Bar chart - create category & sub category on same axis

[#1]

I have a question regarding bar charts.  Is it possible to have 2 dimensions on the same axis where one dimension is basically a sub category of the other dimension?  Similar to the attached example. 

Thanks,

Seth

You need one extra dummy expression to reflect the same. See the attached sample.

Also deactivate expression as legend in the bottom for dummy expression..
