There is no method for doing this in the API. You could remove the series and add it again with another name, but that will make the animations run a second time and I think it will be colored with a new color as well.
API 中没有执行此操作的方法。您可以删除该系列并使用另一个名称再次添加它，但这将使动画第二次运行，我认为它也将使用新颜色进行着色。

actually, there's a way now. In highchars 3.0 series added a new api, called update:
实际上，现在有办法了。在 highchars 3.0 系列中添加了一个新的 api，称为 update：
chart.series[0].update({name:"name u want to change"}, false);
chart.redraw();
it will not only update the series name below the chart, but the name in tooltip as well.
它不仅会更新图表下方的系列名称，还会更新工具提示中的名称。
Cheers!
干杯!

This seems to work :
这似乎有效：
chart.series[1].name="Renamed";
chart.redraw();

It is not required to Redraw chart again We can include it along with the series option in the Chart declaration as below:
不需要再次重绘图表我们可以将其与系列选项一起包含在图表声明中，如下所示：
var chart = new Highcharts.Chart({
chart: {
renderTo: 'high_container'
},title: {
text: 'IO Signal Data'
},subtitle: {
text: 'Source: GPS Modem'
},
yAxis: {
title: {
text: 'Value'
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle'
},
xAxis: {
type: 'datetime',
labels: {
enabled: true,
formatter: function () { return ddd[this.value][0]; }, //<=== the value to plot chart
}
},
series: [{
data: ddd,
name: SeriesName
}]
});
