Plotting Lines based on points



In [13]:

    
X = [1,2,3]
Y = [5,6,1]

plt.plot(X, Y)
plt.show()

Plotting Points



In [14]:

    
X = [1,2,3,4,9,3,7,1,2,8,5]
Y = [5,6,1,1,4,7,5,4,6,8,2]

plt.plot(X, Y,'*')
plt.show()

Plotting Math Functions



In [22]:

    
def f(x):
    return x**2

X = [i for i in range(-10,11)]
Y = [f(x) for x in X]

plt.plot(X,Y)
plt.show()

Plotting Random points



In [8]:

    
from random import randint

amount_points = 30

X = [i for i in range(amount_points)]
Y = [randint(0,9) for i in range(amount_points)]

plt.plot(X,Y,'.')
plt.show()
