jqplot如何实现在图表外用线条显示标签？

Answer 1

dataLabelPositionFactor 控制标签在切片上的位置。增加将使标签向饼图边缘滑动，减少将使标签向饼图中心滑动。

dataLabelPositionFactor : 1.2,

默认 dataLabelThreshold 值为 3，因此不显示值 <=3，因此将其设置为 0

数据标签阈值:0

 $(document).ready(function(){
  var data = [
    ['Heavy Industry', 12],['Retail', 9], ['Light Industry', 14], 
    ['Out of home', 16],['Commuting', 7], ['Orientation', 9]
  ];
  var plot1 = jQuery.jqplot ('chart1', [data], 
    { 
      seriesDefaults: {
        // Make this a pie chart.
        renderer: jQuery.jqplot.PieRenderer, 
        rendererOptions: {
          // Put data labels on the pie slices.
          // By default, labels show the percentage of the slice.
          showDataLabels: true, 
         //dataLabelPositionFactor controls position of label on slice.  Increasing will slide label toward edge of pie, decreasing will slide label toward center of pie.
         dataLabelPositionFactor : 1.2,
         // default dataLabelThreshold  value is 3,  hence values <=3 are not displayed hence make it to 0
         dataLabelThreshold : 0
        }
      }, 
      legend: { show:true, location: 'e' }
    }
  );
});
