Chapter 4, example 1

Here, we show basic plotting examples with Matplotlib.

We first plot a white noise signal, consisting of independent normal random values.



In [1]:

    
y = randn(1000)



In [2]:

    
plot(y)









    Out[2]:





[<matplotlib.lines.Line2D at 0x4cf4cf0>]

We can also specify the x values, which just changes the x axis here.



In [3]:

    
x = linspace(0., 1., 1000)



In [4]:

    
plot(x, y)









    Out[4]:
