Pyplot

In the Matplotlib object-oriented drawing library, Pyplot is a convenient interface.

Basic drawing functions

Mp.plot (array of horizontal coordinates, array of vertical coordinates)

 1  from  __future__  import   unicode_literals  2  import   NumPy as NP  3  import   Matplotlib.pyplot as MP  4  x = Np.linspace (-np.pi, Np.pi, 1000)  5  cos_y = Np.cos (x)/26  sin_y = Np.sin (x)  7  mp.plot (x, cos_y)  8  mp.plot (x, sin_y)  9  mp.show () 

Simple Chestnuts

np.linspace(...)The mean is to take 1000 points evenly from-π to + π .
