displaying multiple grayscale figures in python's matplotlib

from matplotlib import pyplot as plt
import matplotlib.cm as cm
plt.figure()  # without this it display one after another
plt.imshow(image_one, cmap=cm.gray) # without cm.gray it displays grayscale images in colormap
plt.imshow(image_two, cmap=cm.gray) #
plt.show()

use
%matplotlib inline
in ipython notebook to display image inplace


Shorter version:
%matplotlib inline
import matplotlib.pyplot as plt
plt.axis('off')
plt.imshow(dpt, cmap=plt.cm.gray, interpolation='nearest')
