Highcharts在动态highcharts中未定义

Question

I am passing some json data from some functions to function live(data) and its also being called after every two seconds by a function with data="".But I am getting this chart var declared on line 217 as undefined. help will be appreciated:)

Answer 1

The this keyword refers to the chart inside load callback.

So change to:

var length = this.series.length;
