I am trying to plot the following !

from numpy import *
from pylab import *
import random

for x in range(1,500):
    y = random.randint(1,25000)
    print(x,y)   
    plot(x,y)

show()

However, I keep getting a blank graph (?). Just to make sure that the program logic is correct I added the code print(x,y), just the confirm that (x,y) pairs are being generated.

(x,y) pairs are being generated, but there is no plot, I keep getting a blank graph.

Any help ?
