>>> import matplotlib.pylab as plt
>>> from scipy.stats import norm
>>> random_numbers = norm.rvs(0,1,size=10000)
>>> n, bins, pataches = plt.hist(random_numbers,normed=True,bins=25, alpha=0.75)>>> y = norm.pdf(bins)
>>> plt.plot(bins,y,"r-")
[<matplotlib.lines.Line2D object at 0x9cde1ac>]
>>> plt.xlabel("Random numbers")
<matplotlib.text.Text object at 0x9cdebcc>
>>> plt.ylabel("Density")
<matplotlib.text.Text object at 0x9ce488c>
>>> plt.title("My first matplotlib visualization!")
<matplotlib.text.Text object at 0x9ceb5cc>
>>> plt.savefig("matplotlib_first.png")
>>> 

and that dumps a matplotlib_first.png in your dir
