Hi,

I want to plot data from two different datafiles. To do so I use
numpy.loadtxt two times in the script (see below).
The problem is, that I don't get any output: no resulting plot, no
errormessages or something in the terminal.
Even if I comment-out one loadtxt-row nothing happens. Even if I try
to plot something simple without using the loaded datafiles, nothing
happens. Other files with simple plots without using a datafile work
fine.
Can't find my mistake.

Manuel

#!/usr/bin/env python
from pylab import *
import numpy as np

datafile1 = '/path/to/datafile1.dat'
datafile2 = '/path/to/datafile2.dat'

TIME_F, STIRRER, O2, CO2 = np.loadtxt(datafile1, dtype='float',
comments='#', delimiter='\t', usecols=(0,1,2,3), unpack=True)
TIME_H, OD, FLUOR, BTM, GLY = np.loadtxt(datafile2, dtype='float',
comments='#', delimiter='\t', usecols=(0,1,2,3,4), unpack=True)

plot(TIME_F, O2)
