Re: [Matplotlib-users] installating matplotlib in mac 10.7.4 for python 2.6

[lulu <lau...@me...>]

oh brother -- so now I've got to deal w/ Apple...
okay thanks.

here's where I am.

I've downloaded matplotlib, numpy, python 2.7.3, xcode and macports to
simply plot this oh-so-simple code!
Which is:

Curve fitting with python and pylab
#import the lib
from pylab import *
# assuming this data set
t = (0,5,10,15,20,25,30,35,40,50)
V = (1,7,14,15,16,22,25,27,28,30)
#show the data
plot(t, v, linewidth=2.0)
#assume an order
N = ?
#find the coefficient of the polynomial
coeffs = polyfit(t,v,N)
#get the polynomial output for the input
best = polyval(coeffs, t)
#print the coefficients
print(coeffs)

I have written it like this in python 2.6:

import os,sys
import numpy 
#import pylab

t = (0,5,10,15,20,25,30,35,40,50)
V = (1,7,14,15,16,22,25,27,28,30)
#scipy.plot(t,v,linewidth=2.0)

n = 4
coeffs = numpy.polyfit(t,V,n)

best = numpy.polyval(coeffs,t)

print coeffs
print best

and when I run the program, I get this:
[ -1.68165168e-05   1.71262071e-03  -6.39152514e-02   1.59163337e+00
   1.04578755e+00]
[  1.04578755   7.60964036  12.11505162  15.46811522  18.32267732
  21.08033633  23.89044289  26.6500999   29.0041625   29.81368631]

when I run in 2.7.3 it looks like this:
import os,sys
import numpy as np
import pylab

t = (0,5,10,15,20,25,30,35,40,50)
V = (1,7,14,15,16,22,25,27,28,30)
#scipy.plot(t,v,linewidth=2.0)

n = 4
coeffs = numpy.polyfit(t,V,n)

best = numpy.polyval(coeffs,t)

print coeffs
print best


And my error msg is this:
ImportError: No module named numpy

any ideas?
What I'm looking for is a visual.
