title: Interactive matplotlib plot with two sliders
body: <p>I used <strong>matplotlib</strong> to create some plot, which depends on 8 variables. I would like to study how the plot changes when I change some of them. I created some script that calls the <strong>matplotlib</strong> one and generates different snapshots that later I convert into a movie, it is not bad, but a bit clumsy. </p>
  
  <ol>
  <li><p>I wonder if somehow I could interact with the plot regeneration using keyboard keys to increase / decrease values of some of the variables and see instantly how the plot changes. </p></li>
  <li><p>What is the best approach for this? </p></li>
  <li><p>Also if you can point me to interesting links or a link with a plot example with just two sliders?</p></li>
  </ol>
