推荐答案

您可以在第一个mouseOver事件中添加其他系列，然后更新其数据.例如:

You can add an additional series in the first mouseOver event and then update its data. For example:

series: [{
    data: [...],
    point: {
        events: {
            mouseOver: function() {
                var chart = this.series.chart;

                if (!chart.series[1]) {
                    chart.addSeries({
                        data: additionalData[this.index].slice()
                    });

                } else {
                    chart.series[1].setData(
                        additionalData[this.index].slice()
                    );
                }

            }
        }
    }
}]
