try something like that :

import Numeric,pylab,string

def plotfromfile(file="data",using=(3,4),skippingline=1):
	f=open(file,'r')
	for i in range(skippingline):
		f.readlines()
	res=Numeric.array([[string.atof(x)] for x in 
string.split(y)[using[0]:using[-1]+1] for y in f.readlines()])
	
	for u in using :
		pylab.plot(res[:,u])
	pylab.show()
