How to hide axes and gridlines in Matplotlib (python)

Turn the axes off with:

plt.axis('off')

And gridlines with:

plt.grid(b=None)

# Hide grid lines
ax.grid(False)

# Hide axes ticks
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])

Note, you need matplotlib>=1.2 for set_zticks() to work.
