Whether two column series are drawn back to back across a shared axis — a
population pyramid, or a Likert scale split around a neutral midpoint.
amCharts has no diverging series: the chart is two ordinary column series
on one category axis with one side's values negated, which is otherwise the
signature of a dodged bar chart. What separates them is the sign — one
series entirely on each side of the baseline, over the same categories in
the same order — and that is a statement about the data rather than about
how it was drawn, so it is decisive where a styling probe would not be.
Both sides must actually reach their side of the baseline: a pair of series
that are merely non-negative is every dodged bar chart ever drawn.
