如何删除高图基本折线图中动态添加的系列

Question

我可以使用此方法将新系列添加到图表中：

chart.addSeries({
name: 'New Series',
data: [551,233,3233]
});

但我找不到删除它的方法。API中没有removeSeries或deleteSeries函数。我该怎么做？

以下是代码片段：

window.chart = Highcharts.chart('container', {
title: {
text: 'U.S Solar Employment Growth by Job Category, 2010-2020'
},
subtitle: {
text: 'Source: <a href="https://irecusa.org/programs/solar-jobs-census/" target="_blank">IREC</a>'
},
yAxis: {
title: {
text: 'Number of Employees'
}
},
xAxis: {

}
},

verticalAlign: 'middle'
},

});
})

没有任何特殊的API方法来删除该系列，但您可以使用普通的JavaScriptremove()方法来实现这一点。

chart.series[index].remove();
