Extract DumbbellPoint data from a column series drawn as a barbell.
The same openValueY / valueY pair a waterfall uses, read as the two
values compared at one category rather than as a running total: which of the
two is larger is not fixed, and a chart usually holds both directions at
once.
The two ends are deliberately not named here. amCharts names the series, not
the ends, so anything read off the chart would be a guess; the adapter takes
them from an option instead, and the trace announces "start" and "end" when
it has nothing better.
