title: Trying to plot a colormap in python
body: <p>So I'm trying to plot a colormap in python, not really sure how to go about doing it. At this point, I don't really care what colors are used, I'd just like them to be in a 10x10 grid. I've toyed around with matplotlib.pyplot.hist2d, but I'm not familiar enough with the arguments or plotting in general to get it to work.</p>
  
  <p>This is what I want it to look like: <a href="http://i.stack.imgur.com/zKEFm.png" rel="nofollow">http://i.stack.imgur.com/zKEFm.png</a></p>
  
  <p>Any help would be greatly appreciated!</p>
  
  <p>Here are my values:</p>
  
  <p>x = [1000.0, 1500.0, 2000.0, 2500.0, 3000.0, 3500.0, 4000.0, 4500.0, 5000.0, 5500.0]</p>
  
  <p>y = [50.0, 100.0, 150.0, 200.0, 250.0, 300.0, 350.0, 400.0, 450.0, 500.0]</p>
