I'm not sure that you mean by scale but in any case, list_plot, and its
options, is described here
http://www.sagemath.org/doc/html/ref/m
thx for theses examples, but now i don't found how to scale my plot, i
used list_plot

This should work for you
sage: import numpy
sage: a=numpy.loadtxt('my_file.txt')
sage: x_vals=a[:,1]
sage: y_vals=a[:,2]
note that now x_vals and y_vals are numpy arrays. At this point you
have a few ways of
of doing the ftt
Option 1
sage: from numpy import fft
sage: fft.fft(x_xvals)
sage: fft.
simple txt file with columns
first column is the time, second the X velocity value, third the Y
velocity value
and I want to fft each components of velocity to get the frequency of
oscillations.
(sry for my bad english)

thx, I will try the fft() method, other question, how can I load my
datas in a vector ?

No, the Sage programming language is Python, which is as
different from Matlab's language as Mat
