Use Attribute Filters on Dashboards
To filter your data by attributes, drag and drop Attribute filter to the filter bar at the top and select an attribute from the dropdown menu.
To change the order of the filters, drag a filter to a new position in the filter bar.
Filters that you use on dashboards do not override attribute filters in the visualizations.
If the attribute has any empty (NULL) values, you can include them in the filter as well by selecting empty value in the filter definition.
