Hello,
I am attempting to create a temporal line chart with drilldown.
The issue I am currently facing is that I can't put more than one line series in the drilldown.
This is an example that I've found in a post of 2015 by the developer Grzegorz, which has exactly the same issue that I have:

If I click in the Asia (blue) line, the drilldown is expected to have four series: Japan, South Korea, China and Thailand, but only the Japan line is showing.
Does anyone know how to make all the lines appear in the drilldown?
