    • Whether a series is one of am5flow's weighted graphs.

      Asked only by the alluvial declaration, which is the one reading amCharts has no class for at all: an alluvial IS a sankey — the same weighted flow drawn without a left-to-right budget — so the only thing separating them is the author saying which they drew. This is the "wrong construct" half of that check: a block declaring an alluvial on a pie series is a mistake worth reporting, not a layer to emit with nothing in it.

      Parameters

      Returns boolean
