The FloatSlider widget allows selecting selecting a numeric floating-point value within a set bounds using a slider.


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 (float): The selected value as a float type
    • 

  • value_throttled (float): The selected value as a float type 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
    • 





float_slider = pmui.FloatSlider(name='Float Slider', start=0, end=3.141, step=0.01, value=1.57)

float_slider







            
            
The FloatSlider value is returned as a float and can be accessed and set like any other widget:


float_slider.value





1.57


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


from bokeh.models.formatters import PrintfTickFormatter

str_format = pmui.FloatSlider(name='Distance', format='1[.]00')

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

pn.Column(str_format, tick_format)







            
            






Controls#


The FloatSlider 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(float_slider.controls(jslink=True), float_slider)
