Bug report

I was attempting to make an interactive 3D line plot in jupyter notebook, but noticed that line3D set_data method only takes in x and y data.

Code for reproduction
The code below can be run outside of jupyter notebook to demonstrate the problem:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
x = [0, 1]
y = [0, 1]
z = [0, 1]
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
line = ax.plot(x,y,z)[0]
line.set_data([0,2], [0,2], [0,2])
plt.show()

Actual outcome

ValueError: too many values to unpack (expected 2)

Expected outcome

I would expect the set_data method exposed by line3D to take in 3 values.
