Welcome to the forum! I think you’ll find this to be a great resource and a really helpful community.
I think the solution here is just to sort your x-axis by the fiscal year column in your date table (also be sure that your date table is marked as a date table, so that the time intelligence functions work properly). Here are a couple of forum posts that address similar questions.
If these don’t solve your problem, please post your PBIX file so that I can provide a more specific solution.
