invisible plot

I'm a newbie to matplotlib. When I try to generate a simple plot, nothing
happens. Any advice will be appreciated. Here's my code:

from numpy import *
from matplotlib import *

x= arange(0,10.,0.1)
y= x**1.5 - 0.25*x**2

pyplot.figure(figsize=(9, 6), dpi=120)
pyplot.plot(x, y)

Add this to the end of the script (after all the plotting):

pyplot.show()

Or run inside "ipython -pylab".

Hmm, I don't think you copied that quite right.
Anyway::

    import numpy as np
    from matplotlib import pyplot as plt

    x= np.arange(0,10.,0.1)
    y= x**1.5 - 0.25*x**2

    fig = plt.figure(figsize=(9, 6), dpi=120)
    myplot = plt.plot(x, y)

    plt.show()

Hi Phillip,

Don't you need to call

pyplot.show()

at the end of the script?
