How to plot graph?

[maximus tee]

hi all,

i'm new to python and this is advanced for me. is there a way to plot data with python? i want to plot EyVt, EyHt on the Y-axis and Lane on the X-axis as attached or below.
currently i'm using Python2.5 and Win XP. thanks a lot.
Eg:
Platform: PC
Tempt : 25
TAP0 :0
TAP1 :1
+++++++++++++++ +++++++++++++++ +++++++++++++++
Port Chnl Lane EyVt EyHt
+++++++++++++++ +++++++++++++++ +++++++++++++++
0 1 1 75 55
0 1 2 10 35
0 1 3 25 35
0 1 4 35 25
0 1 5 10 20
+++++++++++++++ +++++++++++++++ +++++++++++++++

The Python wiki is always a good place to start http://wiki.python.org/moin/NumericA...%7C%28graph%29.

thanks. i installed matplotlib, numpy, scipy and when running this code there was error:

import numpy as np 
from numpy import cos 
from scipy import * 
from pylab import plot, show, ylim, yticks 
from matplotlib import * 
from pprint import pprint 
 
n1 = 1.0 
n2 = 1.5 
 
#alpha, beta, intensity 
data = np.array([ 
    [10,    22,     4.3], 
    [20,    42,     4.2], 
    [30,    62,     3.6], 
    [40,    83,     1.3], 
    [45,    102,    2.8], 
    [50,    123,    3.0], 
    [60,    143,    3.2], 
    [70,    163,    3.8], 
    ]) 
 
# Populate arrays 
x = np.array([row[0] for row in data]) 
y1 = np.array([row[1] for row in data]) 
rhotang1 = n1*cos(data[:,0]) - n2*cos(data[:,1]) 
rhotang2 = n1*cos(data[:,0]) + n2*cos(data[:,1]) 
y3 = rhotang1 / rhotang2 
 
plot(x, y1, 'r--', x, y3, 'g--') 
show()
