good tutorial. thanks
Is there a similar way to filter diagrams or charts as well ?

[@furkansimsek33]

Thank you for the tip. I am looking forward to learning more Power BI tips from Pragmatic Works :)

[@kebincui]

Great tip👍. Thanks

[@seanguerrero1187]

Thanks for sharing this great tip, Mitchell! Will this also help in reducing the lag time it takes in creating/editing measures since now there would be less data to work with?

[@shoaibrehman9988]

Yes indeed its gr8 tip.

[@jhormangomez2268]

Totally agreed, also common sense

Mitchell, thanks for this very useful tip. I find parameters to be a great tool but I noticed that coding the date at the parameter level minimizes the number of instances where to update a date change in the future, however, it still creates a dependency on the user to remember in the future to change the base date used to filter the dataset. Would it be possible to create a dynamic parameter that would use a formula such as > the previous 12 months, etc.? If so, could you show us how to do it? Thanks!

hi Mamuel, you can create a parameter (e.g. MonthsBackParameter of how many previous months you want the data to be filtered and then you use the code below to get the data filtered dynamically:
= Table.SelectRows( #"Previous Step", each [Your Date Column] >= Date.StartOfMonth(Date.AddMonths(DateTime.Date(DateTime.LocalNow()), - (MonthsBackParameter-1) )))
