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)
