Nested Sort

Hi All,

Can someone please tell me how I would sort the bar by year by visa type in descending order. I wanted to sort the bars by year such that, for example, in FY16, 121 count should be at the top, followed by 43.. and so on. For FY17,89 should be at the top, followed by 28. How do I do a nested sort here or if there should a different approach, could you advise please?

Thanks, and I hope everyone is staying safe and healthy during these challenging times.
