Highcharts甜甜圈百分比问题

Question

我正在尝试使用Highcharts进行可视化。我想改变外面的甜甜圈的价值观。值应以百分比表示。例如，如果y值为23，则数据值为11和12，但我想将它们显示为y（11 * 100/23）的百分比......是否可能？

代码

$(function () {
    var a = [];

    var colors = Highcharts.getOptions().colors,
        categories = ['pool_ipv4_02','pool_ipv4_03','pool_ipv6_02','pool_ipv6_03','pool_ipv4_01','pool_ipv6_01'],
        data = [{
            y: 13.45,
            color: colors[0],
            drilldown: {
                name: 'Pool1 Info',
                categories: ['Used', 'Free'],
                data: [12.73,0.72],
                color: colors[0]
            }
        }, {
            y: 20.38,
            color: colors[1],
            drilldown: {
                name: 'Pool2 Info',
                categories: ['Used', 'Free'],
                data: [14.03,6.35],
                color: colors[1]
            }
        }, {
            y: 24.03,
            color: colors[2],
            drilldown: {

            }
        }, {
            y: 11.77,
            color: colors[3],

        },{
