Highcharts 饼图Highcharts 饼图

以下实例演示了渐变饼图。

我们在前面的章节已经了解了 Highcharts 基本配置语法。接下来让我们来看下其他的配置。

配置

colors 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
      ]
   };
});
