The RangeSlider widget allows selecting a floating-point range using a slider with two handles.

Discover more on using widgets to add interactivity to your applications in the how-to guides on interactivity. Alternatively, learn how to set up callbacks and (JS-)links between parameters or how to use them as part of declarative UIs with Param.

Parameters:#

For details on other options for customizing the component see the customization guides.

Core#

  • disabled (boolean): Whether the widget is editable

  • end (float): The range’s upper bound

  • start (float): The range’s lower bound

  • step (float): The interval between values

  • value (tuple): Tuple of upper and lower bounds of selected range

  • value_throttled (tuple): Tuple of upper and lower bounds of selected range throttled until mouseup

Display#

  • bar_color (color): Color of the slider bar as a hexadecimal RGB value.

  • direction (str): Whether the slider should go from left to right (‘ltr’) or right to left (‘rtl’).

  • format (string): The datetime’s format

  • label (str): The title of the widget.

  • marks (boolean | list[dict]): Marks indicate predetermined values to which the user can move the slider. If True the options are shown as marks. If a list, it should contain dicts with ‘value’ and an optional ‘label’ keys.

  • orientation (Literal["horizonta", "vertical"]): Whether the slider should be displayed in a ‘horizontal’ or ‘vertical’ orientation.

  • show_value (boolean): Whether to show the widget value as a label or not.

  • tooltips (boolean | Literal["auto"]): Whether to display tooltips on the slider handle.

  • track (Literal["normal", "inverted"]): Whether to display ‘normal’ or ‘inverted’.

Styling#

  • sx (dict): Component level styling API.

  • theme_config (dict): Theming API.

Aliases#

For compatibility with Panel certain parameters are allowed as aliases:

  • name: Alias for label


range_slider = pmui.RangeSlider(
    name='Range Slider', start=0, end=math.pi, value=(math.pi/4., math.pi/2.), step=0.01)

range_slider

RangeSlider.value returns a tuple of float values that can be read out and set like other widgets:

range_slider.value
(0.7853981633974483, 1.5707963267948966)

A custom format string or bokeh TickFormatter may be used to format the slider values:

from bokeh.models.formatters import PrintfTickFormatter

str_format = pmui.RangeSlider(name='Distance', format='0.0a', start=100000, end=1000000)

tick_format = pmui.RangeSlider(name='Distance', format=PrintfTickFormatter(format='%.3f m'))

pn.Column(str_format, tick_format)

Controls#

The RangeSlider widget exposes a number of options which can be changed from both Python and Javascript. Try out the effect of these parameters interactively:

pn.Row(range_slider.controls(jslink=True), range_slider)
