title: How to increase the physical size of axes in matplotlib pyplot?
body: <p>I am plotting the following graph,
  <a href="https://i.stack.imgur.com/Ms9O9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ms9O9.png" alt="Graph plotted"></a></p>
  
  <p>I would like to change the physical size of the axes. I have plotted the xticks in hopes of being able to increase the spacing between them and thus increase the physical size of the axes, but no luck. I want a resulting image, that is possibly very large, but when zoomed in, I am able to see individual points and the arrows plotted. I tried changing the size of the figure, but it just creates a larger image, with higher resolution, and same level of detail as before, it does not allow me to see more points when I zoom in.</p>
  
  <p>Can someone please tell me how can I increase the physical size of the axes so when I zoom in on the saved image (right now I'm saving it in a pdf format) I can see individual points? Thanks so much</p>
