Could you please attach TWBX, not TWB.
As a starting point, if you haven't already done so, try reading https://onlinehelp.tableau.com/current/pro/desktop/en-us/help.html#multiple_measures.html - I think you'll be looking at creating a dual axis
If this doesn't help, then as Shin suggests, please include a TWBX file (a packaged workbook).
Hi William - any update/feedback on this? Have you managed to acheive what you needed? If any of the above helped, then please mark as correct answer, so the thread can be closed down.
