[cut out code snippet]
You can always use subplots_adjust. I haven't looked into the details of your
code, but it appears as though the actual plot (the actual graphics) is well
within the margins of your subplot (extending the boundaries of the subplot
would still leave a lot of white space). To counteract this you can use
negative padding (and padding greater than 1); e.g.
subplots_adjust(top=1, bottom=-0.2, left=-0.3, right=1.3)
(you can add this right before "savefig".) This means that the actual
boundaries of the subplot extend outside the figure (which normally have
extents from 0 to 1). The above gives pretty good results. To get any better, I
think you need to adjust the aspect ratio of the figure to match the plot (you
can do this by creating a "figure" and passing a value for "figsize").

P.S. since you posted code, I'll offer an unsolicited suggestion. :) You can
replace all your annotate commands (except for the last 2) with two short loops:
for y in np.arange(-1.4, 1.5, 0.2):
annotate("", xy=(-pi/2., y), xytext=(-ini, y), arrowprops=dict(fc="g"))
for y in np.arange(-1.4, 1.5, 0.2):
annotate("", xy=(pi/2., y), xytext=(ini, y), arrowprops=dict(fc="g"))
