title: Google line chart fill a data line
body: <p>I have this google line chart but want to fill one line like an area chart. I looked on google and it seems their syntax for this is very different to the code used to create charts - i simply dont get it. Heres my chart options:</p>
  
  <pre><code>var l1=new google.visualization.LineChart($('l1'))
  l1.draw(d,{
  width:900
  ,height:280
  ,fontSize:11
  ,legend:{position:'right'}
  ,pointSize:2
  ,chartArea:{left:35,top:8,width:'80%',height:220}
  ,backgroundColor:"#DDDDDD"
  ,colors:["blue","green","yellow","orange","red"]
  ,hAxis:{textPosition:'out'
  ,slantedText:true},
  series:{0:{color:'#BBBBBB',lineWidth:10},1:{color:'#CCCCCC',lineWidth:10},2:{color:'yellow'},3:{color:'orange'},4:{color:'red'}}
  })
  </code></pre>
