title: Plotting seconds, minutes and hours on the yAxis with Highcharts
body: <p>I have some data that looks like this:</p>
  
  <blockquote>
    <p>min="00:09" med="03:11" mean="23:39" max="12:40:26"</p>
  </blockquote>
  
  <p>I'd like to be able to be able to use these values as datapoints but I'm not sure how to plot them as they are not simple integers. Ideally I'd like to have the labels on the Y axis show something like 'hours' or if I was to use multiple y axes then it could show 'seconds' for the 'min' values, 'minutes' for the 'mean' values and so on adapting to the appropriate time window.</p>
  
  <p>I'm not sure if I can use datetime objects as I only have a time value and not a date.</p>
  
  <p>Any ideas will be appreciated and thanks in advance.</p>
