// 设置单色并为所有饼设置默认主题
Highcharts.getOptions().plotOptions.pie.colors = (function () {
   var colors = [];
   var base = Highcharts.getOptions().colors[0];
   var i;

   for (i = 0; i < 10; i += 1) {
      // 以一暗色开始并以亮色结束
      colors.push(Highcharts.Color(base).brighten((i - 3) / 7).get());
   }
   return colors;
}());
