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 :meth:`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. .. versionadded :: 1.1.0 This function was added, but not tested.

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:: While this function is currently implemented, the core part of the Axes3D object may ignore some of these settings.

This method creates three dimensional barplot where the width, depth, height, and color of the bars can all be uniquely set. Parameters ---------- x, y, z : array-like The coordinates of the anchor point of the bars. dx, dy, dz : scalar or array-like The width, depth, and height of the bars, respectively. color : sequence of valid color specifications, optional The color of the bars can be specified globally or individually. This parameter can be: - A single color value, to color all bars the same color. - An array of colors of length N bars, to color each bar independently. - An array of colors of length 6, to color the faces of the bars similarly. - An array of colors of length 6 * N bars, to color each face independently.

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. Keyword arguments: *length*: [1.0 | float] The length of each quiver, default to 1.0, the unit is the same with the axes *arrow_length_ratio*: [0.3 | float] The ratio of the arrow head with respect to the quiver, default to 0.3 *pivot*: [ 'tail' | 'middle' | 'tip' ] The part of the arrow that is at the grid point; the arrow rotates about this point, hence the name *pivot*. Default is 'tail' *normalize*: bool When True, all of the arrows will be the same length. This defaults to False, where the arrows will be different lengths depending on the values of u,v,w.

Call signatures:: voxels(filled, facecolors=fc, edgecolors=ec, **kwargs) voxels(x, y, z, filled, facecolors=fc, edgecolors=ec, **kwargs) .. versionadded:: 2.1 Parameters ---------- filled : 3D np.array of bool A 3d array of values, with truthy values indicating which voxels to fill x, y, z : 3D 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 non-cubic voxels. If not specified, defaults to increasing integers along each axis, like those returned by :func:`~numpy.indices`. As indicated by the ``/`` in the function signature, these arguments can only be passed positionally. facecolors, edgecolors : array_like, 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. **kwargs Additional keyword arguments to pass onto :func:`~mpl_toolkits.mplot3d.art3d.Poly3DCollection` Returns ------- faces : dict A 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``.
