The behavior you are seeing is called "tick offset" and is controlled by the
axis tick formatter. This can be controlled in different ways, but here is
one approach:
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(1000, 1010)
y = np.random.random((10,))
fig = plt.figure()
ax = fig.gca()
ax.plot(x, y)
# Get the formatter for the major ticks of the x-axis
# and set the 'useOffset' attribute to False.
ax.get_xaxis().get_major_formatter().set_useOffset(False)
plt.show()
I hope that helps!
