altair.selection

altair.selection(type=Undefined, **kwds)

Users are recommended to use either ‘selection_point’ or ‘selection_interval’ instead, depending on the type of parameter they want to create.

Create a selection parameter.

Parameters:

typeenum(‘point’, ‘interval’) (required)

Determines the default event processing and data query for the selection. Vega-Lite currently supports two selection types: * “point” - to select multiple discrete data values; the first value is selected on click and additional values toggled on shift-click. * “interval” - to select a continuous range of data values on drag.

**kwds

additional keywords to control the selection.
