Sure, just call "ax.xaxis_date()" (or "yaxis_date", depending on which axis
you want to represent a date).
As a quick example:
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import numpy as np
# Generate data...
ny = 100
xmin, xmax = mdates.datestr2num(['01/01/2011', '11/10/2011'])
data = np.random.random((ny, int(xmax-xmin)+1)) - 0.5
data = data.cumsum(axis=1)
# Plot...
fig, ax = plt.subplots()
ax.imshow(data, extent=[xmin, xmax, 0, ny])
ax.xaxis_date()
fig.autofmt_xdate()
plt.show()
