title: Highchart: show seconday y-axis tick positions 0 to 12
body: <p>I'm outputting a series of high charts on a page. In this chart used secondary y-axis for essay. I used </p>
  
  <pre><code>tickPositions: [0,3,6,9,12]
  </code></pre>
  
  <p>(<a href="http://jsfiddle.net/AT32j/3/" rel="nofollow">http://jsfiddle.net/AT32j/3/</a>) but in that chart scales are stretched and displayed 3,12 scales only.</p>
  
  <p>How to display secondary y-axis within this tick-positions (0,3,6,9,12)?</p>
