title: minPadding doesn't work
body: <p>I have the <a href="http://jsfiddle.net/elias2012/b5Kkk/" rel="nofollow noreferrer">chart</a></p>
  
  <p>Now if data is equal 1 then the line is hard to see below image</p>
  
  <p><img src="https://i.stack.imgur.com/Srpet.jpg" alt="enter image description here"></p>
  
  <p>I write:</p>
  
  <pre><code>minPadding: 0.08,
  maxPadding: 0.08, 
  </code></pre>
  
  <p>but this doesn't work</p>
  
  <p>How to shift the graph down?</p>
