Thanks for your help; the question is a bit unclear indeed...
Handling the sys.argv was not the problem; actually my main
problem is to tell the
'plot' or 'loglog' command, that I have a different number
of arrays.
Lets say I have to columns, the I could use in a script:
	 res=plot(array_mapped[:,0],array_mapped[:,1], 'b',
 array_mapped[:,0],array_mapped[:,2], 'g')
The next time a have 5 columns in a file and want to plot
all 5 columns without adjusting the 'plot' command
in the script, but just by defining an argument when
starting the script. I have to adjust somehow dynamically
the plot command to adjust the number of graphs in one
figure; but that is the problem...

import numpy
import pylab
x = y = ybar = numpy.arange(0, 10)
errorbar(x, y, ybar)
errorbar(x, 2 * y, 0.5 * ybar)
legend(["hi" , "hi2"], loc=0)
That gave a AttributeError: LineCollection instance has no attribute
'get_lines'.
I'm running matplotlib on Debian Lenny. Thanks a lot.
