Hide histogram plot

So I want to plot a normal distribution, and I've seen one way to do this is by using this code:

import numpy as np
import matplotlib.pyplot as plt

mu = 5
sigma = 1

s = np.random.normal(mu, sigma, 1000)

count, bins, ignored = plt.hist(s, 100, normed=True);
pdf = 1/(sigma * np.sqrt(2 * np.pi)) * np.exp(- (bins - mu)**2 / (2 * sigma**2))

mu_ = 10
sigma_ = 1
s = np.random.normal(mu_, sigma_, 1000)

count_, bins_, ignored_ = plt.hist(s, 100, normed=True);
pdf_ = 1/(sigma_ * np.sqrt(2 * np.pi)) * np.exp(- (bins_ - mu_)**2 / (2 * sigma_**2))

plt.plot(bins, pdf, linewidth=2, color='g')
plt.plot(bins_, pdf_, linewidth=2, color='r')

plt.show()


And the result is:

enter image description here

My question is, can I somehow hide the histogram plot so only the normal distribution line is shown?? I know there is another way to plot normal distribution, but I kinda prefer this way

Thank you for the help!!!

Answer

Try adding plt.clf() right before:

plt.plot(bins, pdf, linewidth=2, color='g')
plt.plot(bins_, pdf_, linewidth=2, color='r')

This will clear the histogram, while still allowing you to use the output from it being drawn. If you'd like to have two separate figures, one with histogram and one with lines, add plt.figure() instead of plt.clf().
