Some example code for how to plot an arrow using the Arrow function.

   1 from pylab import *
   2 from numarray import *
   3 
   4 x = arange(10)
   5 y = x
   6 
   7 # Plot junk and then a filled region
   8 plot(x, y)
   9 
  10 # Now lets make an arrow object
  11 arr = Arrow(2, 2, 1, 1, edgecolor='white')
  12 
  13 # Get the subplot that we are currently working on
  14 ax = gca()
  15 
  16 # Now add the arrow
  17 ax.add_patch(arr)
  18 
  19 # We should be able to make modifications to the arrow.
  20 # Lets make it green.
  21 arr.set_facecolor('g')
