See this cookbook entry: <http://www.scipy.org/Cookbook/Matplotlib/Arrows>
What I usually do in these circumstances (and what is demonstrated in the
cookbook entry) is to plot the points, and then add an arrow patch for each
pair:
arrow = pylab.Arrow ( x_from, y_from, distance_x, distance_y )
ax = pylab.gca()
ax.add_patch(arrow)
Hope that helps!
Jose
