Period Analysis Past Quarter data

[BIDevSonu]

Need help in getting past 4 quarters of data based on the filter selection on dashboard.

In the source table, we have data at quarter level ( have Year and Quarter column with other measures)

Example:
Year  Quarter Orders
2019  1        100
2019  2        200
2019  3        50
2019  4        90
2020  1        300

On the dashboard, have a filter in which user will select the Quarter ( this filter will have values like 2019Q1,2019Q2 so on which utilizes a dimension built using Year and Quarter)
Once the user selects the Quarter, then the visualization should only show past 4 quarters of data.

New to looker, any help here would be appreciated.
