I followed your suggestion to maximize the visualization screen, and it did showed up, but not in what I'd expected. I'd expect that the month dimension in time hierarchy would showed up as month numbers, not month labels. Or at least we could get an option in what format it can be shown, cause it sure does not look pretty and ate too many space.
Is there any way so the month dimension in time characteristic would show up as month number instead of month name/label?
