title: How can you access and style an individual line in G. Raphael line chart
body: <p>Due to the very poorly documented raphael JS library, I beseech the collective wisdom.</p>
  
  <p>I have a working g. raphael multi-line line chart (similar to <a href="http://g.raphaeljs.com/linechart.html" rel="nofollow">http://g.raphaeljs.com/linechart.html</a>)</p>
  
  <p>something like: 
  var lineChart = r.g.linechart(10,10,300,220,[1,2,3,4,5],[[10,20,15,35,30],[5,10,5,15,20]], {shade:true, "colors":["#44F","#CCC"], nostroke:true});</p>
  
  <p>I'd like to change one of the lines to set the fill = clear and stroke = a color</p>
  
  <p>I was told something like this would work, but no luck -any suggestions?
  lineChart.lines[0].attr({stroke: "#000"}),</p>
  
  <p>for extra credit, how can I set the fills of a line to a gradient?</p>
  
  <p>thanks!</p>
