I solved the problem and I'm going to explain the solution I used, it
can be useful for someone.
y data for each series are contained into 2 different arrays, say y1 and
y2.
The code is the sequent:
if max(y1) > max(y2):
y_max = max(y1)
else:
y_max = max(y2)
if min(y1) < min(y2):
y_min= min(y1)
else:
y_min = min(y2)
y_upper_limit = y_max+ y_max/10 # to leave some blank space on
the top
y_lower_limit = y_min + y_min/10 # to leave some blank space on
the bottom
Then, in your plot, you set ylim(y_lower_limit, y_upper_limit) and
that's it.
This solution is good because it doesn't depend on the order of
magnitude of the processed data, while specifying axes manually can give
some problems for very different data sets.
I hope this message is correctly sent to the mailing list, the procedure
for answering a message is not so immediate in my opinion.
Then, I subscribed the mailing list, so from the following messages (I
have some other problems) I will use a different e-mail address.
Bye :)

There has to be a better way to do this.

One way is to specify the axes manually, e.g. setting:
(with matyplotlib.pyplot importad as plt:)
plt.axis([200, 500, -600, 600])
...or whatever seems fitting for you, and do that on both of the y
axes.
That should align them nicely.
