# mpl_toolkits.mplot3d.axes3d.Axes3D¶

class mpl_toolkits.mplot3d.axes3d.Axes3D(fig, rect=None, *args, azim=- 60, elev=30, sharez=None, proj_type='persp', box_aspect=None, **kwargs)[source]

Bases: matplotlib.axes._axes.Axes

3D axes object.

Parameters:
figFigure

The parent figure.

rect(float, float, float, float)

The (left, bottom, width, height) axes position.

azimfloat, default: -60

Azimuthal viewing angle.

elevfloat, default: 30

Elevation viewing angle.

sharezAxes3D, optional

Other axes to share z-limits with.

proj_type{'persp', 'ortho'}

add_collection3d(self, col, zs=0, zdir='z')[source]

Add a 3D collection object to the plot.

2D collection types are converted to a 3D version by modifying the object and adding z coordinate information.

Supported are:

• PolyCollection
• LineCollection
• PatchCollection
add_contour_set(self, cset, extend3d=False, stride=5, zdir='z', offset=None)[source]
add_contourf_set(self, cset, zdir='z', offset=None)[source]
apply_aspect(self, position=None)[source]

Adjust the Axes for a specified data aspect ratio.

Depending on get_adjustable this will modify either the Axes box (position) or the view limits. In the former case, get_anchor will affect the position.

matplotlib.axes.Axes.set_aspect
For a description of aspect ratio handling.
matplotlib.axes.Axes.set_adjustable
Set how the Axes adjusts to achieve the required aspect ratio.
matplotlib.axes.Axes.set_anchor
Set the position in case of extra space.

Notes

This is called automatically when each Axes is drawn. You may need to call it yourself if you need to update the Axes position and/or view limits before the Figure is drawn.

auto_scale_xyz(self, X, Y, Z=None, had_data=None)[source]
autoscale(self, enable=True, axis='both', tight=None)[source]

Convenience method for simple axis view autoscaling. See matplotlib.axes.Axes.autoscale() for full explanation. Note that this function behaves the same, but for all three axes. Therefore, 'z' can be passed for axis, and 'both' applies to all three axes.

New in version 1.1.0.

autoscale_view(self, tight=None, scalex=True, scaley=True, scalez=True)[source]

Autoscale the view limits using the data limits. See matplotlib.axes.Axes.autoscale_view() for documentation. Note that this function applies to the 3D axes, and as such adds the scalez to the function arguments.

Changed in version 1.1.0: Function signature was changed to better match the 2D version. tight is now explicitly a kwarg and placed first.

Changed in version 1.2.1: This is now fully functional.

bar(self, left, height, zs=0, zdir='z', *args, **kwargs)[source]

Parameters: left1D array-likeThe x coordinates of the left sides of the bars. height1D array-likeThe height of the bars. zsfloat or 1D array-likeZ coordinate of bars; if a single value is specified, it will be used for all bars. zdir{'x', 'y', 'z'}, default: 'z'When plotting 2D data, the direction to use as z ('x', 'y' or 'z'). **kwargsOther arguments are forwarded to matplotlib.axes.Axes.bar. mpl_toolkits.mplot3d.art3d.Patch3DCollection

disable_mouse_rotation(self)[source]

Disable mouse buttons for 3D rotation and zooming.

draw(self, renderer)[source]

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

Parameters: rendererRendererBase subclass.

Notes

This method is overridden in the Artist subclasses.

errorbar(self, x, y, z, zerr=None, yerr=None, xerr=None, fmt='', barsabove=False, errorevery=1, ecolor=None, elinewidth=None, capsize=None, capthick=None, xlolims=False, xuplims=False, ylolims=False, yuplims=False, zlolims=False, zuplims=False, **kwargs)[source]

Plot lines and/or markers with errorbars around them.

x/y/z define the data locations, and xerr/yerr/zerr define the errorbar sizes. By default, this draws the data markers/lines as well the errorbars. Use fmt='none' to draw errorbars only.

Parameters: x, y, zfloat or array-likeThe data positions. xerr, yerr, zerrfloat or array-like, shape (N,) or (2, N), optionalThe errorbar sizes: scalar: Symmetric +/- values for all data points. shape(N,): Symmetric +/-values for each data point. shape(2, N): Separate - and + values for each bar. First row contains the lower errors, the second row contains the upper errors. None: No errorbar. Note that all error arrays should have positive values. fmtstr, default: ''The format for the data points / data lines. See plot for details. Use 'none' (case insensitive) to plot errorbars without any data markers. ecolorcolor, default: NoneThe color of the errorbar lines. If None, use the color of the line connecting the markers. elinewidthfloat, default: NoneThe linewidth of the errorbar lines. If None, the linewidth of the current style is used. capsizefloat, default: rcParams["errorbar.capsize"] (default: 0.0)The length of the error bar caps in points. capthickfloat, default: NoneAn alias to the keyword argument markeredgewidth (a.k.a. mew). This setting is a more sensible name for the property that controls the thickness of the error bar cap in points. For backwards compatibility, if mew or markeredgewidth are given, then they will over-ride capthick. This may change in future releases. barsabovebool, default: FalseIf True, will plot the errorbars above the plot symbols. Default is below. xlolims, ylolims, zlolimsbool, default: FalseThese arguments can be used to indicate that a value gives only lower limits. In that case a caret symbol is used to indicate this. lims-arguments may be scalars, or array-likes of the same length as the errors. To use limits with inverted axes, set_xlim or set_ylim must be called before errorbar(). Note the tricky parameter names: setting e.g. ylolims to True means that the y-value is a lower limit of the True value, so, only an upward-pointing arrow will be drawn! xuplims, yuplims, zuplimsbool, default: FalseSame as above, but for controlling the upper limits. erroreveryint or (int, int), default: 1draws error bars on a subset of the data. errorevery =N draws error bars on the points (x[::N], y[::N], z[::N]). errorevery =(start, N) draws error bars on the points (x[start::N], y[start::N], z[start::N]). e.g. errorevery=(6, 3) adds error bars to the data at (x[6], x[9], x[12], x[15], ...). Used to avoid overlapping error bars when two series share x-axis values. errlineslistList of Line3DCollection instances each containing an errorbar line. caplineslistList of Line3D instances each containing a capline object. limmarkslistList of Line3D instances each containing a marker with an upper or lower limit. **kwargsAll other keyword arguments for styling errorbar lines are passed Line3DCollection.

Examples

format_coord(self, xd, yd)[source]

get_zticks(self, *, minor=False)

Return the zaxis' tick locations in data coordinates.

grid(self, b=True, **kwargs)[source]

Currently, this function does not behave the same as matplotlib.axes.Axes.grid(), but it is intended to eventually support that behavior.

New in version 1.1.0.

invert_zaxis(self)[source]

Invert the z-axis.

New in version 1.1.0: This function was added, but not tested. Please report any bugs.

locator_params(self, axis='both', tight=None, **kwargs)[source]

Convenience method for controlling tick locators.

See matplotlib.axes.Axes.locator_params() for full documentation. Note that this is for Axes3D objects, therefore, setting axis to 'both' will result in the parameters being set for all three axes. Also, axis can also take a value of 'z' to apply parameters to the z axis.

New in version 1.1.0: This function was added, but not tested. Please report any bugs.

margins(self, *margins, x=None, y=None, z=None, tight=True)[source]

Convenience method to set or retrieve autoscaling margins.

Call signatures:

margins()


returns xmargin, ymargin, zmargin

margins(margin)

margins(xmargin, ymargin, zmargin)

margins(x=xmargin, y=ymargin, z=zmargin)

margins(..., tight=False)


All forms above set the xmargin, ymargin and zmargin parameters. All keyword parameters are optional. A single positional argument specifies xmargin, ymargin and zmargin. Passing both positional and keyword arguments for xmargin, ymargin, and/or zmargin is invalid.

The tight parameter is passed to autoscale_view(), which is executed after a margin is changed; the default here is True, on the assumption that when margins are specified, no additional padding to match tick marks is usually desired. Setting tight to None will preserve the previous setting.

Specifying any margin changes only the autoscaling; for example, if xmargin is not None, then xmargin times the X data interval will be added to each end of that interval before it is used in autoscaling.

New in version 1.1.0.

mouse_init(self, rotate_btn=1, zoom_btn=3)[source]

plot3D(self, xs, ys, *args, zdir='z', **kwargs)

Plot 2D or 3D data.

Parameters: xs1D array-likex coordinates of vertices. ys1D array-likey coordinates of vertices. zsfloat or 1D array-likez coordinates of vertices; either one for all points or one for each point. zdir{'x', 'y', 'z'}, default: 'z'When plotting 2D data, the direction to use as z ('x', 'y' or 'z'). **kwargsOther arguments are forwarded to matplotlib.axes.Axes.plot.
plot_surface(self, X, Y, Z, *args, norm=None, vmin=None, vmax=None, lightsource=None, **kwargs)[source]

Create a surface plot.

By default it will be colored in shades of a solid color, but it also supports colormapping by supplying the cmap argument.

Note

The rcount and ccount kwargs, which both default to 50, determine the maximum number of samples used in each direction. If the input data is larger, it will be downsampled (by slicing) to these numbers of points.

Note

To maximize rendering speed consider setting rstride and cstride to divisors of the number of rows minus 1 and columns minus 1 respectively. For example, given 51 rows rstride can be any of the divisors of 50.

Similarly, a setting of rstride and cstride equal to 1 (or rcount and ccount equal the number of rows and columns) can use the optimized path.

Parameters: X, Y, Z2D arraysData values. rcount, ccountintMaximum number of samples used in each direction. If the input data is larger, it will be downsampled (by slicing) to these numbers of points. Defaults to 50. New in version 2.0. rstride, cstrideintDownsampling stride in each direction. These arguments are mutually exclusive with rcount and ccount. If only one of rstride or cstride is set, the other defaults to 10. 'classic' mode uses a default of rstride = cstride = 10 instead of the new default of rcount = ccount = 50. colorcolor-likeColor of the surface patches. cmapColormapColormap of the surface patches. facecolorsarray-like of colors.Colors of each individual patch. normNormalizeNormalization for the colormap. vmin, vmaxfloatBounds for the normalization. shadebool, default: TrueWhether to shade the facecolors. Shading is always disabled when cmap is specified. lightsourceLightSourceThe lightsource to use when shade is True. **kwargsOther arguments are forwarded to Poly3DCollection.
plot_trisurf(self, *args, color=None, norm=None, vmin=None, vmax=None, lightsource=None, **kwargs)[source]

Plot a triangulated surface.

The (optional) triangulation can be specified in one of two ways; either:

plot_trisurf(triangulation, ...)


where triangulation is a Triangulation object, or:

plot_trisurf(X, Y, ...)
plot_trisurf(X, Y, triangles, ...)
plot_trisurf(X, Y, triangles=triangles, ...)


in which case a Triangulation object will be created. See Triangulation for a explanation of these possibilities.

The remaining arguments are:

plot_trisurf(..., Z)


where Z is the array of values to contour, one per point in the triangulation.

Parameters: X, Y, Zarray-likeData values as 1D arrays. colorColor of the surface patches. cmapA colormap for the surface patches. normNormalizeAn instance of Normalize to map values to colors. vmin, vmaxfloat, default: NoneMinimum and maximum value to map. shadebool, default: TrueWhether to shade the facecolors. Shading is always disabled when cmap is specified. lightsourceLightSourceThe lightsource to use when shade is True. **kwargsAll other arguments are passed on to Poly3DCollection

Examples

New in version 1.2.0.

plot_wireframe(self, X, Y, Z, *args, **kwargs)[source]

Plot a 3D wireframe.

Note

The rcount and ccount kwargs, which both default to 50, determine the maximum number of samples used in each direction. If the input data is larger, it will be downsampled (by slicing) to these numbers of points.

Parameters: X, Y, Z2D arraysData values. rcount, ccountintMaximum number of samples used in each direction. If the input data is larger, it will be downsampled (by slicing) to these numbers of points. Setting a count to zero causes the data to be not sampled in the corresponding direction, producing a 3D line plot rather than a wireframe plot. Defaults to 50. New in version 2.0. rstride, cstrideintDownsampling stride in each direction. These arguments are mutually exclusive with rcount and ccount. If only one of rstride or cstride is set, the other defaults to 1. Setting a stride to zero causes the data to be not sampled in the corresponding direction, producing a 3D line plot rather than a wireframe plot. 'classic' mode uses a default of rstride = cstride = 1 instead of the new default of rcount = ccount = 50. **kwargsOther arguments are forwarded to Line3DCollection.
quiver(X, Y, Z, U, V, W, /, length=1, arrow_length_ratio=0.3, pivot='tail', normalize=False, **kwargs)[source]

Plot a 3D field of arrows.

The arguments could be array-like or scalars, so long as they they can be broadcast together. The arguments can also be masked arrays. If an element in any of argument is masked, then that corresponding quiver element will not be plotted.

Parameters: X, Y, Zarray-likeThe x, y and z coordinates of the arrow locations (default is tail of arrow; see pivot kwarg). U, V, Warray-likeThe x, y and z components of the arrow vectors. lengthfloat, default: 1The length of each quiver. arrow_length_ratiofloat, default: 0.3The ratio of the arrow head with respect to the quiver. pivot{'tail', 'middle', 'tip'}, default: 'tail'The part of the arrow that is at the grid point; the arrow rotates about this point, hence the name pivot. normalizebool, default: FalseWhether all arrows are normalized to have the same length, or keep the lengths defined by u, v, and w. **kwargsAny additional keyword arguments are delegated to LineCollection
quiver3D(X, Y, Z, U, V, W, /, length=1, arrow_length_ratio=0.3, pivot='tail', normalize=False, **kwargs)

Plot a 3D field of arrows.

The arguments could be array-like or scalars, so long as they they can be broadcast together. The arguments can also be masked arrays. If an element in any of argument is masked, then that corresponding quiver element will not be plotted.

Parameters: X, Y, Zarray-likeThe x, y and z coordinates of the arrow locations (default is tail of arrow; see pivot kwarg). U, V, Warray-likeThe x, y and z components of the arrow vectors. lengthfloat, default: 1The length of each quiver. arrow_length_ratiofloat, default: 0.3The ratio of the arrow head with respect to the quiver. pivot{'tail', 'middle', 'tip'}, default: 'tail'The part of the arrow that is at the grid point; the arrow rotates about this point, hence the name pivot. normalizebool, default: FalseWhether all arrows are normalized to have the same length, or keep the lengths defined by u, v, and w. **kwargsAny additional keyword arguments are delegated to LineCollection

set_anchor(self, anchor, share=False)[source]

Define the anchor location.

The actual drawing area (active position) of the Axes may be smaller than the Bbox (original position) when a fixed aspect is required. The anchor defines where the drawing area will be located within the available space.

Parameters:
anchor2-tuple of floats or {'C', 'SW', 'S', 'SE', ...}

The anchor position may be either:

• a sequence (cx, cy). cx and cy may range from 0 to 1, where 0 is left or bottom and 1 is right or top.

• a string using cardinal directions as abbreviation:

• 'C' for centered
• 'S' (south) for bottom-center
• 'SW' (south west) for bottom-left
• etc.

Here is an overview of the possible positions:

 'NW' 'N' 'NE' 'W' 'C' 'E' 'SW' 'S' 'SE'
sharebool, default: False

If True, apply the settings to all shared Axes.

matplotlib.axes.Axes.set_aspect
for a description of aspect handling.
set_aspect(self, aspect, adjustable=None, anchor=None, share=False)[source]

Set the aspect ratios.

Axes 3D does not current support any aspect but 'auto' which fills the axes with the data limits.

To simulate having equal aspect in data space, set the ratio of your data limits to match the value of get_box_aspect. To control box aspect ratios use set_box_aspect.

Parameters:
aspect{'auto'}

Possible values:

value description
'auto' automatic; fill the position rectangle with data.

Currently ignored by Axes3D

If not None, this defines which parameter will be adjusted to meet the required aspect. See set_adjustable for further details.

anchorNone or str or 2-tuple of float, optional

If not None, this defines where the Axes will be drawn if there is extra space due to aspect constraints. The most common way to to specify the anchor are abbreviations of cardinal directions:

value description
'C' centered
'SW' lower left corner
'S' middle of bottom edge
'SE' lower right corner
etc.

See set_anchor for further details.

sharebool, default: False

If True, apply the settings to all shared Axes.

set_autoscale_on(self, b)[source]

New in version 1.1.0: This function was added, but not tested. Please report any bugs.

Parameters: bbool
set_autoscalez_on(self, b)[source]

Set whether autoscaling for the z-axis is applied on plot commands

New in version 1.1.0.

Parameters: bbool
set_axis_off(self)[source]

Turn the x- and y-axis off.

This affects the axis lines, ticks, ticklabels, grid and axis labels.

Turn the x- and y-axis on.

This affects the axis lines, ticks, ticklabels, grid and axis labels.

set_box_aspect(self, aspect, *, zoom=1)[source]

Set the axes box aspect.

The box aspect is the ratio of height to width in display units for each face of the box when viewed perpendicular to that face. This is not to be confused with the data aspect (which for Axes3D is always 'auto'). The default ratios are 4:4:3 (x:y:z).

To simulate having equal aspect in data space, set the box aspect to match your data range in each dimension.

zoom controls the overall size of the Axes3D in the figure.

Parameters: aspect3-tuple of floats or NoneChanges the physical dimensions of the Axes3D, such that the ratio of the axis lengths in display units is x:y:z. If None, defaults to 4:4:3 zoomfloatControl overall size of the Axes3D in the figure.

Set 3D x limits.

See matplotlib.axes.Axes.set_xlim() for full documentation.

set_xmargin(self, m)[source]

Set padding of X data limits prior to autoscaling.

m times the data interval will be added to each end of that interval before it is used in autoscaling. For example, if your data is in the range [0, 2], a factor of m = 0.1 will result in a range [-0.2, 2.2].

Negative values -0.5 < m < 0 will result in clipping of the data range. I.e. for a data range [0, 2], a factor of m = -0.1 will result in a range [0.2, 1.8].

Parameters: mfloat greater than -0.5
set_xscale(self, value, **kwargs)[source]

Set the x-axis scale.

Parameters: value{"linear"}The axis scale type to apply. 3D axes currently only support linear scales; other scales yield nonsensical results. **kwargsKeyword arguments are nominally forwarded to the scale class, but none of them is applicable for linear scales.
set_ylim(self, bottom=None, top=None, emit=True, auto=False, *, ymin=None, ymax=None)

Alias for set_ylim3d.

set_ylim3d(self, bottom=None, top=None, emit=True, auto=False, *, ymin=None, ymax=None)[source]

Set 3D y limits.

See matplotlib.axes.Axes.set_ylim() for full documentation.

set_ymargin(self, m)[source]

Set padding of Y data limits prior to autoscaling.

m times the data interval will be added to each end of that interval before it is used in autoscaling. For example, if your data is in the range [0, 2], a factor of m = 0.1 will result in a range [-0.2, 2.2].

Negative values -0.5 < m < 0 will result in clipping of the data range. I.e. for a data range [0, 2], a factor of m = -0.1 will result in a range [0.2, 1.8].

Parameters: mfloat greater than -0.5

Set the y-axis scale.

Parameters: value{"linear"}The axis scale type to apply. 3D axes currently only support linear scales; other scales yield nonsensical results. **kwargsKeyword arguments are nominally forwarded to the scale class, but none of them is applicable for linear scales.
set_zbound(self, lower=None, upper=None)[source]

Set the lower and upper numerical bounds of the z-axis.

This method will honor axes inversion regardless of parameter order. It will not change the autoscaling setting (get_autoscalez_on()).

New in version 1.1.0.

set_zlabel(self, zlabel, fontdict=None, labelpad=None, **kwargs)[source]

Set zlabel. See doc for set_ylabel for description.

Set the z-axis scale.

Parameters: value{"linear"}The axis scale type to apply. 3D axes currently only support linear scales; other scales yield nonsensical results. **kwargsKeyword arguments are nominally forwarded to the scale class, but none of them is applicable for linear scales.
set_zticklabels(self, labels, *, fontdict=None, minor=False, **kwargs)

Set the zaxis' labels with list of string labels.

Warning

This method should only be used after fixing the tick positions using Axes3D.set_zticks. Otherwise, the labels may end up in unexpected positions.

Parameters: labelslist of strThe label texts. fontdictdict, optionalA dictionary controlling the appearance of the ticklabels. The default fontdict is: {'fontsize': rcParams['axes.titlesize'], 'fontweight': rcParams['axes.titleweight'], 'verticalalignment': 'baseline', 'horizontalalignment': loc}  minorbool, default: FalseWhether to set the minor ticklabels rather than the major ones. list of TextThe labels. **kwargsText properties.
set_zticks(self, ticks, *, minor=False)

Set the zaxis' tick locations.

If necessary, the view limits of the Axis are expanded so that all given ticks are visible.

Parameters: tickslist of floatsList of tick locations. minorbool, default: FalseIf False, set the major ticks; if True, the minor ticks.

Notes

The mandatory expansion of the view limits is an intentional design choice to prevent the surprise of a non-visible tick. If you need other limits, you should set the limits explicitly after setting the ticks.

stem(self, x, y, z, *, linefmt='C0-', markerfmt='C0o', basefmt='C3-', bottom=0, label=None, orientation='z')[source]

Create a 3D stem plot.

A stem plot draws lines perpendicular to a baseline, and places markers at the heads. By default, the baseline is defined by x and y, and stems are drawn vertically from bottom to z.

Parameters:
x, y, zarray-like

The positions of the heads of the stems. The stems are drawn along the orientation-direction from the baseline at bottom (in the orientation-coordinate) to the heads. By default, the x and y positions are used for the baseline and z for the head position, but this can be changed by orientation.

linefmtstr, default: 'C0-'

A string defining the properties of the vertical lines. Usually, this will be a color or a color and a linestyle:

Character Line Style
'-' solid line
'--' dashed line
'-.' dash-dot line
':' dotted line

Note: While it is technically possible to specify valid formats other than color or color and linestyle (e.g. 'rx' or '-.'), this is beyond the intention of the method and will most likely not result in a reasonable plot.

markerfmtstr, default: 'C0o'

A string defining the properties of the markers at the stem heads.

basefmtstr, default: 'C3-'

A format string defining the properties of the baseline.

bottomfloat, default: 0

orientation{'x', 'y', 'z'}, default: 'z'

The direction along which stems are drawn.

Returns:
StemContainer

The container may be treated like a tuple (markerline, stemlines, baseline)

Examples

Individual keyword arguments can be used to override any given parameter:

>>> text(x, y, s, fontsize=12)


The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords ((0, 0) is lower-left and (1, 1) is upper-right). The example below places text in the center of the Axes:

>>> text(0.5, 0.5, 'matplotlib', horizontalalignment='center',
...      verticalalignment='center', transform=ax.transAxes)


You can put a rectangular box around the text instance (e.g., to set a background color) by using the keyword bbox. bbox is a dictionary of Rectangle properties. For example:

>>> text(x, y, s, bbox=dict(facecolor='red', alpha=0.5))

text3D(self, x, y, z, s, zdir=None, **kwargs)

Add text to the plot. kwargs will be passed on to Axes.text, except for the zdir keyword, which sets the direction to be used as the z direction.

tick_params(self, axis='both', **kwargs)[source]

Convenience method for changing the appearance of ticks and tick labels.

See matplotlib.axes.Axes.tick_params() for more complete documentation.

The only difference is that setting axis to 'both' will mean that the settings are applied to all three axes. Also, the axis parameter also accepts a value of 'z', which would mean to apply to only the z-axis.

Also, because of how Axes3D objects are drawn very differently from regular 2D axes, some of these settings may have ambiguous meaning. For simplicity, the 'z' axis will accept settings as if it was like the 'y' axis.

Note

Axes3D currently ignores some of these settings.

New in version 1.1.0.

tricontour(self, *args, extend3d=False, stride=5, zdir='z', offset=None, **kwargs)[source]

Create a 3D contour plot.

Changed in version 1.3.0: Added support for custom triangulations

Create a 3D filled contour plot.

Note

This method currently produces incorrect output due to a longstanding bug in 3D PolyCollection rendering.

Parameters: X, Y, Zarray-likeInput data. zdir{'x', 'y', 'z'}, default: 'z'The direction to use. offsetfloat, optionalIf specified, plot a projection of the contour lines at this position in a plane normal to zdir. *args, **kwargsOther arguments are forwarded to matplotlib.axes.Axes.tricontourf. matplotlib.tri.tricontour.TriContourSet

tunit_edges(self, vals=None, M=None)[source]
unit_cube(self, vals=None)[source]
update_datalim(self, xys, **kwargs)[source]

Extend the dataLim Bbox to include the given points.

If no data is set currently, the Bbox will ignore its limits and set the bound to be the bounds of the xydata (xys). Otherwise, it will compute the bounds of the union of its current data and the data in xys.

Parameters: xys2D array-likeThe points to include in the data limits Bbox. This can be either a list of (x, y) tuples or a Nx2 array. updatex, updateybool, default: TrueWhether to update the x/y limits.
view_init(self, elev=None, azim=None)[source]

Set the elevation and azimuth of the axes in degrees (not radians).

This can be used to rotate the axes programmatically.

'elev' stores the elevation angle in the z plane (in degrees). 'azim' stores the azimuth angle in the (x, y) plane (in degrees).

if 'elev' or 'azim' are None (default), then the initial value is used which was specified in the Axes3D constructor.

voxels([x, y, z, ]/, filled, facecolors=None, edgecolors=None, **kwargs)[source]

Plot a set of filled voxels

All voxels are plotted as 1x1x1 cubes on the axis, with filled[0, 0, 0] placed with its lower corner at the origin. Occluded faces are not plotted.

New in version 2.1.

Parameters: filled3D np.array of boolA 3D array of values, with truthy values indicating which voxels to fill x, y, z3D np.array, optionalThe coordinates of the corners of the voxels. This should broadcast to a shape one larger in every dimension than the shape of filled. These can be used to plot non-cubic voxels. If not specified, defaults to increasing integers along each axis, like those returned by indices(). As indicated by the / in the function signature, these arguments can only be passed positionally. facecolors, edgecolorsarray-like, optionalThe color to draw the faces and edges of the voxels. Can only be passed as keyword arguments. These parameters can be: A single color value, to color all voxels the same color. This can be either a string, or a 1D rgb/rgba array None, the default, to use a single color for the faces, and the style default for the edges. A 3D ndarray of color names, with each item the color for the corresponding voxel. The size must match the voxels. A 4D ndarray of rgb/rgba data, with the components along the last axis. shadebool, default: TrueWhether to shade the facecolors. Shading is always disabled when cmap is specified. New in version 3.1. lightsourceLightSourceThe lightsource to use when shade is True. New in version 3.1. **kwargsAdditional keyword arguments to pass onto Poly3DCollection. facesdictA dictionary indexed by coordinate, where faces[i, j, k] is a Poly3DCollection of the faces drawn for the voxel filled[i, j, k]. If no faces were drawn for a given voxel, either because it was not asked to be drawn, or it is fully occluded, then (i, j, k) not in faces.

Examples

property w_xaxis
property w_yaxis
property w_zaxis
zaxis_date(self, tz=None)

Set up axis ticks and labels to treat data along the zaxis as dates.

Parameters: tzstr or datetime.tzinfo, default: rcParams["timezone"] (default: 'UTC')The timezone used to create date labels.

Notes

This function is merely provided for completeness, but 3D axes do not support dates for ticks, and so this may not work as expected.

zaxis_inverted(self)[source]

Returns True if the z-axis is inverted.

New in version 1.1.0.
