Plotting a gaussian (tutorial)

Example matplotlib to plot a gaussian.

Let’s import numpy and matplotlib

 import numpy as np
 import matplotlib.pyplot as plt

Methods

First, lets define the gaussian method

 def gaussian(x, mu=0, sig=1):
     return np.exp(-np.power(x - mu, 2.) / (2 * np.power(sig, 2.)))

Main

Lets create the x and y values

 x = np.linspace(-3, 3, 120)
 y = gaussian(x)

Lets plot using matplotlib

 plt.plot(x, y)
 plt.show()
