title: Formatting data points and Y-axis labels using HighCharts
body: <p>My data points consist of time spans expressed in seconds to two decimal places. However, for display purposes, I want these values to be formatted in minutes, seconds, and hundredths. For example, the value 125.78, should be displayed as 2:05.78 in the tooltip and the Y-axis labels should be formatted likewise.</p>
  
  <pre><code>$(function () {
      $('#container').highcharts({
          title: {
              text: '800 Meter times',
              x: -20 //center
          },
          xAxis: {
              categories: ['3/7', '3/14', '3/21', '3/28']
          },
          yAxis: {
              title: {
                  text: 'Times'
              },
              plotLines: [{
                  value: 0,
                  width: 1,
                  color: '#808080'
              }]
          },
          legend: {
              layout: 'vertical',
              align: 'right',
              verticalAlign: 'middle',
              borderWidth: 0
          },
          series: [{
              name: 'Joe Blow',
              data: [125.78, 125.12, 123.88, 124.06]
          }]
      });
  });
  </code></pre>
