Highcharts 单色饼图
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; }());
