In python, the library matplotlib.pyplot is a collection of command style functions that make
matplotlib work like MATLAB. Each pyplot function makes some change to a figure: e.g.,
creates a figure, creates a plotting area in a figure, plots some lines in a plotting area, decorates
the plot with labels, etc. In matplotlib.pyplot various states are preserved across function calls, so
that it keeps track of things like the current figure and plotting area, and the plotting functions are
directed to the current axes (please note that "axes" here and in most places in the documentation
refers to the axespart of a figure and not the strict mathematical term for more than one axis).
Sample Codes:
import numpy as np
import matplotlib.pvplot as plt
ax = plt.subplot(111)
t = np.arange(0.0, 5.0, 0.01)
S = np.cos(2*np.pi*t)
line, = plt.elot(t, s, lw=2)
plt.annotate('local max', xy=(2, 1), xytext=(3, 1.5),
arrowprops=dict(facecolor='black', shrink=0.05),
plt.vlim(-2,2)
plt.show()
