Controlling position of nodes in Sankey diagram

[Anthony Hsiao]

Hi there,

does anyone know if there is a way to control the vertical (or even horizontal) position of nodes in a Sankey diagram? Right now, it 'automatically' positions nodes in a specific way, and I'm trying to have a specific order of nodes to maintain consistency.

Concretely, I'm using the Sankey chart to display the flow of 'things' through a process over time, and for each interval, I want the nodes to have the same order.

Is that at all possible using Google charts, and if not, does anyone know of a Sankey or similar diagram that would allow for this? For reference, the kind of diagram I'm trying to create should be as close an approximation as possible to this sales pipeline chart: https://3.bp.blogspot.com/-UJnsdS6VkkE/V28OMpE3v5I/AAAAAAAAAgM/I3dw_T9FmIsiCrxbbGeHqc81M5ZlZ8VnQCLcB/s1600/PipelineVizStep2.png
