Define 13 Last Month with String Data

How to define on chart to showing last 13 month? On current data i don’t have “date column” (month as string, year as string)

Hi @ringgo

You can create a calculated field that combines ‘month’ and ‘year’ strings and produce a ‘Date’ value; For example, consider ‘month’ and ‘year’ fields having the following values:

month year
JAN 2020
FEB 2020
MAR 2020

you can create a calculated field with the following expression that will produce a date value:

You can then use this new calculated field to filter for last ‘N’ months.
