mplot3d API

axes3d

Note

Significant effort went into bringing axes3d to feature-parity with regular axes objects for version 1.1.0. However, more work remains. Please report any functions that do not behave as expected as a bug. In addition, help and patches would be greatly appreciated!

axes3d.Axes3D(fig[, rect]) 3D axes object.

axis3d

Note

See mpl_toolkits.mplot3d.axis3d._axinfo for a dictionary containing constants that may be modified for controlling the look and feel of mplot3d axes (e.g., label spacing, font colors and panel colors). Historically, axis3d has suffered from having hard-coded constants that precluded user adjustments, and this dictionary was implemented in version 1.1 as a stop-gap measure.

axis3d.Axis(adir, v_intervalx, d_intervalx, …)

art3d

art3d.Line3D(xs, ys, zs, *args, **kwargs) 3D line object.
art3d.Line3DCollection(segments, *args, **kwargs) A collection of 3D lines.
art3d.Patch3D(*args, **kwargs) 3D patch object.
art3d.Patch3DCollection(*args, **kwargs) A collection of 3D patches.
art3d.Path3DCollection(*args, **kwargs) A collection of 3D paths.
art3d.PathPatch3D(path, **kwargs) 3D PathPatch object.
art3d.Poly3DCollection(verts, *args, **kwargs) A collection of 3D polygons.
art3d.Text3D([x, y, z, text, zdir]) Text object with 3D position and (in the future) direction.

Art3D Utility Functions

art3d.get_colors(c, num) Stretch the color argument to provide the required number num
art3d.get_dir_vector(zdir)
art3d.get_patch_verts(patch) Return a list of vertices for the path of a patch.
art3d.iscolor(c)

Deprecated since version 2.0.

art3d.juggle_axes(xs, ys, zs, zdir) Reorder coordinates so that 2D xs, ys can be plotted in the plane orthogonal to zdir.
