First question here!
I'm trying to create a chart (with drill down) in High Charts that should look like this:

When you click on a year column it should drill down to the following (month view)
https://www.dropbox.com/s/2cji7a534wmwt2u/month.png
One of my problems is that each column in the drill down should, how to put it, have two (multiple) columns. For example, the month view (the drill down) should have 2 columns per month (current & previous month).
I just have no clue about how to design this chart in regards to series data etc etc.
Have looked thru just about every relevant High Charts example I have been able to dig up on the net.
Regards
Joakim
