In a radio button filter, each value is represented by a radio button.
The radio buttons are mutually exclusive, that is, only one of the alternatives in the filter can be set at a time. However, an (All) option is always present, letting you select all values. A (None) option is also available, letting you filter out all the values, showing nothing. If there are empty values present, a radio button named (Empty) will be available. Selecting this radio button will filter to the empty values.
Values that have been filtered out by other filters are indicated with gray text. If you select a radio button that is grayed out, nothing will be shown in the visualizations since that value has been filtered out already.
When the filter is active, you can use the arrow keys on the keyboard to change the selected radio button.
For columns containing more than 500 values, radio buttons cannot be used as the filter type.
