title: HighCharts: draw multiple segments in a single serie?
body: <p>i'm asking myself if it's possible to do multiple lines (in a single serie) that are overlapping.
  I  couldn't find any example for that :(</p>
  
  <p>I don't want this: <a href="https://stackoverflow.com/questions/23242857/highcharts-highstock-step-line-without-vertical-transition-lines">Highcharts / Highstock step line without vertical &quot;transition&quot; lines?</a></p>
  
  <p>If i have a set of value like that: </p>
  
  <pre><code>serie1 = [
       [{x:5, y: 10}, {x:7, y: 10}], # segment 1
       [{x:2, y: 12}, {x:9, y: 12}], # segment 2
  
  ] 
  </code></pre>
  
  <p>I want to plot both lines which are in the same series so i can benefit from the interactivity (legend for example).     </p>
  
  <pre><code> y
   ^ 
   |
   |    ------------------segment2-------------------
   |           -----------segment1-------------
   |
   |---2-------5-------------------------------7-----9----------&gt; x
          ______________________
          |                    |
          | Legend: - serie 1  |
          |____________________|                (I'm proud of my ASCII skills ! :D)
  </code></pre>
  
  <p>Is this possible ? Thanks</p>
