matplotlib for graph script for python

[baber]

Question1:

#col1    col2     col3            col4
171.4    130.5    7.2245646       0.3933173
98.2    133.1    6.8370089      -0.4387156
4.8    12.8    2.9705532      -1.4150375
225.1    193.5    7.705306      0.2182325
 

Columns are separated with "\t".

I would like to plot of col3, col4 (from text data file) in order to
get a plot like:

  y
  1 |
    |          *    *
    |      * *  *    *   *
    0 _ _ *_ _ *__ *_ *_ _ _ _ _
    |    * *  * * *   *  *
    |     *  *   * *     *    *
  -1| ______________________ x
 

How to do it using matplotlib?

Question 2:
I try to make a plot using my column data like lists. Like:

########

from pylab import *
x = [1.3, 4.5, 5]
y = [2.3, 4.1, 6]
plot(x,y)
xlabel('xaxe')
ylabel('yaxe')
title('Plot name')
plot(x,y,'r',label="Gallup",color='r',linewidth=0,markerfacecolor='g', markeredgecolor='y',marker='d')
legend()
show()

#######
Result: I got back a line plot. I known that is a bad way.
What is the best way for list?
Thanks
