AXES Demo

#!/usr/bin/env python

from pylab import *

# create some data to use for the plot

dt = 0.001
t  = arange(0.0, 10.0, dt)
r  = exp(-t[:1000]/0.05)        # impulse response
x  = randn(len(t))
s  = convolve(x,r)[:len(x)]*dt  # colored noise

# the main axes is subplot(111) by default

plot(t, s)

ylabel('current (nA)')
title('Gaussian colored noise')

# this is an inset axes over the main axes
