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
The code is the sequent:
if max(y1) > max(y2):
y_max = max(y1)
y_max = max(y2)
if min(y1) < min(y2):
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
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.

One way is to specify the axes manually,
(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.
