ascending drilldown with stacked bar chart

[rafalS]

Of course, it can't loop "forEach" through this.drilldowns, because it doesn't exist. You have normal array drilldown without this.

I edited your code, but it really wasn't related to Highcharts but normal array sorting, so next time do not put your question here on this forum but on StackOverflow forum.

One more tip for the future - try to use english words for naming your variables. I had spent 20 minutes before I figured out why my code isn't working and then I realized that it wasn't month variable but bulan.
