单色饼图

Highcharts 饼图Highcharts 饼图

以下实例演示了单色饼图。

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().plotOptions.pie.colors 属性来配置每个饼的颜色。

// 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;
}());
