How to position rowgroup vertically instead of horizontally

[ktalarico]

According to the documentation, if you add a new row group, it should appear as in the below picture.  Note that Row group 2 header appears below Row group 1 header.

 

 When I attempt to add a rowgroup (called "QUAL"), it is positioned to the right of my second row group.  I want it to be positioned underneath row group 1 header (called "NAME").  How can I achieve this?

This is what it looks like now:

I've attached my source code.  Thank you to anyone who can help!

I solved my problem by changing the bucket expression for the NAME rowgroup to be $F{NAME} + "n" + $F{QUAL}
