Hi Tim Aardenburg,
Interesting, have you rad the following article?
Their Sankey has much wider lines that you could use

Thanks for the reply.
I have looked at that post, the problem there being that they build their lines from polygons which is better in terms of formatting and performance but will take some editing of the data outside of Tableau, which is not a possibility for me (the sankey has to be dynamic). I also doubt if that post takes into account the ID's that are nulls in the other Quarter.
I was able to somewhat solve the issue by drawing a line for each rowID, this solves the size formatting problem but makes everything as slow as swimming through ketchup.
I'll make this another personal project for the next quarterly report (it "works" for now) maybe at that point Tableau or my skills will allow for a more elegant solution to this issue.
Greetings and salutations,
