Have you shown us your entire index() function? If so, your view file isn't
getting called at all because your index function is not returning a
dictionary. Instead, web2py is simply returning whatever your function
returns, which is probably None if the last line is a call to plt.savefig().
Add return dict() to the end of your index function, and see if it works.
Views are only called if the controller function returns a dictionary.
