为什么要在高图的传说中出现鼠标悬停事件？(why to get mouse out event in legend in highchart?)

https://plnkr.co/edit/JCOQa1vdqU9KBusqlOlL?p=preview嗨我做了一个简单的演示甜甜圈图表。我想在传说中获得mouseover事件和mouseout事件。我能够在甜甜圈切片上获得mouseover事件。它是工作得很好。我想在传说中使用相同的功能。我在传说中获得了mouseover事件，但是我的mouseout事件没有解除为什么？

$(chart.series[1].data).each(function(i, point) { $(point.legendItem.element).hover(function () { // on over for (var i = 0; i < chart.series[1].data.length; i++) { chart.series[1].data[i].update({ color: i === point.index ? point.options.origColor:'grey' }, false, false); } chart.series[1].chart.redraw(); }, function () { // on mouseout alert('--') }); });

在鼠标移出时，我想将其移动到原始/相同的状态
