title: Inverting rows and columns on Google Area Chart
body: <p>When I use an Area Chart on Google Drive, I can select an option to "Switch Rows / Columns". </p>
  
  <p>Now that I am playing with the Javascript API, I'd like to do the same but couldn't find a way to do it in the documentation. </p>
  
  <p>Here's the code I am using successfully. All I need is to switch row/column on the API.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  google.load("visualization", "1", {packages:["corechart"]});
  google.setOnLoadCallback(drawChart);
  function drawChart() {
  
  var data = google.visualization.arrayToDataTable([
  ['data',0,1,2,3,4,5,6]
  ,['2013-04-14 (336)',064,04,03,02,06,02,02]
  ,['2013-04-21 (169)',0,028,03,02,04,02,02]
  ,['2013-04-28 (121)',0,0,027,02,01,02,02]
  ,['2013-05-05 (101)',0,0,0,020,0,01,0]
  ,['2013-05-12 (688)',0,0,0,0,0143,017,07]
  ,['2013-05-19 (3226)',0,0,0,0,0,0642,022]
  ,['2013-05-26 (321)',0,0,0,0,0,0,082]
  ]);
  
  var options = {
  title: 'Company Performance', isStacked:true,
  hAxis: {title: 'Year', titleTextStyle: {color: 'red'}}
  };
  
  var chart = new google.visualization.AreaChart(document.getElementById('chart_div'));
  chart.draw(data, options);
  }
  &lt;/script&gt;
  </code></pre>
  
  <p>Can anyone help?</p>
