Welcome to matplotlib.

import matplotlib
from matplotlib.matlab import *

pygtk.require() must be called before importing gtk
matplotlib requires pygtk-1.99.16 or greater -- trying anyway. Please
hold on

from matplotlib.backends.backend_gtk import ShowOn
ShowOn().set(1) # turning on interactive mode
dt=0.01
t=arange(dt,10.0,dt)
semilogy(t,t)
