A filter is a set of characteristics or conditions that, when applied, removes specific values from the original data in an Visualization. Filters allow you to narrow the scope of a visualization without changing the visualization itself.
You can create filters based on attribute values, metric values, or dates. For example, if you have a visualization showing the sold products with their prices, you may want to display the data only for a specific period (such as last month or previous year; that is, apply a date filter) or to display the data only for a specific product (that is, apply an attribute filter).
