Sorting/filter data by particular month in line chart

Hello all, I have a query about sorting data in a particular month in line chart. Line chart is showing a series of data, example as below. At the moment, my top 5 item groups are sorted by total value of item groups. What if at each month, I need to sort the data in descending order for that particular month, how do I do it in filter or DAX? It’s easy in excel by just sorting a particular column, but I don’t know how to do it in Power BI. As I’m sorting item group orders at each month, which means my top 5 item groups will be different as at each month.
