title: Matlab: mirror results along xaxis
body: <p>I can't seem to find any documentation explaining how to mirror my matlab results. </p>
  
  <p>ie I have this:</p>
  
  <p><img src="https://i.stack.imgur.com/SAb2p.png" alt="enter image description here"></p>
  
  <p>and I want my results to be upside down....</p>
  
  <p>using <code>set(gca, 'XDir', 'reverse')</code> and <code>set(gca, 'XDir', 'reverse'Y</code> do not work for me ( I am using figue and quiver to plot)</p>
