title: How to add an item to Highcharts legend?
body: <p>I have a graph with two series: <code>column</code> and <code>spline</code>. Programatically I changed the color of some columns that met some criteria, let's say the 10 lowest scores are rendered in  green, while the rest is blue.</p>
  
  <p>Now, in the legend, I have the series names, but it shows, obviously, the spline series name and the column series name in the default blue color. I want to know how to add a name to the legend for the columns that are rendered in green that says "lowest scores" for example.</p>
  
  <p>EDIT:</p>
  
  <p>The code for the series:</p>
  
  <pre><code>series: [{
