You could always just save it as a list and then plot from there?
The average calculation is a bit redundant though, I'm sure theres a better
way of doing it
import pylab
import numpy
>>f = open( 'myfile.txt','r')
mass_store =[]
>>for line in f:
>>if line != ' ':
>> line = line.strip() # Strips end of line character
>> columns = line.split() # Splits into coloumn
>> mass = columns[8] # Column which contains mass values
>> print(mass)
mass_store.append(mass)
>>
pylab.plot(range(len(mass_store)),mass_store)
pylab.plot(range(len(mass_store)),[numpy.mean(mass_store)]*len(mass_store))
pylab.show() (or pylab.savefig('location.png') to save )
