鼠标悬停在海图中时隐藏折线图

我用HighChart绘制了两条线,当用户将鼠标移到绘图区域时,我需要隐藏一条线。有人能帮我吗? 下面是我尝试过的jsFiddle链接。

    },
    plotOptions: {
        series: {
            point: {
                events: {
                    mouseOver: function () {
                       console.log("mouse over");
                    }
                }
            },
            events: {
                mouseOut: function () {
                   console.log("mouse out");
                }
            }
        }
    },
series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],
        visible: true
    }, {
        data: [144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4, 29.9, 71.5, 106.4, 129.2]
