title: jqPlot mouseOver on pie chart
body: <p>I am using jqplot version 1.0.8r1250 and I can't figure out how to get the mouseOver event to work on the pie chart slice. The normal seriesColors work fine though.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>$.jqplot('pieChart', [pieChartData],
  {
     seriesColors: [color1, color2, color3, color4],
      grid: {
               background:'#FFFFFF',
               borderWidth:0,
               shadow:0
             },
  
       seriesDefaults: {
                          renderer: $.jqplot.PieRenderer,
                          rendererOptions: {
                                             highlightMouseOver: true,
                                             highlightMouseDown: false,
                                             highlightColor:  [hoverColor1, 
                                                               hoverColor2,
                                                                hoverColor3,
                                                               hoverColor4],
                                                  },
                                              },
                               legend: {
                                          show: true, 
                                          location: 'e'
                                      },
  
                          });
  </code></pre>
