fastplotlib.LinearSelector

class LinearSelector(selection, limits, axis='x', parent=None, end_points=None, arrow_keys_modifier='Shift', thickness=2.5, color='w', name=None)

Create a horizontal or vertical line slider that is synced to an ipywidget IntSlider

Parameters:

• selection (int) – initial x or y selected position for the slider, in world space

• limits ((int, int)) – (min, max) limits along the x or y axis for the selector, in world space

• axis (str, default "x") – “x” | “y”, the axis which the slider can move along

• parent (Graphic) – parent graphic for this LineSelector

• end_points ((int, int)) – set length of slider by bounding it between two x-pos or two y-pos

• arrow_keys_modifier (str) – modifier key that must be pressed to initiate movement using arrow keys, must be one of: “Control”, “Shift”, “Alt” or None. Double click on the selector first to enable the arrow key movements, or set the attribute arrow_key_events_enabled = True

• color (Any, default "w") – selection to set the color of the slider

• name (str, optional) – name of line slider

Features

selection: LinearSelectionFeature

selection() returns the current selector position in world coordinates. Use get_selected_index() to get the currently selected index in data space. Use selection.add_event_handler() to add callback functions that are called when the LinearSelector selection changes. See feature class for event pick_info table
