Possibility #1: Create a new figure before the second plot
>>>plot(x1,y1)
>>>figure()
>>>plot(x2,y2)

Possibility #2: Clear the figure before the second plot 
>>>plot(x1,y1)
>>>clf()
>>>plot(x2,y2)

Possibility #3: Force the current axes to refresh, by setting its "hold" 
property to "False"
>>>plot(x1,y1)
>>>gca().hold(False)
>>>plot(x2,y2)

Possibiltiy #4: Get familiar with the more pythonesque functions.
