The following minimal code example illustrates a problem I'm having.
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
# succeeds
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
plt.show()
# succeeds
fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_xscale("log")
plt.show()
# fails
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.set_xscale("log")
plt.show()
Here is the traceback:

I am hoping to use logarithmic axes in a 3D plot. I haven't found
anything in the documentation which says that I am restricted to linear
scaling. My system configuration is: Python 3.4, Matplotlib 1.3.1,
Ubuntu Linux 14.04 64-bit. My system is selecting the TKAgg backend.
Any advice is appreciated, thanks!
