title: How to add or change an axis to an image in python?
body: <p>I am attempting python for the first time.  My end game have an image with an x-axis of distance in meters and a y-scale of depth (m) showing a 500x500m grid.
  I was able to plot the grid onto the image two different ways, both ways utilize pixel size for the grid spacing themselves.  A simple distance to pixel ratio is used to get accurate grid spacing.</p>
  
  <p>The first attempt (using matplotlib), I was able to create an accurate grid spacing with incorrect axes (the axes reflect pixels, no clue how to change the axes values without changing grid spacing).</p>
  
  <p>The second code (using PIL) produces an Image with only grids and no axes at all, only grids</p>
  
  <p>Im sure the answer to my problem is buried inside the PIL or matplotlib documentation, but I am new to python and am still learning the conventions , and even how libraries work </p>
  
  <p>Is there a way to draw axes around an image?  Or would it simply be easier to make a custom scale that does not relate to pixels somehow with matplotlib? </p>
  
  <p>I know this is a very vague question, but could someone point me in the right direction?</p>
  
  <p>Thanks!</p>
