Matplotlib wraps the graph

I've never seen this before. Can you provide a free-standing,
complete example?

Could this be a data type issue?

from numpy import arange
arange(120, 130, dtype=Int8)

Out: array([ 120, 121, 122, 123, 124, 125, 126, 127, -128, -127],
dtype=int8)

I will have to check this, but I do not think that is the problem. The
data is used in another algorithm which locates the correlation
maximum between two sliding windows (to detect the start of a data
msg), and the algorithm returns the correct result, only the plot is
wrong.

I tried this again on Fedora Core 6, and the problem seems to be solved.
