我正在修改这个圆环图，需要删除中间并用文本替换它：

http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/pie-donut/

最好的方法是什么？

$(function () {

    var colors = Highcharts.getOptions().colors,
        categories = ['MSIE', 'Firefox', 'Chrome', 'Safari', 'Opera'],
        name = 'Browser brands',
        data = [{
                y: 55.11,
                color: colors[0],
                drilldown: {
                    name: 'MSIE versions',

要在图表中间获得空白空间，请使用“size”和“innerSize” - 就像在你的例子中一样：

            size: '80%',
            innerSize: '60%'

关于文本 - 我建议使用renderer.text()。
