bqplot.interacts.FastIntervalSelector¶

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

Fast interval selector interaction.

This 1-D selector is used to select an interval on the x-scale by just moving the mouse (without clicking or dragging). The x-coordinate of the mouse controls the mid point of the interval selected while the y-coordinate of the mouse controls the the width of the interval. The larger the y-coordinate, the wider the interval selected.

Interval selector has three modes:

default mode: This is the default mode in which the mouse controls

the location and width of the interval.
fixed-width mode: In this mode the width of the interval is frozen

and only the location of the interval is controlled with the mouse. A single click from the default mode takes you to this mode. Another single click takes you back to the default mode.
frozen mode: In this mode the selected interval is frozen and the

selector does not respond to mouse move. A double click from the default mode takes you to this mode. Another double click takes you back to the default mode.

selected¶

Two-element array containing the start and end of the interval selected in terms of the scale of the selector.

Type:	numpy.ndarray

color¶

color of the rectangle representing the interval selector

Type:	Color or None (default: None)

size¶

if not None, this is the fixed pixel-width of the interval selector

Type:	Float or None (default: None)
