The DateRangeSlider widget allows selecting a date 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 layout and styling how-to guides.




Core#


    

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

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

  • step (int): Step in milliseconds, default is 1 minute (60.000 ms)
    • 

  • value (tuple): Tuple of upper and lower bounds of the selected range expressed as datetime types
    • 

  • value_throttled (tuple): Tuple of upper and lower bounds of the selected range expressed as datetime types throttled until mouseup
    • 







Display#


    

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

  • callback_policy (str, DEPRECATED): Policy to determine when slider events are triggered (one of ‘continuous’, ‘throttle’, ‘mouseup’)
    • 

  • callback_throttle (int): Number of milliseconds to pause between callback calls as the slider is moved
    • 

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

  • disabled (boolean): Whether the widget is editable
    • 

  • name (str): The title of the widget
    • 

  • orientation (str): Whether the slider should be displayed in a ‘horizontal’ or ‘vertical’ orientation.
    • 

  • tooltips (boolean): Whether to display tooltips on the slider handle
    • 





The slider start and end can be adjusted by dragging the handles and whole range can be shifted by dragging the selected range.


datetime_range_slider = pn.widgets.DatetimeRangeSlider(
    name='Datetime Range Slider',
    start=dt.datetime(2017, 1, 1), end=dt.datetime(2019, 1, 1),
    value=(dt.datetime(2017, 1, 1), dt.datetime(2018, 1, 10)),
    step=10000
)

datetime_range_slider








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


datetime_range_slider.value





(datetime.datetime(2017, 1, 1, 0, 0), datetime.datetime(2018, 1, 10, 0, 0))








Controls#


The DatetimeRangeSlider 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(datetime_range_slider.controls(jslink=True), datetime_range_slider)
