You have no possibility to set double datalabels, but you can use workaround, which is not perfect but maybe will be helpful. So you can set useHTML, then in formater return two divs, first appropriate datalabel (outside) and second with inside. Then set id with counter which define each div's id as unique, then only what you need is set appropriate CSS. Example of position one datalabel is available here: http://jsfiddle.net/4RKF4/
您无法设置双数据标签，但您可以使用解决方法，这并不完美，但可能会有所帮助。所以你可以设置useHTML，然后在格式化程序中返回两个div，第一个是适当的数据标签（外部），第二个是内部。然后用计数器设置 id ，它将每个 div 的 id 定义为唯一的，然后只需要设置适当的 CSS。位置一数据标签的示例可在此处获得：http: //jsfiddle.net/4RKF4/
$(function () {

there is a easy work arround for it
有一个简单的工作围绕它
that is you overlay 2 pie with diferent datalabels
那就是你用不同的数据标签覆盖 2 个馅饼
$(function () {
// Create the chart
$('#container').highcharts({
chart: {
type: 'pie',
backgroundColor: 'rgba(0,0,0,0)',
y:100
},
title: {
text: 'sfs '
},
yAxis: {
title: {
text: ' '
}
},
plotOptions: {
pie: {
// y:1,
shadow: false,
// center: ['50%', '50%'],
borderWidth: 0,
showInLegend: false,
size: '80%',
innerSize: '60%'
,
data: [
['allo', 18],
['asdad', 14],
['asdad', 11],
['asdasd', 10],
['adad', 8],
['asdada', 7],
['adada ada', 7],
['adad', 5],
['asdas',7],
['ada', 3]
]
}
},
tooltip: {
valueSuffix: '%'
},
series: [
{
type: 'pie',
name: 'Browser share',
dataLabels: {
color:'white',
distance: -20,
formatter: function () {
if(this.percentage!=0) return Math.round(this.percentage) + '%';
}
}
},
{
type: 'pie',
name: 'Browser share',
dataLabels: {
connectorColor: 'grey',
color:'black',
// y:-10,
softConnector: false,
connectorWidth:1,
verticalAlign:'top',
distance: 20,
formatter: function () {
if(this.percentage!=0) return this.point.name;
}
}
}
]
});
});
