bqplot.interacts.MultiSelector¶

class bqplot.interacts.MultiSelector(**kwargs)[source]¶

Multi selector interaction.

This 1-D selector interaction enables the user to select multiple intervals using the mouse. A mouse-down marks the start of the interval. The drag after the mouse down in the x-direction selects the extent and a mouse-up signifies the end of the interval.

The current selector is highlighted with a green border and the inactive selectors are highlighted with a red border.

The multi selector has three modes:

default mode: In this mode the interaction behaves exactly as the

brush selector interaction with the current selector.
add mode: In this mode a new selector can be added by clicking at

a point and dragging over the interval of interest. Once a new selector has been added, the multi selector is back in the default mode. From the default mode, ctrl+click switches to the add mode.
choose mode: In this mode, any of the existing inactive selectors

can be set as the active selector. When an inactive selector is selected by clicking, the multi selector goes back to the default mode. From the default mode, shift+click switches to the choose mode.

A double click at the same point without moving the mouse in the x-direction will result in the entire interval being selected for the current selector.

selected¶

A dictionary with keys being the names of the intervals and values being the two element arrays containing the start and end of the interval selected by that particular selector in terms of the scale of the selector. This is a read-only attribute. This attribute changes while the selection is being made with the MultiSelectorinteraction.

Type:	dict

brushing¶

A boolean attribute to indicate if the selector is being dragged. It is True when the selector is being moved and false when it is not. This attribute can be used to trigger computationally intensive code which should be run only on the interval selection being completed as opposed to code which should be run whenever selected is changing.

Type:	bool (default: False)

names¶

A list of strings indicating the keys of the different intervals. Default values are ‘int1’, ‘int2’, ‘int3’ and so on.

Type:	list

show_names¶

Attribute to indicate if the names of the intervals are to be displayed along with the interval.

Type:	bool (default: True)
