title: How to set Highcharts chart maximum yAxis value
body: <p>I've been trying for two days to find a way to set the <strong>maximum value</strong> of the yAxis on Highcharts.</p>
  
  <p>I got a percentage <strong>column graphic</strong>, but the highest value in the series is 60, so it adjusts the axis to <strong>top at 70</strong>, I found a way to <strong>choose the start point</strong>, but no way to <strong>choose the end point</strong>.</p>
  
  <p>What I really need is to set the <strong>yAxis from 0 to 100</strong>, so the data will be more accurately viewed as percentage</p>
  
  <p>Thanks in advance,
      Bruno W.G.</p>
