If you want to pass additional data for a point other than the x and y values, then you have to name that value. In the following example I add the following three additional values to each data point:

{
  y: 3,
  locked: 1,
  unlocked: 1,
  potential: 1,
}

Then to access and display those values in the tooltip I use the following:

tooltip: 
{
     formatter: function() { return ' ' +
        'Locked: ' + this.point.locked + '<br />' +
        'Unlocked: ' + this.point.unlocked + '<br />' +
        'Potential: ' + this.point.potential;
     }
}
