title: Defining plot options once and call them for several subplots
body: <p>I am using several subplots. In these subplots data is plotted using <code>imshow</code>. The options I pass to <code>imshow</code> are identical for almost all of the subplots. However, they pollute my code due to the length of the options.</p>
  
  <p>The options I use include:</p>
  
  <ul>
  <li><code>extent</code></li>
  <li><code>cmap</code></li>
  <li><code>norm</code></li>
  <li><code>origin</code></li>
  <li><code>interpolation</code></li>
  </ul>
  
  <p>To have a better overview of my code I would like to define the options once and call them for each subplot. What is a pythonic way to do this?</p>
