Are you looking for something that is grouped in threes (3 US bars, space, 3
EU bars, space, 3 Japan bars)? Or what? It would be helpful if you include
an example of what you would like from the spreadsheet program.
Btw, if you want space in between the three groups like I described above,
you can simply make the 'width' variable smaller (like 0.15).
