Extract WaterfallPoint data from a column series drawn as a bridge.
The bar floats between the running total before the step and the total after
it, which is the pair amCharts keeps in openValueY / valueY. Both are
carried, plus the contribution between them: a bar chart would conflate the
two, and "how big was this step" and "where did it leave us" are different
questions.
