3D axes object.
Parameters: 


Notes
New in version 1.2.1: The sharez parameter.
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.
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.

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.

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.
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: This function was added, but not tested. Please report any bugs.
mouse_init
(self, rotate_btn=1, zoom_btn=3)[source]¶Initializes mouse button callbacks to enable 3D rotation of the axes. Also optionally sets the mouse buttons for 3D rotation and zooming.

By default it will be colored in shades of a solid color, but it also supports color mapping 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.
Parameters: 


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:

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.

plot_wireframe
(self, X, Y, Z, *args, **kwargs)[source]¶Plot a 3D wireframe.

By default, Matplotlib supports the above mentioned scales.
Additionally, custom scales may be registered using
matplotlib.scale.register_scale
. These scales may then also
be used here as support is added.
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.

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: 


Returns:  
Other 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
While this function is currently implemented, the core part of the Axes3D object may ignore some of these settings. Future releases will fix this. Priority will be given to those who file bugs.
New in version 1.1.0: This function was added, but not tested. Please report any bugs.
ticklabel_format
(self, *, style='', scilimits=None, useOffset=None, axis='both')[source]¶Convenience method for manipulating the ScalarFormatter used by default for linear axes in Axed3D objects.
See matplotlib.axes.Axes.ticklabel_format()
for full
documentation. Note that this version applies to all three
axes of the Axes3D object. Therefore, the axis argument
will also accept a value of 'z' and the value of 'both' will
apply to all three axes.
New in version 1.1.0: This function was added, but not tested. Please report any bugs.
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: 


Returns: 

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: 


Returns: 

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: 


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.

Returns:

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.
