When setting filters in LookML or in the 'Add/edit Dashboard Filters . . ." modal, we can assign a default value for the filter. In both cases, Looker expects a string. Looker will interpret that string and, depending on the filter type (date, string, or number), change the filter menu drop down option for the end user. E.g. if I want to have a date filter on the dashboard automatically present as “in the past 90 days”, typing “90 days” as the default value will produce the desired behavior.
To get the desired dropdown here:
Type in the appropriate String Format from the tables below in your dashboard default value field here:
Or as the default parameter in your LookML filter like this:
LookML
filter: date_filter {
type: date
default_value: "6 weeks"
}
For more information, check out our documentation on Looker Filter Expressions.
