title: Background color for Jqplot pie chart
body: <p>Kindly i have a page and in the page i have two pie charts,
   i want to display different background color for the 2 charts but it is embeded in the css file!
   is there any option to use any color?? or to make it transparent?
   my code:</p>
  
  <pre><code> PieTimer[index] = jQuery.jqplot(PieTimerId,
  
   TimerValuesArray,
   {
   seriesDefaults: {
  
   shadow: false,
  
   seriesColors: ["#13e837", "#6e869b"],
  
   renderer: jQuery.jqplot.PieRenderer,
  
   rendererOptions: {
  
   highlightMouseOver: false,
  
   diameter: 40,
  
   padding: 0,
  
   showDataLabels: false,
  
  startAngle: 270,
  sliceMargin: 0,
  
  shadowOffset: 0,
  
  shadowAlpha: 0,
  
  
  shadowDepth: 0,
  
   drawBorder: false,
  
   shadow: false,
  
   borderWidth: 0
  
   }
  
   },
  
   legend: { show: false, location: 'w'}
  
   }
  
   );
  </code></pre>
  
  <p>i'm wondering if i can set a property (ex: backgroundcolor ...) when drawing the chart?
