下图是一个 Highcharts 渐变饼图

配置

使用 Highcharts.getOptions().colors 属性来配置颜色。

//颜色的填充
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function (color) {
   return {
      radialGradient: { cx: 0.5, cy: 0.3, r: 0.7 },
      stops: [
         [0, color],
         [1, Highcharts.Color(color).brighten(-0.3).get('rgb')] // darken
      ]
   };
});
