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.

Parameters:  value{"linear"}
The axis scale type to apply. 3D axes currently only support linear scales; other scales yield nonsensical results.
 **kwargs
Keyword arguments are nominally forwarded to the scale class, but none of them is applicable for linear scales.

set_zticklabels
(self, *args, **kwargs)[source]¶ Set zaxis tick labels. See
matplotlib.axes.Axes.set_yticklabels()
for more details.Note
Minor ticks are not supported by Axes3D objects.
New in version 1.1.0.

set_zticks
(self, *args, **kwargs)[source]¶ Set zaxis tick locations. See
matplotlib.axes.Axes.set_yticks()
for more details.Note
Minor ticks are not supported.
New in version 1.1.0.

text
(self, x, y, z, s, zdir=None, **kwargs)[source]¶ 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.

text2D
(self, x, y, s, fontdict=None, withdash=<deprecated parameter>, **kwargs)¶ Add text to the axes.
Add the text s to the axes at location x, y in data coordinates.
Parameters:  x, yscalars
The position to place the text. By default, this is in data coordinates. The coordinate system can be changed using the transform parameter.
 sstr
The text.
 fontdictdictionary, optional, default: None
A dictionary to override the default text properties. If fontdict is None, the defaults are determined by your rc parameters.
 withdashboolean, optional, default: False
Creates a
TextWithDash
instance instead of aText
instance.
Returns: Other Parameters:  **kwargs
Text
properties. Other miscellaneous text parameters.
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 lowerleft and (1, 1) is upperright). 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 zaxis.
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
Note
This method currently produces incorrect output due to a longstanding bug in 3D PolyCollection rendering.
Parameters:  X, Y, Zarraylikes
Input data.
 extend3dbool
Whether to extend contour in 3D; defaults to False.
 strideint
Step size for extending contour.
 zdir{'x', 'y', 'z'}
The direction to use; defaults to 'z'.
 offsetscalar
If specified, plot a projection of the contour lines at this position in a plane normal to zdir
 *args, **kwargs
Other arguments are forwarded to
matplotlib.axes.Axes.tricontour
.
Returns:  matplotlib.tri.tricontour.TriContourSet

tricontourf
(self, *args, zdir='z', offset=None, **kwargs)[source]¶ 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, Zarraylikes
Input data.
 zdir{'x', 'y', 'z'}
The direction to use; defaults to 'z'.
 offsetscalar
If specified, plot a projection of the contour lines at this position in a plane normal to zdir
 *args, **kwargs
Other arguments are forwarded to
matplotlib.axes.Axes.tricontourf
.
Returns:  matplotlib.tri.tricontour.TriContourSet
Notes
New in version 1.1.0: The zdir and offset parameters.
Changed in version 1.3.0: Added support for custom triangulations

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 arraylike
The points to include in the data limits Bbox. This can be either a list of (x, y) tuples or a Nx2 array.
 updatex, updateybool, optional, default True
Whether 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 bool
A 3d array of values, with truthy values indicating which voxels to fill
 x, y, z3D np.array, optional
The 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 noncubic 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, edgecolorsarraylike, optional
The color to draw the faces and edges of the voxels. Can only be passed as keyword arguments. This parameter 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
Whether to shade the facecolors. Defaults to True. Shading is always disabled when cmap is specified.
New in version 3.1.
 lightsource
LightSource
The lightsource to use when shade is True.
New in version 3.1.
 **kwargs
Additional keyword arguments to pass onto
Poly3DCollection()
Returns:  facesdict
A dictionary indexed by coordinate, where
faces[i, j, k]
is aPoly3DCollection
of the faces drawn for the voxelfilled[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
.

zaxis_date
(self, tz=None)[source]¶ Sets up zaxis ticks and labels that treat the z data as dates.
tz is a timezone string or
tzinfo
instance. Defaults to rc value.Note
This function is merely provided for completeness. Axes3D objects do not officially support dates for ticks, and so this may or may not work as expected.
New in version 1.1.0: This function was added, but not tested. Please report any bugs.
