Description
the following does not work:
import matplotlib.pyplot as plt
ls = (0,(2,2))
plt.plot()
line = plt.axvline(1,linestyle=ls)
however:
line.set_linestyle(ls)
produces the expected result. both axhline and axvline are affected, axhspan and axvspan not.
matplotlib '1.5.1' installed through Anaconda on Ubuntu 15.10.
Traceback:
