classmatplotlib.figure.FigureBase(**kwargs)[source]
 
Base class for figure.Figure and figure.SubFigure containing the methods that add artists to the figure or subfigure, create Axes, etc.   add_artist(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.transSubfigure.  
clipbool, default: False


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

The added artist.     
   add_axes(*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'.  
axes_classsubclass type of Axes, optional


The axes.Axes subclass that is instantiated. This parameter is incompatible with projection and polar. See axisartist for examples.  
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.

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.

   align_labels(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(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(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(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 x-axis 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.     
   propertyaxes
 
The Axes instance the artist resides in, or None. 
   colorbar(mappable, cax=None, ax=None, use_gridspec=True, **kw)[source]
 
Add a colorbar to a plot.  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


One or more parent axes from which space for a new colorbar axes will be stolen, if cax is None. This has no effect if cax is set.  
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

   Notes Additional keyword arguments are of two kinds: axes properties:  locationNone or {'left', 'right', 'top', 'bottom'}


The location, relative to the parent axes, where the colorbar axes is created. It also determines the orientation of the colorbar (colorbars on the left and right are vertical, colorbars at the top and bottom are horizontal). If None, the location will come from the orientation if it is set (vertical colorbars on the right, horizontal ones at the bottom), or default to 'right' if orientation is unset.  orientationNone or {'vertical', 'horizontal'}


The orientation of the colorbar. It is preferable to set the location of the colorbar, as that also determines the orientation; passing incompatible values for location and orientation raises an exception.  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 colormapped 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(mouseevent)[source]
 
Test whether the mouse event occurred on the figure.  Returns 
 bool, {}
   
   convert_xunits(x)[source]
 
Convert x using the unit type of the xaxis. If the artist is not in contained in an Axes or if the xaxis does not have units, x itself is returned. 
   convert_yunits(y)[source]
 
Convert y using the unit type of the yaxis. If the artist is not in contained in an Axes or if the yaxis does not have units, y itself is returned. 
   delaxes(ax)[source]
 
Remove the Axes ax from the figure; update the current Axes. 
   draw(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. 
   findobj(match=None, include_self=True)[source]
 
Find artist objects. Recursively find all Artist instances contained in the artist.  Parameters 
 match

A filter criterion for the matches. This can be  
None: Return all objects contained in artist. A function with signature def match(artist: Artist) -> bool. The result will only contain artists for which the function returns True. A class instance: e.g., Line2D. The result will only contain artists of this class or its subclasses (isinstance check).   
include_selfbool


Include self in the list to be checked for a match.    Returns 
 list of Artist

   
   format_cursor_data(data)[source]
 
Return a string representation of data.  Note This method is intended to be overridden by artist subclasses. As an end-user of Matplotlib you will most likely not call this method yourself.  The default implementation converts ints and floats and arrays of ints and floats into a comma-separated string enclosed in square brackets, unless the artist has an associated colorbar, in which case scalar values are formatted using the colorbar's formatter.  See also  get_cursor_data
  
   propertyframeon
 
Return the figure's background patch visibility, i.e. whether the figure background will be drawn. Equivalent to Figure.patch.get_visible(). 
   gca(**kwargs)[source]
 
Get the current Axes. If there is currently no Axes on this Figure, a new one is created using Figure.add_subplot. (To test whether there is currently an Axes on a Figure, check whether figure.axes is empty. To test whether there is currently a Figure on the pyplot figure stack, check whether pyplot.get_fignums() is empty.) The following kwargs are supported for ensuring the returned Axes adheres to the given projection etc., and for Axes creation if the active Axes does not exist:

   get_cursor_data(event)[source]
 
Return the cursor data for a given event.  Note This method is intended to be overridden by artist subclasses. As an end-user of Matplotlib you will most likely not call this method yourself.  Cursor data can be used by Artists to provide additional context information for a given event. The default implementation just returns None. Subclasses can override the method and return arbitrary data. However, when doing so, they must ensure that format_cursor_data can convert the data to a string representation. The only current use case is displaying the z-value of an AxesImage in the status bar of a plot window, while moving the mouse.  Parameters

   get_window_extent(*args, **kwargs)[source]
 
Get the artist's bounding box in display space. The bounding box' width and height are nonnegative. Subclasses should override for inclusion in the bounding box "tight" calculation. Default is to return an empty bounding box at 0, 0. Be careful when using this function, the results will not update if the artist window extent of the artist changes. The extent can change due to any changes in the transform stack, such as changing the axes limits, the figure size, or the canvas used (as is done when saving a figure). This can lead to unexpected behavior where interactive figures will look fine on the screen, but will save incorrectly. 
   get_zorder()[source]
 
Return the artist's zorder. 
   have_units()[source]
 
Return whether units are set on any axis. 
   is_transform_set()[source]
 
Return whether the Artist has an explicitly set transform. This is True after set_transform has been called. 
   legend(*args, **kwargs)[source]
 
Place a legend on the figure. Call signatures: legend()
legend(handles, labels)
legend(handles=handles)
legend(labels)
 The call signatures correspond to the following different ways to use this method: 1. Automatic detection of elements to be shown in the legend The elements to be added to the legend are automatically determined, when you do not pass in any extra arguments. In this case, the labels are taken from the artist. You can specify them either at artist creation or by calling the set_label() method on the artist: ax.plot([1, 2, 3], label='Inline label')
fig.legend()
 or: line, = ax.plot([1, 2, 3])
line.set_label('Label via method')
fig.legend()
 Specific lines can be excluded from the automatic legend element selection by defining a label starting with an underscore. This is default for all artists, so calling Figure.legend without any arguments and without setting the labels manually will result in no legend being drawn. 2. Explicitly listing the artists and labels in the legend For full control of which artists have a legend entry, it is possible to pass an iterable of legend artists followed by an iterable of legend labels respectively: fig.legend([line1, line2, line3], ['label1', 'label2', 'label3'])
 3. Explicitly listing the artists in the legend This is similar to 2, but the labels are taken from the artists' label properties. Example: line1, = ax1.plot([1, 2, 3], label='label1')
line2, = ax2.plot([1, 2, 3], label='label2')
fig.legend(handles=[line1, line2])
 4. Labeling existing plot elements  Discouraged This call signature is discouraged, because the relation between plot elements and labels is only implicit by their order and can easily be mixed up.  To make a legend for all artists on all Axes, call this function with an iterable of strings, one for each legend item. For example: fig, (ax1, ax2)  = plt.subplots(1, 2)
ax1.plot([1, 3, 5], color='blue')
ax2.plot([2, 4, 6], color='red')
fig.legend(['the blues', 'the reds'])
  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)

The alpha transparency of the legend's background. If shadow is activated and framealpha is None, the default value is ignored.  
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

Set the alpha value used for blending - not supported on all backends.  Parameters 
 
alphascalar or None


alpha must be within the 0-1 range, inclusive.     
   set_animated(b)[source]
 
Set whether the artist is intended to be used in an animation. If True, the artist is excluded from regular drawing of the figure. You have to call Figure.draw_artist / Axes.draw_artist explicitly on the artist. This appoach is used to speed up animations using blitting. See also matplotlib.animation and Faster rendering by using blitting.  Parameters 
 
bbool

   
   set_clip_box(clipbox)[source]
 
Set the artist's clip Bbox.  Parameters 
 
clipboxBbox

   
   set_clip_on(b)[source]
 
Set whether the artist uses clipping. When False artists will be visible outside of the axes which can lead to unexpected results.  Parameters 
 
bbool

   
   set_clip_path(path, transform=None)[source]
 
Set the artist's clip path.  Parameters 
 
pathPatch or Path or TransformedPath or None


The clip path. If given a Path, transform must be provided as well. If None, a previously set clip path is removed.  
transformTransform, optional


Only used if path is a Path, in which case the given Path is converted to a TransformedPath using transform.     Notes For efficiency, if path is a Rectangle this method will set the clipping box to the corresponding rectangle and set the clipping path to None. For technical reasons (support of set), a tuple (path, transform) is also accepted as a single positional parameter. 
   set_edgecolor(color)[source]
 
Set the edge color of the Figure rectangle.  Parameters 
 
colorcolor

   
   set_facecolor(color)[source]
 
Set the face color of the Figure rectangle.  Parameters 
 
colorcolor

   
   set_figure(fig)[source]
 
Set the Figure instance the artist belongs to.  Parameters 
 
figFigure

   
   set_frameon(b)[source]
 
Set the figure's background patch visibility, i.e. whether the figure background will be drawn. Equivalent to Figure.patch.set_visible().  Parameters 
 
bbool

   
   set_gid(gid)[source]
 
Set the (group) id for the artist.  Parameters 
 
gidstr

   
   set_in_layout(in_layout)[source]

in_layoutbool

   
   set_label(s)[source]
 
Set a label that will be displayed in the legend.  Parameters 
 
sobject


s will be converted to a string by calling str.     
   set_linewidth(linewidth)[source]
 
Set the line width of the Figure rectangle.  Parameters 
 
linewidthnumber

   
   set_path_effects(path_effects)[source]
 
Set the path effects.  Parameters 
 
path_effectsAbstractPathEffect

   
   set_picker(picker)[source]
 
Define the picking behavior of the artist.  Parameters 
 
pickerNone or bool or float or callable


This can be one of the following:  
None: Picking is disabled for this artist (default). A boolean: If True then picking will be enabled and the artist will fire a pick event if the mouse event is over the artist. A float: If picker is a number it is interpreted as an epsilon tolerance in points and the artist will fire off an event if its data is within epsilon of the mouse event. For some artists like lines and patch collections, the artist may provide additional data to the pick event that is generated, e.g., the indices of the data within epsilon of the pick event 
A function: If picker is callable, it is a user supplied function which determines whether the artist is hit by the mouse event: hit, props = picker(artist, mouseevent)
 to determine the hit test. if the mouse event is over the artist, return hit=True and props is a dictionary of properties you want added to the PickEvent attributes.       
   set_rasterized(rasterized)[source]
 
Force rasterized (bitmap) drawing for vector graphics output. Rasterized drawing is not supported by all artists. If you try to enable this on an artist that does not support it, the command has no effect and a warning will be issued. This setting is ignored for pixel-based output. See also Rasterization for vector graphics.  Parameters 
 
rasterizedbool

   
   set_sketch_params(scale=None, length=None, randomness=None)[source]
 
Set the sketch parameters.  Parameters 
 
scalefloat, optional


The amplitude of the wiggle perpendicular to the source line, in pixels. If scale is None, or not provided, no sketch filter will be provided.  
lengthfloat, optional


The length of the wiggle along the line, in pixels (default 128.0)  
randomnessfloat, optional


The scale factor by which the length is shrunken or expanded (default 16.0) The PGF backend uses this argument as an RNG seed and not as described above. Using the same seed yields the same random shape.     
   set_snap(snap)[source]
 
Set the snapping behavior. Snapping aligns positions with the pixel grid, which results in clearer images. For example, if a black line of 1px width was defined at a position in between two pixels, the resulting image would contain the interpolated value of that line in the pixel grid, which would be a grey value on both adjacent pixel positions. In contrast, snapping will move the line to the nearest integer pixel value, so that the resulting image will really contain a 1px wide black line. Snapping is currently only supported by the Agg and MacOSX backends.  Parameters 
 
snapbool or None


Possible values:  
True: Snap vertices to the nearest pixel center. 
False: Do not modify vertex positions. 
None: (auto) If the path contains only rectilinear line segments, round to the nearest pixel center.      
   set_transform(t)[source]
 
Set the artist transform.  Parameters 
 
tTransform

   
   set_url(url)[source]
 
Set the url for the artist.  Parameters 
 
urlstr

   
   set_visible(b)[source]
 
Set the artist's visibility.  Parameters 
 
bbool

   
   set_zorder(level)[source]
 
Set the zorder for the artist. Artists with lower zorder values are drawn first.  Parameters 
 
levelfloat

   
   propertystale
 
Whether the artist is 'stale' and needs to be re-drawn for the output to match the internal state of the artist. 
   propertysticky_edges
 
x and y sticky edge lists for autoscaling. When performing autoscaling, if a data limit coincides with a value in the corresponding sticky_edges list, then no margin will be added--the view limit "sticks" to the edge. A typical use case is histograms, where one usually expects no margin on the bottom edge (0) of the histogram. Moreover, margin expansion "bumps" against sticky edges and cannot cross them. For example, if the upper data limit is 1.0, the upper view limit computed by simple margin application is 1.2, but there is a sticky edge at 1.1, then the actual upper view limit will be 1.1. This attribute cannot be assigned to; however, the x and y lists can be modified in place as needed. Examples >>> artist.sticky_edges.x[:] = (xmin, xmax)
>>> artist.sticky_edges.y[:] = (ymin, ymax)
 
   subfigures(nrows=1, ncols=1, squeeze=True, wspace=None, hspace=None, width_ratios=None, height_ratios=None, **kwargs)[source]
 
Add a subfigure to this figure or subfigure. A subfigure has the same artist methods as a figure, and is logically the same as a figure, but cannot print itself. See Figure subfigures.  Parameters 
 
nrows, ncolsint, default: 1


Number of rows/columns of the subfigure grid.  
squeezebool, default: True


If True, extra dimensions are squeezed out from the returned array of subfigures.  
wspace, hspacefloat, default: None


The amount of width/height reserved for space between subfigures, expressed as a fraction of the average subfigure width/height. If not given, the values will be inferred from a figure or rcParams when necessary.  
width_ratiosarray-like of length ncols, optional


Defines the relative widths of the columns. Each column gets a relative width of width_ratios[i] / sum(width_ratios). If not given, all columns will have the same width.  
height_ratiosarray-like of length nrows, optional


Defines the relative heights of the rows. Each row gets a relative height of height_ratios[i] / sum(height_ratios). If not given, all rows will have the same height.     
   subplot_mosaic(mosaic, *, sharex=False, sharey=False, 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 
 
mosaiclist 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 can either be a multi-line string of the form '''
AAE
C.E
'''
 where each character is a column and each line is a row. Or it can be a single-line string where rows are separated by ;: 'AB;CC'
 The string notation allows only single character Axes labels and does not support nesting but is very terse.  
sharex, shareybool, default: False


If True, the x-axis (sharex) or y-axis (sharey) will be shared among all subplots. In that case, tick label visibility and axis units behave as for subplots. If False, each subplot's x- or y-axis will be independent.  
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. The order of the axes is left-to-right and top-to-bottom of their position in the total layout.     
   subplots(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 x-axis (sharex) or y-axis (sharey):  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. When subplots have a shared axis that has units, calling Axis.set_units will update each axis with the new units.  
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.      See also  pyplot.subplots
Figure.add_subplot
