The description is "The last 30days". But Now I have a year, month and day filter. I want now build a dynamic description. Default it should stands "The last 30days". But when I'm selecting months, or days they are in a row and directly behind today it should stand "the last xy months" , "the last xy days". When I'm selecting only one month or day it should only stand the day, month name. When I'm selectin a month or day they are not directly behind each other for example May, August then it should stands "May, August".
