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 ] };});实例
