Post Body

I'm having problems visualizing binomial distribution. What I'd like to have is discreet kind of histogram where each one is centered at values 0,1,2,....n and it's height corresponds to binomial pmf. Best I could do is:

%pylab inline --no-import-all
import numpy as np
from scipy.stats import binom
from pylab import *

n = 100
p = 0.5

x = np.array(list(range(0, n   1)))
x
y = binom.pmf(x, n, p)
y

plot(x,y)

which gives me continuous line. Thank you for helping a newbie out.
