what is shown in the legend and the automatic mechanism described above is not sufficient.

The length of handles and labels should be the same in this case. If they are not, they are truncated to the smaller length.

labelslist of str, optional

A list of labels to show next to the artists. Use this together with handles, if you need full control on what is shown in the legend and the automatic mechanism described above is not sufficient.
Returns:
Legend
Other Parameters:
locstr or pair of floats, default: rcParams["legend.loc"] (default: 'best') ('best' for axes, 'upper right' for figures)

The location of the legend.

The strings 'upper left', 'upper right', 'lower left', 'lower right' place the legend at the corresponding corner of the axes/figure.

The strings 'upper center', 'lower center', 'center left', 'center right' place the legend at the center of the corresponding edge of the axes/figure.

The string 'center' places the legend at the center of the axes/figure.

The string 'best' places the legend at the location, among the nine locations defined so far, with the minimum overlap with other drawn artists. This option can be quite slow for plots with large amounts of data; your plotting speed may benefit from providing a specific location.

The location can also be a 2-tuple giving the coordinates of the lower-left corner of the legend in axes coordinates (in which case bbox_to_anchor will be ignored).

For back-compatibility, 'center right' (but no other location) can also be spelled 'right', and each "string" locations can also be given as a numeric value:

Location String Location Code
'best' 0
'upper right' 1
'upper left' 2
'lower left' 3
'lower right' 4
'right' 5
'center left' 6
'center right' 7
'lower center' 8
'upper center' 9
'center' 10
bbox_to_anchorBboxBase, 2-tuple, or 4-tuple of floats

Box that is used to position the legend in conjunction with loc. Defaults to axes.bbox (if called as a method to Axes.legend) or figure.bbox (if Figure.legend). This argument allows arbitrary placement of the legend.

Bbox coordinates are interpreted in the coordinate system given by bbox_transform, with the default transform Axes or Figure coordinates, depending on which legend is called.

If a 4-tuple or BboxBase is given, then it specifies the bbox (x, y, width, height) that the legend is placed in. To put the legend in the best location in the bottom right quadrant of the axes (or figure):

loc='best', bbox_to_anchor=(0.5, 0., 0.5, 0.5)

A 2-tuple (x, y) places the corner of the legend specified by loc at x, y. For example, to put the legend's upper right-hand corner in the center of the axes (or figure) the following keywords can be used:

loc='upper right', bbox_to_anchor=(0.5, 0.5)
ncolint, default: 1

The number of columns that the legend has.

propNone or matplotlib.font_manager.FontProperties or dict

The font properties of the legend. If None (default), the current matplotlib.rcParams will be used.

fontsizeint or {'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', 'xx-large'}

The font size of the legend. If the value is numeric the size will be the absolute font size in points. String values are relative to the current default font size. This argument is only used if prop is not specified.

labelcolorstr or list

Sets the color of the text in the legend. Can be a valid color string (for example, 'red'), or a list of color strings. The labelcolor can also be made to match the color of the line or marker using 'linecolor', 'markerfacecolor' (or 'mfc'), or 'markeredgecolor' (or 'mec').

numpointsint, default: rcParams["legend.numpoints"] (default: 1)

The number of marker points in the legend when creating a legend entry for a Line2D (line).

scatterpointsint, default: rcParams["legend.scatterpoints"] (default: 1)

The number of marker points in the legend when creating a legend entry for a PathCollection (scatter plot).

scatteryoffsetsiterable of floats, default: [0.375, 0.5, 0.3125]

The vertical offset (relative to the font size) for the markers created for a scatter plot legend entry. 0.0 is at the base the legend text, and 1.0 is at the top. To draw all markers at the same height, set to [0.5].

markerscalefloat, default: rcParams["legend.markerscale"] (default: 1.0)

The relative size of legend markers compared with the originally drawn ones.

markerfirstbool, default: True

If True, legend marker is placed to the left of the legend label. If False, legend marker is placed to the right of the legend label.

facecolor"inherit" or color, default: rcParams["legend.facecolor"] (default: 'inherit')

The legend's background color. If "inherit", use rcParams["axes.facecolor"] (default: 'white').

edgecolor"inherit" or color, default: rcParams["legend.edgecolor"] (default: '0.8')

The legend's background patch edge color. If "inherit", use take rcParams["axes.edgecolor"] (default: 'black').

mode{"expand", None}

If mode is set to "expand" the legend will be horizontally expanded to fill the axes area (or bbox_to_anchor if defines the legend's size).

bbox_transformNone or matplotlib.transforms.Transform

The transform for the bounding box (bbox_to_anchor). For a value of None (default) the Axes' transAxes transform will be used.

titlestr or None

The legend's title. Default is no title (None).

savefig(self, fname, *, transparent=None, **kwargs)[source]

Save the current figure.

Call signature:

savefig(fname, dpi=None, facecolor='w', edgecolor='w',
        orientation='portrait', papertype=None, format=None,
        transparent=False, bbox_inches=None, pad_inches=0.1,
        frameon=None, metadata=None)

The available output formats depend on the backend being used.

Parameters:
fnamestr or path-like or file-like

A path, or a Python file-like object, or possibly some backend-dependent object such as matplotlib.backends.backend_pdf.PdfPages.

If format is set, it determines the output format, and the file is saved as fname. Note that fname is used verbatim, and there is no attempt to make the extension, if any, of fname match format, and no extension is appended.

If format is not set, then the format is inferred from the extension of fname, if there is one. If format is not set and fname has no extension, then the file is saved with rcParams["savefig.format"] (default: 'png') and the appropriate extension is appended to fname.
Other Parameters:
dpifloat or 'figure', default: rcParams["savefig.dpi"] (default: 'figure')

The resolution in dots per inch. If 'figure', use the figure's dpi value.

qualityint, default: rcParams["savefig.jpeg_quality"] (default: 95)

Applicable only if format is 'jpg' or 'jpeg', ignored otherwise.

The image quality, on a scale from 1 (worst) to 95 (best). Values above 95 should be avoided; 100 disables portions of the JPEG compression algorithm, and results in large files with hardly any gain in image quality.

This parameter is deprecated.

optimizebool, default: False

Applicable only if format is 'jpg' or 'jpeg', ignored otherwise.

Whether the encoder should make an extra pass over the image in order to select optimal encoder settings.

This parameter is deprecated.

progressivebool, default: False

Applicable only if format is 'jpg' or 'jpeg', ignored otherwise.

Whether the image should be stored as a progressive JPEG file.

This parameter is deprecated.

facecolorcolor or 'auto', default: rcParams["savefig.facecolor"] (default: 'auto')

The facecolor of the figure. If 'auto', use the current figure facecolor.

edgecolorcolor or 'auto', default: rcParams["savefig.edgecolor"] (default: 'auto')

The edgecolor of the figure. If 'auto', use the current figure edgecolor.

orientation{'landscape', 'portrait'}

Currently only supported by the postscript backend.

papertypestr

One of 'letter', 'legal', 'executive', 'ledger', 'a0' through 'a10', 'b0' through 'b10'. Only supported for postscript output.

formatstr

The file format, e.g. 'png', 'pdf', 'svg', ... The behavior when this is unset is documented under fname.

transparentbool

If True, the axes patches will all be transparent; the figure patch will also be transparent unless facecolor and/or edgecolor are specified via kwargs. This is useful, for example, for displaying a plot on top of a colored background on a web page. The transparency of these patches will be restored to their original values upon exit of this function.

bbox_inchesstr or Bbox, default: rcParams["savefig.bbox"] (default: None)

Bounding box in inches: only the given portion of the figure is saved. If 'tight', try to figure out the tight bbox of the figure.

pad_inchesfloat, default: rcParams["savefig.pad_inches"] (default: 0.1)

Amount of padding around the figure when bbox_inches is 'tight'.

bbox_extra_artistslist of Artist, optional

A list of extra artists that will be considered when the tight bbox is calculated.

backendstr, optional

Use a non-default backend to render the file, e.g. to render a png file with the "cairo" backend rather than the default "agg", or a pdf file with the "pgf" backend rather than the default "pdf". Note that the default backend is normally sufficient. See The builtin backends for a list of valid backends for each file format. Custom backends can be referenced as "module://...".

metadatadict, optional

Key/value pairs to store in the image metadata. The supported keys and defaults depend on the image format and backend:

  • 'png' with Agg backend: See the parameter metadata of print_png.
  • 'pdf' with pdf backend: See the parameter metadata of PdfPages.
  • 'svg' with svg backend: See the parameter metadata of print_svg.
  • 'eps' and 'ps' with PS backend: Only 'Creator' is supported.

Parameters:
canvasFigureCanvas
set_constrained_layout(self, constrained)[source]

Set whether constrained_layout is used upon drawing. If None, rcParams["figure.constrained_layout.use"] (default: False) value will be used.

When providing a dict containing the keys w_pad, h_pad the default constrained_layout paddings will be overridden. These pads are in inches and default to 3.0/72.0. w_pad is the width padding and h_pad is the height padding.

See Constrained Layout Guide.

See also

matplotlib.figure.Figure.set_figheight
matplotlib.figure.Figure.set_size_inches
set_frameon(self, b)[source]

See also

matplotlib.figure.Figure.get_size_inches
matplotlib.figure.Figure.set_figwidth
matplotlib.figure.Figure.set_figheight

Notes

To transform from pixels to inches divide by Figure.dpi.

set_tight_layout(self, tight)[source]

Set whether and how tight_layout is called when drawing.

Parameters:
tightbool or dict with keys "pad", "w_pad", "h_pad", "rect" or None

If a bool, sets whether to call tight_layout upon drawing. If None, use the figure.autolayout rcparam instead. If a dict, pass it as kwargs to tight_layout, overriding the default paddings.
show(self, warn=True)[source]

If using a GUI backend with pyplot, display the figure window.

If the figure was not created using figure, it will lack a FigureManagerBase, and this method will raise an AttributeError.

Warning

This does not manage an GUI event loop. Consequently, the figure may only be shown briefly or not shown at all if you or your environment are not managing an event loop.

Proper use cases for Figure.show include running this from a GUI application or an IPython shell.

If you're running a pure python shell or executing a non-GUI python script, you should use matplotlib.pyplot.show instead, which takes care of managing the event loop for you.

Parameters:
warnbool, default: True

If True and we are not running headless (i.e. on Linux with an unset DISPLAY), issue warning when called on a non-GUI backend.
subplot_mosaic(self, layout, *, subplot_kw=None, gridspec_kw=None, empty_sentinel='.')[source]

Build a layout of Axes based on ASCII art or nested lists.

This is a helper function to build complex GridSpec layouts visually.

Note

This API is provisional and may be revised in the future based on early user feedback.

Parameters:
layoutlist of list of {hashable or nested} or str

A visual layout of how you want your Axes to be arranged labeled as strings. For example

x = [['A panel', 'A panel', 'edge'],
     ['C panel', '.',       'edge']]

Produces 4 axes:

  • 'A panel' which is 1 row high and spans the first two columns
  • 'edge' which is 2 rows high and is on the right edge
  • 'C panel' which in 1 row and 1 column wide in the bottom left
  • a blank space 1 row and 1 column wide in the bottom center

Any of the entries in the layout can be a list of lists of the same form to create nested layouts.

If input is a str, then it must be of the form

'''
AAE
C.E
'''

where each character is a column and each line is a row. This only allows only single character Axes labels and does not allow nesting but is very terse.

subplot_kwdict, optional

Dictionary with keywords passed to the Figure.add_subplot call used to create each subplot.

gridspec_kwdict, optional

Dictionary with keywords passed to the GridSpec constructor used to create the grid the subplots are placed on.

empty_sentinelobject, optional

Entry in the layout to mean "leave this space empty". Defaults to '.'. Note, if layout is a string, it is processed via inspect.cleandoc to remove leading white space, which may interfere with using white-space as the empty sentinel.
Returns:
dict[label, Axes]

A dictionary mapping the labels to the Axes objects.
subplots(self, nrows=1, ncols=1, *, sharex=False, sharey=False, squeeze=True, subplot_kw=None, gridspec_kw=None)[source]

Add a set of subplots to this figure.

This utility wrapper makes it convenient to create common layouts of subplots in a single call.

Parameters:
nrows, ncolsint, default: 1

Number of rows/columns of the subplot grid.

sharex, shareybool 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 created. Similarly, when subplots have a shared y-axis along a row, only the y tick labels of the first column subplot are created. To later turn other subplots' ticklabels on, use tick_params.

squeezebool, default: True
  • If True, extra dimensions are squeezed out from the returned array of Axes:
    • if only one subplot is constructed (nrows=ncols=1), the resulting single Axes object is returned as a scalar.
    • for Nx1 or 1xM subplots, the returned object is a 1D numpy object array of Axes objects.
    • for NxM, subplots with N>1 and M>1 are returned as a 2D array.
  • 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_kwdict, optional

Dict with keywords passed to the Figure.add_subplot call used to create each subplot.

gridspec_kwdict, optional

Dict with keywords passed to the GridSpec constructor used to create the grid the subplots are placed on.
Returns:
Axes or array of Axes

Either a single 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.
