Sorting of Values in Clustered Bar Chart

Help Please!! 🙂

1. I am trying to sort the months and the values for each month but having difficulties? Tried sorting by month then by value and it seems does not respond accordingly.

2. When i do Top N filter, i noticed that it gets the top filter for the entirety but not for the particular month only. I supposedly want to get the top 5 for each month.

Thanks for those that will answer.
