class matplotlib.projections.polar.PolarAffine (scale_transform, limits) [source] ¶ Bases: matplotlib.transforms.Affine2DBase. Matplotlib was initially designed with only two-dimensional plotting in mind. Questions: I have the following 2D distribution of points. contour (X, Y, Z, 16, extend3d = True) ax. pyplot as plt fig = plt. fig=plt.figure() Now, to create a blank 3D axes, you just need to add “projection=’3d’ ” to plt.axes() axes = plt.axes(projection='3d') The output will look something like this: Now we add label names to each axis. Create a new matplotlib.figure.Figure and add a new axes to it of type Axes3D: import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D fig = plt.figure() ax = fig.add_subplot(111, projection='3d') Can't you just call plot3D or plot_surface or similar directly without calling subplot with the projection="3d" argument? However I run into the error detailed below. I just installed matplotlib and am trying to run one of there example scripts. The affine part of the polar projection. axes3d # register 3d projection: class GeneticController (object): def __init__ (self): My goal is to perform a 2D histogram on it. gca (projection = '3d') X, Y, Z = axes3d. matplotlib Brought to you by: cjgohlke, dsdale, efiring, heeres, and 8 others. matplotlib.pyplot中add_subplot(111, projection='3d')报错ValueError: Unknown projection '3d'时，检查matplotlib版本在1.0.x以上时导入from mpl_toolkits.mplot3d import Axes3Df就解决问题了 (Try running: python -c 'import matplotlib; print matplotlib. An Axes3D object is created just like any other axes using the projection=‘3d’ keyword. figure ax = fig. If you're running version 0.99, try doing this instead of using using the projection keyword argument: return (vmax-vmin) * np. Insert the command below in top of your script. random.

Why. ticker import LinearLocator, FixedLocator, FormatStrFormatter: import numpy as np: import mpl_toolkits. Just to add to Joe Kington’s answer (not enough reputation for a comment) there is a good example of mixing 2d and 3d plots in the documentation at http://matplotlib.org/examples/mplot3d/mixed_subplots_demo.html which shows projection=’3d’ working in combination with the Axes3D import. (Try running: python -c 'import matplotlib; print matplotlib. Also, if you run "ipython -pylab", what is the value of pylab.__file__ and how does it compare to matplotlib.__file__ and mpl_toolkits.mplot3d.__file__?
