title: 'numpy.float64' object has no attribute 'plot'
body: <p>I have a very simple code but at the end i found problem which I couldn't solve or find any solution.
  I can't draw plot. All I get is error AttributeError: 'numpy.float64' object has no attribute 'plot'</p>
  
  <pre><code>import pylab as p
  import numpy as np
  import sympy as s
  import matplotlib
  from random import random
  
  X=np.arange(0,1000)
  y=np.random.randint(100,size=1000)
  
  if len(X)==len(y):
      print "ok"
  else:
      print "not ok"
  
   polyfit=np.polyfit(X,y,6)
   poly1d=np.poly1d(polyfit)
   print poly1d
  
  
  i=1
  my=[]
  for i in X:
      p=poly1d(i)
      my.append(p)
  
   print my
  
   p.plot(X,my)
   p.show()
  </code></pre>
  
  <p>I look after docs but I found nothing,google also can't help me.</p>
