title: Y labels are not shown fully when using setVisibleYRangeMinimum in ios Charts
body: <p>I'm using <a href="https://github.com/danielgindi/Charts" rel="nofollow noreferrer">https://github.com/danielgindi/Charts</a> and having troubles getting setVisibleYRangeMinimum to work properly. I expect it not only to zoom out to minimum range but also to display all the labels on Y axis.</p>
  
  <p>Here's my code snippet:</p>
  
  <pre><code>data.addDataSet(set1)
  wrapperGraphView.data = data
  wrapperGraphView.setVisibleYRangeMinimum(300, axis: .left)
  wrapperGraphView.notifyDataSetChanged()
  </code></pre>
  
  <p>Here's the result:
  <a href="https://i.stack.imgur.com/q7BCN.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/q7BCN.jpg" alt="result"></a></p>
  
  <p>It's zooming out properly, but does not display all the labels up to 300 on Y axis.</p>
  
  <p>Any suggestions would be appreciated.</p>
