The EditableFloatSlider widget allows selecting selecting a numeric floating-point value within a set bounds using a slider and for more precise control offers an editable number input box.

Parameters:#


For details on other options for customizing the component see the customization guides.

    • 

  • 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 (str, bokeh.models.TickFormatter): Formatter to apply to the slider value

    • 







Aliases#


For compatibility with Panel certain parameters are allowed as aliases:


    

  • button_style: Alias for variant
    • 

  • button_type: Alias for color
    • 

  • name: Alias for label
    • 











Basic Usage#


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


float_slider = pmui.EditableFloatSlider(
    label='EditableFloatSlider', start=0, end=3.141, step=0.01, value=1.57
)

float_slider








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


float_slider.value





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:


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

fixed_range












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.EditableFloatSlider(label='Distance', format='1[.]00')

tick_format = pmui.EditableFloatSlider(label='Distance', format=PrintfTickFormatter(format='%.3f m'))

pmui.Column(str_format, tick_format)












Label#


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


pmui.EditableFloatSlider()












Show Value#


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


pmui.EditableFloatSlider(show_value=False)












Disabled#


The widget can be disabled with disabled=True.


pmui.EditableFloatSlider(label='Float Slider (disabled)', disabled=True)












Color#


You can specify a color.


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












Sizes#


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


pmui.Row(
    pmui.EditableFloatSlider(label='Length Slider', size="small"),
    pmui.EditableFloatSlider(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.EditableFloatSlider(marks=marks)












Tooltip always visible#


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


pmui.EditableFloatSlider(label='Length', tooltips=True, value=42)












Tracks#


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


pmui.Row(
    pmui.EditableFloatSlider(label='Length Slider', value=42, track=False),
    pmui.EditableFloatSlider(label='Length Slider', value=42, track="inverted")
)












Vertical Sliders#


The orientation of a slider may be “vertical”:


pmui.EditableFloatSlider(label='Length Slider', value=42, orientation="vertical")












API Reference#


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


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