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 customization guides.

Core#

  • disabled (boolean): Whether the widget is editable

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

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

  • 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


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 = pmui.DatetimeRangeSlider(
    label='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))

Label#

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

pmui.DatetimeRangeSlider(start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14)))

Show Value#

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

pmui.DatetimeRangeSlider(
    start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
    value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14)),
    show_value=False, label='DatetimeRangeSlider'
)

Disabled#

The widget can be disabled with disabled=True.

pmui.DatetimeRangeSlider(
    label='Datetime Slider (disabled)', disabled=True,
    start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
    value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
)

Color#

You can specify a color.

pmui.FlexBox(*(
    pmui.DatetimeRangeSlider(
        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), dt.datetime(2019, 4, 14))
    )
    for color in pmui.DatetimeRangeSlider.param.color.objects
))

Sizes#

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

pmui.Row(
    pmui.DatetimeRangeSlider(
        label='Datetime Slider', size="small",
        start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
        value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
    ),
    pmui.DatetimeRangeSlider(
        label='Datetime Slider', size="medium",
        start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
        value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
    ),
)

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",
  }  
]

pmui.DatetimeRangeSlider(
    marks=marks, start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
    value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
)

Tooltip always visible#

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

pmui.DatetimeRangeSlider(
    label='Datetime Range', tooltips=True, start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1), value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
)

Tracks#

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

pmui.Row(
    pmui.DatetimeRangeSlider(
        label='Datetime Range Slider', track=False,
        start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
        value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
    ),
    pmui.DatetimeRangeSlider(
        label='Datetime Range Slider', track="inverted",
        start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
        value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
    )
)

Vertical Sliders#

The orientation of a slider may be “vertical”:

pmui.DatetimeRangeSlider(
    label='Datetime Range Slider', orientation="vertical",
    start=dt.datetime(2019, 1, 1), end=dt.datetime(2019, 6, 1),
    value=(dt.datetime(2019, 2, 8), dt.datetime(2019, 4, 14))
)

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:

pmui.Row(datetime_range_slider.api(jslink=True), datetime_range_slider)
