Aliases#


For compatibility with Panel certain parameters are allowed as aliases:

    • 





datetime_slider = pn.ui.DatetimeSlider(
    label='Datetime Slider', start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8, 15, 40, 30)
)

datetime_slider







            
            
DatetimeSlider.value returns a datetime type that can be read out or set like other widgets:


datetime_slider.value





datetime.datetime(2019, 2, 8, 15, 40, 30)








Label#


You may remove the label/ name by not setting it.


pn.ui.DatetimeSlider(start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8))







            
            




Show Value#


You may remove the value label by setting show_value=False.


pn.ui.DatetimeSlider(start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8), show_value=False, label='DatetimeSlider')







            
            




Disabled#


The widget can be disabled with disabled=True.


pn.ui.DatetimeSlider(label='Datetime Slider (disabled)', disabled=True, start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8))







            
            




Color#


You can specify a color.


pn.ui.FlexBox(*(
    pn.ui.DatetimeSlider(label=f'Datetime Slider ({color})', color=color, start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8))
    for color in pn.ui.DatetimeSlider.param.color.objects
))







            
            




Sizes#


For smaller slider, use the parameter size="small".


pn.ui.Row(
    pn.ui.DatetimeSlider(label='Datetime Slider', size="small", start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8)),
    pn.ui.DatetimeSlider(label='Datetime Slider', size="medium", start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8)),
)







            
            




Custom Marks#


You can have custom marks by providing a rich list to the marks parameter. Note that unlike continuous sliders the value of the marks should be the integer index of the option.


marks = [
  {
    "value": dt.datetime(2019, 1, 1),
    "label": "01/01",
  },
  {
    "value": dt.datetime(2019, 3, 1),
    "label": "03/01",
  },
  {
    "value": dt.datetime(2019, 5, 1),
    "label": "05/01",
  },
  {
    "value": dt.datetime(2019, 6, 1),
    "label": "06/01",
  }  
]

pn.ui.DatetimeSlider(marks=marks, start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8))







            
            




Tooltip always visible#


You can force the thumb label to be always visible with tooltips=True.


pn.ui.DatetimeSlider(
    label='Date', tooltips=True, start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8)
)







            
            




Tracks#


The track can be inverted or removed with track="inverted" and track=False respectively:


pn.ui.Row(
    pn.ui.DatetimeSlider(label='Datetime Slider', track=False, start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8)),
    pn.ui.DatetimeSlider(label='Datetime Slider', track="inverted", start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8))
)







            
            




Vertical Sliders#


The orientation of a slider may be “vertical”:


pn.ui.DatetimeSlider(label='Datetime Slider', orientation="vertical", start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=dt.datetime(2019, 2, 8))







            
            




Icon Labels#


Material icon tokens like :material/zoom_out_map: render as icons in labels and option labels.


icon_datetime_slider = pn.ui.DatetimeSlider(
    label=":material/schedule: Window",
    start=dt.datetime(2019, 1, 1),
    end=dt.datetime(2019, 6, 1),
    value=dt.datetime(2019, 2, 8),
)

icon_datetime_slider







            
            




Controls#


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


pn.ui.Row(datetime_slider.api(jslink=True), datetime_slider)
