title: Change first tick label on yAxis
body: <p>I need change first tick label on yAxis. I changed the minimum value on the yAxis:</p>
  
  <pre><code>yAxis: [{
      title : {
          text : 'Position'
      },
      gridLineWidth: 1,
      startOnTick: false, 
      min: 1, //changed min value
      reversed: true,
  }]
  </code></pre>
  
  <p>but the value is not shown in front yAxis. How to sign the first value in the yAxis?</p>
  
  <p>Here's my <a href="http://test.shtalber.ru/charts/chart2.php" rel="nofollow">chart</a>.  </p>
  
  <p>if I write:</p>
  
  <pre><code>yAxis: [{
      title : {
      text : 'Позиция'
      },
      startOnTick: false, 
      showFirstLabel: true,
      min: 1,
      reversed: true, 
      tickInterval: 1,
      labels: {
            formatter: function() {
              if (this.value &lt; 1)
                  return null;
              else if (this.value == 1)
                  return this.value;
              else if (this.value % 2 == 0)
                      return this.value;
          }
      }
  </code></pre>
  
  <p>}]
  then scaling yAxis turns bad for my data :( <a href="http://test.shtalber.ru/charts/chart.php" rel="nofollow">chart</a></p>
