Highcharts：如何在创建图表后设置图例标签名称？

Question

I need to change dynamically legend labels and I was surprised when I have not found method like chart.legend.setLabels()

I tried this

chart.legend.allItems[0].name = 'bla bla'
chart.legend.redraw()

nothing happend

tried to change options

chart.options.legend.labels[0].name = 'bla bla'
chart.redraw()

nothing happend

So is there way to change legend label name?

Answer 1

You can use update() function

 chart.legend.allItems[0].update({name:'aaa'});
