Highcharts 单色饼图 · W3School Highcharts 教程

# 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; }()); ``` ### 实例文件名：highcharts_pie_monochrome.htm ``` <html> <head> <title>Highcharts 教程 | 菜鸟教程(runoob.com)</title> <script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script> <script src="/try/demo_source/highcharts.js"></script> </head> <body> <div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div> <script language="JavaScript"> $(document).ready(function() { var chart = { plotBackgroundColor: null, plotBorderWidth: null, plotShadow: false }; var title = { text: 'Browser market shares at a specific website, 2014' }; var tooltip = { pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>' }; var plotOptions = { pie: { allowPointSelect: true, cursor: 'pointer', dataLabels: { enabled: true, format: '<b>{point.name}%</b>: {point.percentage:.1f} %', style: { color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black' } } } }; var series= [{ type: 'pie', name: 'Browser share', data: [ ['Firefox', 45.0], ['IE', 26.8], { name: 'Chrome', y: 12.8, sliced: true, selected: true }, ['Safari', 8.5], ['Opera', 6.2], ['Others', 0.7] ] }]; // Make monochrome colors and set them as default for all pies Highcharts.getOptions().plotOptions.pie.colors = (function () { var colors = []; var base = Highcharts.getOptions().colors[0]; var i; for (i = 0; i < 10; i += 1) { // Start out with a darkened base color (negative brighten), and end // up with a much brighter color colors.push(Highcharts.Color(base).brighten((i - 3) / 7).get()); } return colors; }()); var json = {}; json.chart = chart; json.title = title; json.tooltip = tooltip; json.series = series; json.plotOptions = plotOptions; $('#container').highcharts(json); }); </script> </body> </html> ``` 以上实例输出结果为： ![](https://box.kancloud.cn/2015-12-29_5682517bba2b5.png)
