Instead of floating, I have used tiled layout to align them properly. I am not sure if this is what you are looking for. Please see the workbook attached. HTH
Sankey Trail_modified.twbx 1.2 MB
Thank you for helping out!
Although my issue is something different and I apologise for not making it clear.
What I meant was, the curve in the sankey chart is not aligned with the bar charts. Ideally if the bar on the left side has elements inthe order: Furniture, Office Supplies and Technology, but the sankey's curve starts with Technology, officce supplies, and furniture and its the same issue with the right bar as well.
Also the curve of the sankey seems to be falling to the bottom and the left side of the curve is spread over the graph.
I have been trying to see the table calculations along which bar level is has been calculated but not able to find the issue.
