title: How to add lines between individual data points?
body: <p>I'm trying to make a scatter plot in Highcharts that only connects two individual points to  each other, but doesn't connect to any other points. (To show the change in a data point over time). </p>
  
  <p><a href="http://jsfiddle.net/2MdEN/" rel="nofollow">Here</a> I illustrate my question. I'd like for there to be a line between the points</p>
  
  <p><code>[20, 20]</code> and <code>[80, 80]</code></p>
  
  <p>and a separate line connecting </p>
  
  <p><code>[60, 40]</code> to <code>[85, 60]</code></p>
  
  <p>but no line connecting </p>
  
  <p><code>[80, 80]</code> to <code>[60, 40]</code></p>
  
  <p>Is there an easily configurable way to do this, or do I have to manually render each line?</p>
