You can use numpy's loadtxt() to load columns of data into memory and use the plot function to plot them. http://docs.scipy.org/doc/numpy/reference/generated/numpy.loadtxt.html
so in yt it would look something like
from yt.mods import * ...some yt stuff that saves to myfile.txt...
import numpy as na col1, col2 = na.loadtxt("myfile.txt", usecols=(0,1)) pylab.plot(col1,col2)
This is assuming your ASCII data is in columns. Essentially starting from import numpy, this is just a matplotlib script which can be separate from the yt stuff above.

How we can use yt to plot ASCII files like gnuplot. Any simple example will be really appreciated.
