Hi Ryugan,

There are a lot of ways to do this, I dont know them all. Here are a few 
to get you started:

from matplotlib.matlab import *

a=arange(10)
b=a*2
c=a*3
figure(1)
plot(a,b,a,c)
figure(2)
plot(a,b,'k',a,c,'r')

figure(3)
[plot(a,i) for i in [b,c]]
#equivalent to:
figure(4)
for i in [b,c]:
    plot(a,i)
