When building a dashboard you can configure any number of filters, to be applied as needed on any card included in the page.
Regular users usually are just interested in analyzing data, not designing pages, modeling data or configuring filters. Using filters is just as easy as clicking on them, and a dialog pops up to configure the filter.
Depending on the field data type associated with the filter, different options will appear on screen, allowing you to:
Select option values (all values, none, some values)
Use regular expressions (equals, not equals, greater than, between, etc.)
Use predefined values (this year, last 3 months, etc.)
Perform Top / Bottom calculated values
Defining filters in cards is recommended when as a business user it’s always needed to apply certain restrictions on the data shown an specific card, despite the page where the card is finally used and even if the card is used standalone.
Talking about usage, card filters are almost the same as page filters. They differ in the implications because:
A page filter can be applied on a particular card or not, depending on configuration.
A card filter will always be applied to that particular card.
Used together, both types of filters can be visually identified in Biuwer as the following example shows.
