Give this a shot:
# 
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(20)
y = np.random.randn(20)
y = y/y.max() * 100
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x,y,'ko', mfc='none')
# you can do this:
ax.set_ylim([0,100])
# or something like this:
ax.set_ylim(ymin=0, ymax=100)
plt.show()
