本文实例讲述了jQuery插件HighCharts绘制2D圆环图效果。分享给大家供大家参考，具体如下：
1、实例代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>HighCharts 2D圆环图</title>
<script type="text/javascript" src="js/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="js/highcharts.js"></script>
<script type="text/javascript">
$(function(){
var colors = Highcharts.getOptions().colors,
categories = ['花', '树', '鱼', '鸟', '鲸'],
name = 'Browser brands',
data = [{
y: 55.11,
color: colors[0],
drilldown: {
name: '花的种类',
categories: ['梅花', '桃花', '梨花', '樱花'],
data: [13.6, 7.35, 33.06, 2.81],

}
}, {
y: 2.14,
color: colors[4],
drilldown: {
name: '鲸的种类',
categories: ['须鲸', '蓝鲸', '虎鲸'],
data: [ 24.12, 18.37, 32.65],
color: colors[4]
}
}];
// 构建物种数据
var speciesData = [];
var speData = [];
for (var i = 0; i < data.length; i++) {
// 添加物种数据
speciesData.push({
name: categories[i],
y: data[i].y,
color: data[i].color
});
for (var j = 0; j < data[i].drilldown.data.length; j++) {
var brightness = 0.4 - (j / data[i].drilldown.data.length) / 5 ;
speData.push({
name: data[i].drilldown.categories[j],
y: data[i].drilldown.data[j],
color: Highcharts.Color(data[i].color).brighten(brightness).get()
});
}
}
// 创建圆环图
$('#donutChart').highcharts({
chart: {
type: 'pie'
},
title: {
text: '物种数量及其比例'
},
yAxis: {
title: {
text: '比例'
}
},
plotOptions: {
pie: {
shadow: true,
center: ['50%', '50%']
}
},
tooltip: {
valueSuffix: '%'
},
series: [{
name: '物种',
data: speciesData,
size: '70%',
dataLabels: {
formatter: function() {
return this.y > 5 ? this.point.name : null;
},
color: 'white',
distance: -30
}
}, {
name: '数量',
data: speData,
size: '80%',
innerSize: '80%',
dataLabels: {
formatter: function() {
return this.y > 1 ? '<b>'+ this.point.name +':</b> '+ this.y +'%' : null;
}
}
}]
});
});
</script>
</head>
