title: How to scale down the y-axis in matplotlib/python?
body: <p>This is more of a math question than a matplotlib question but if there is a way to do this specifically in matplotlib that would be great. </p>
  
  <p>I have a set of points with the max-y-value and the min-y-value can have a difference anywhere from a few hundred to a few thousand. </p>
  
  <p>I am trying to plot these points in a very small scale on the y-axis (maybe a span of 2 units). </p>
  
  <p>For example, I have the points (10, 20) (11, 123) (12, 77) (13, 124) and I want to plot them inbetween the y_values of 0-2. How would I scale this down? Either mathematically or a built-in matplotlib way. </p>
