In matplotlib
, how can I show a grid in 3D scatter plot?
In 2D plots I just do: plt.grid(True)
and it works like a charm. Now with 3D plots the same call returns a warning:
File "/usr/lib/pymodules/python2.7/matplotlib/pyplot.py", line 2792, in grid
ret = gca().grid(b, which, axis, **kwargs)
TypeError: grid() takes at most 2 arguments (4 given)
How do I do this?
回答1:
You can use the grid method of the axes to turn the grid on and off.
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
fig = plt.figure()
ax = fig.add_subplot(211, projection='3d')
ax.plot([1,2,3,4,5],[7,4,6,2,8],[4,6,8,9,2],'*')
ax.grid(True)
ax.set_title('grid on')
ax2 = fig.add_subplot(212, projection='3d')
ax2.plot([1,2,3,4,5],[7,4,6,2,8],[4,6,8,9,2],'*')
ax2.grid(False)
ax2.set_title('grid off')
plt.show()
