charts - HighCharts - 饼图半圆(图表中的箭头)

Question

我一直在尝试在半圆 donut chart 中插入箭头(就像速度计一样)

什么都试过了，但对我来说没有结果

这就是我想做的事情

我创建了 jsfiddle.net/ymf2zzn1/来演示我的问题

$(function () {
    $('#container').highcharts({
        chart: {
            renderTo: 'container',
            plotBackgroundColor: null,
            plotBackgroundImage: null,
            plotBorderWidth: 0,
            plotShadow: false
        },
        title: {
            text: 'Browser<br>shares<br>2015',
            align: 'center',
            verticalAlign: 'top',
            y: 40
        },
        tooltip: {
            pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
        },
		yAxis: [{

您可以使用两个系列 - 一个用于饼图，另一个用于角规。
