Start from zero and do a random walk.
import matplotlib.pyplot as plt
x = [0]
y = [0]
c = [0]
import random
for ii in range(0, 500):
x.append(x[-1] + random.uniform(-2, 2))
y.append(y[-1] + random.uniform(-2, 2))
c.append(x[-1] + y[-1])
plt.plot(x, color='r')
plt.plot(y, color='g')
plt.plot(c, color='b')
plt.show()
Just a cool visualization of a bunch of random walks starting from zero.
a = []
N = 100
for i in range(0, N):
a.append([0])
import random
for ii in range(0, 500):
for j in range(0, N):
a[j].append(a[j][-1] + random.uniform(-2, 2))
for j in range(0, N):
plt.plot(a[j], color='g')
plt.show()
