   <p>With the threshold plugin, you can apply a specific color to
   the part of a data series below a threshold. This is can be useful
   for highlighting negative values, e.g. when displaying net results
   or what's in stock.</p>

   <p class="controls">
   <input type="button" value="Threshold at 5">
   <input type="button" value="Threshold at 0">
   <input type="button" value="Threshold at -2.5">
   </p>
