If you tried to plot a bunch of values divided by 1000, they may well all be integer 0, and so you wouldn't see any line (it would be at the x-axis). You would need to force python to do floating point division: 1/1000.0 = 0.001; to do this you need to make sure one of the numbers in the division is floating point: the simplest way to do this is 1/1000.0 (or 1/1000. for short).

Replace this line: ax.plot(f/1000, Sserie) With this line: ax.plot(f/1000.0, Sserie) And tell us how things go. Python 2.6 distinguishes between integers and floats very strictly. Hence: In [1]: 20/1000 Out[1]: 0 In [2]: 20.0/1000.0 Out[2]: 0.02 See the difference? -paul From: Waléria Antunes David [mailto:wal...@gm...] Sent: Monday, July 26, 2010 10:01 AM To: Angus McMorland Cc: mat...@li...
