title: Max & Min highchart line
body: <p>I'm trying to graphic some values, I have this part, then I want to add some <code>max and min</code> line, I could do this creating another series and adding the min/max value that I want, the problem here is that my value series is an array of <code>n elements</code> so I want to know if I could create the min/max series for example just doing <code>data: [2]</code> and put the line in all the width of my chart. Something like this:</p>

  <p>If there is no way to do this, just if is possible doing: <code>data[2, 2, 2,.... n]</code> is possible to show only the first and the last point and hide the rest of them?</p>
