[Matplotlib-users] Grid problem?

[David P. <dpe...@wi...>]

When I try to turn on the grid for just one axis, seemingly in perfect accordance with the documentation at 
http://matplotlib.sourceforge.net/api/axes_api.html#matplotlib.axes.Axes.grid

it seems like there is a problem.  I am able to make a graph, but trying to turn on the grid for just one axis causes an error.

My commands are pasted below.

Am I doing this wrong?  I am doing the best I can to follow the documentation exactly.

Thanks for any help!


import matplotlib
matplotlib.use('MacOSX')
import matplotlib.pyplot as plt
fig=plt.figure()
ax=fig.add_subplot(111)
ax.plot([1,2,3])
ax.set_xlabel('Hi there')
ax.grid(True, axis='x')
