答案 2 :(得分：0)
我不知道这样做＆＃34; highcharts＆＃34;方式，但你可以用CSS做到这一点：
text {
text-decoration: none !important;
}
图表的内嵌代码为text-decoration: underline;，因此在这种情况下，您需要!important黑客来覆盖它。
这是一个嵌入式示例：
$(function () {
// Create the chart
$('#container').highcharts({
chart: {
type: 'pie'
},
title: {
text: 'Browser market shares. January, 2015 to May, 2015'
},
subtitle: {
text: 'Click the slices to view versions. Source: netmarketshare.com.'
},
plotOptions: {

dataLabels: {

}
}
