I'm trying to develop a sankey chart for a current phone system process. I found a 5 step sankey template and prepped the data accordingly. That works fine but our process has 6 maximum steps. Therefore I followed the logic used to create all the existing steps and polygons in order to create one additional polygon and stage, however things are not appearing as expected. The polygon ends up as several straight lines and the steps in latter 2 stages appear to be shifted lower than expected. Can someone take a look and see what might be happening here?
