bqplot.interacts.Interaction

class bqplot.interacts.Interaction(**kwargs)

The base interaction class.

An interaction is a mouse interaction layer for a figure that requires the capture of all mouse events on the plot area. A consequence is that one can allow only one interaction at any time on a figure.

An interaction can be associated with features such as selection or manual change of specific mark. Although, they differ from the so called ‘mark interactions’ in that they do not rely on knowing whether a specific element of the mark are hovered by the mouse.
