title: Using jqPlot to fill the bottom half of a graph with a color
body: <p>I'm using jqPlot to make a simple graph:</p>
  
  <p><img src="https://i.stack.imgur.com/IJLeF.jpg" alt="enter image description here"></p>
  
  <p>Their documentation states that it's very out of date. Is there a way to shade the lower half of the graph (below the line) with a color such as this one?</p>

  <p>If not, any clues on how I could shade it myself? jqPlot uses javascript to draw on an HTML canvas.</p>
