title: Why is the plot size barely changing when using matplotlib with Google Colab?
body: <p>I'm trying to plot a graph and individual dots together with Python within a Google Colab document, and I don't see much change in the size of the plot.</p>
  <p>It may be that I don't know how to declare a plot or figure, and when to call it, or that the fact that I'm overlapping plots interferes. There is a post with almost identical content, but doesn't solve my problem in <a href="https://stackoverflow.com/questions/52274643/figsize-in-matplotlib-is-not-changing-the-figure-size">here</a>.</p>
  <p>This is my code:</p>
  <pre><code>import numpy as np
  import matplotlib.pyplot as plt
  
  plt.figure(figsize=(800,100)) 
  
  s = np.random.normal(0,1,500)
  x = np.arange(0,len(s))
  
  f, ax = plt.subplots(1)
  
  plt.plot(x,s, color='k', LineWidth=.8)
  
  x_vals = np.linspace(0,500,20)
  y_vals = [0] * len(x_vals)
  
  plt.scatter(x_vals,y_vals, marker='.',color='red')
  </code></pre>
