You can create a calculated column or use filter to show data for last n days transactions.
Using calculated field- create as below
IF DATEDIFF('day',[Date],TODAY()) <N THEN [Date] END
Now drop the above field in visual to see the fields as per 10 last n days.
Using filter -
Drop the date in filter column and edit the filter as top N( for ex. 10) and select Last date where last date is a calculted field which has code MAX([Date]) to fetch the last N dates.
Hope it helps you.
