Single series drilldown to multiple series Highcha

问题:

I need to drill down from a series to multiple series. But the drilldown id seems to be unique on a series, implying that I can't drilldown to multiple series from a single series; just one. How do I get round this?

回答1:

It is possible to load series for drilldown in drilldown event using chart.addSingleSeriesAsDrilldown(e.point, series[0]); mulitple times with different series and next call chart.applyDrilldown();
