The EditableRangeSlider widget allows selecting an integer range using a slider with two handles and two input boxes to manually adjust the range.

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
    • 











Basic Usage#


The EditableRangeSlider widget allows selecting a floating point range tuple in a range defined by the start and end values:


range_slider = pmui.EditableRangeSlider(
    label='Editable Slider', start=0, end=3.141, step=0.01, value=(0, 1.57)
)

range_slider








The value of the widget is returned as a tuple of floats and can be accessed and set like any other widget:


range_slider.value





(0, 1.57)






Fixed Range#


The slider is bounded by the start and end values but the text input fields can exceed end and go below start. If value should be fixed to a certain range it can be set with fixed_start and fixed_end:


pmui.EditableRangeSlider(
    label='Fixed Range', start=0, end=3.141, step=0.01, value=(0, 1.57), fixed_start=-3.14, fixed_end=6.282
)












Format#


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


from bokeh.models.formatters import PrintfTickFormatter

str_format = pmui.EditableRangeSlider(label='Distance', format='1[.]00')

tick_format = pmui.EditableRangeSlider(label='Distance', format=PrintfTickFormatter(format='%.2f m'), width=400)

pmui.Column(str_format, tick_format)












Label#


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


pmui.EditableRangeSlider()












Show Value#


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


pmui.EditableRangeSlider(show_value=False)












Disabled#


The widget can be disabled with disabled=True.


pmui.EditableRangeSlider(label='Range Slider (disabled)', disabled=True)












Color#


You can specify a color.


pmui.FlexBox(*(
    pmui.EditableRangeSlider(label=f'Range Slider ({color})', color=color)
    for color in pmui.EditableRangeSlider.param.color.objects
))












Sizes#


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


pmui.Row(
    pmui.EditableRangeSlider(label='Length Slider', size="small"),
    pmui.EditableRangeSlider(label='Length Slider', size="medium"),
)












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": 0,
    "label": '0°C',
  },
  {
    "value": 30,
    "label": '30°C',
  },
  {
    "value": 60,
    "label": '60°C',
  },
  {
    "value": 100,
    "label": '100°C',
  },
]

pmui.EditableRangeSlider(marks=marks)












Tooltip always visible#


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


pmui.EditableRangeSlider(label='Length', tooltips=True, value=(53.2, 91.3))












Tracks#


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


pmui.Row(
    pmui.EditableRangeSlider(label='Length Slider', value=(53.2, 91.3), track=False),
    pmui.EditableRangeSlider(label='Length Slider', value=(53.2, 91.3), track="inverted")
)












Vertical Sliders#


The orientation of a slider may be “vertical”:


pmui.EditableRangeSlider(label='Length Slider', value=(53.2, 91.3), orientation="vertical")












API Reference#


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


pmui.EditableRangeSlider().api(jslink=True)
