title: Set color of Highcharts series bar based on value
body: <p>I have <a href="http://plnkr.co/edit/w0fKrvLbcQndqj0gl1bh?p=preview" rel="nofollow">this plunker</a> where I am playing with Highcharts. I was wondering if it was possible to set the color of a bar based on the value of that bar. Right now I have 5 bars that are changing on an interval between 0 and 100, and I want the colors of the bars to reflect the number range they are in. Like </p>
  
  <p><code>0 &lt; x &lt; 25</code> is neutral color</p>
  
  <p><code>25 &lt; x &lt; 50</code> is yellow</p>
  
  <p><code>50 &lt; x &lt; 75</code> is orange</p>
  
  <p><code>75 &lt; x &lt; 100</code> is red</p>
  
  <p>I am familiar with the series methods in the api, but I dont really see anything about changing the color for the series. I have previously done this using chart js but I am trying my hand at highcharts since it is used more.</p>
