represents a slider with setting x in the range 0 to 1.


takes the setting to be the dynamically updated current value of x, with the value of x being reset if the slider is moved.


represents a slider with range xmin to xmax.


represents a slider that jumps in steps dx.


represents a slider in which equally spaced intervals correspond to successive settings ei.


uses intervals of relative widths wi for the ei.

Details and Options

  • Slider[] displays in a notebook as a horizontal slider that can be manipulated interactively.
  • Slider[Dynamic[x]] will reset the value of x when the slider is moved; Slider[x] will not.
  • Slider[n,{nmin,nmax,dn}] jumps to integer positions if nmin and dn are integers. »
  • Slider[x,{xmin,xmax,dx}] in general jumps to positions given by Range[xmin,xmax,dx]. »
  • Slider[x] represents a slider running from left to right.
  • Slider[x,{xmax,xmin}] with xmax > xmin represents a slider running from right to left. »
  • If the value of the slider is outside the range given, it will be displayed at one of the ends.
  • Slider[x,{0,1,dx}] displays at position x, even if this is not a multiple of dx.
  • In Slider[x,{{e1,e2,}}], the ei can be any expressions, not just numbers. »
  • The following options can be given:
  • AppearanceAutomaticthe overall appearance of the slider
    AutoActionFalsewhether to move the slider automatically when the mouse is over it
    BaselinePositionAutomaticalignment relative to surrounding text
    BaseStyle{}base style specifications for the slider
    ContinuousActionTruewhether to update continuously when the slider is moved
    EnabledAutomaticwhether the slider is enabled or grayed out
    Exclusions{}specific values to be excluded
    ImageMargins0margins around the image of the displayed slider
    ImageSizeAutomaticthe overall image size of the displayed slider
  • Possible settings for Appearance include Tiny, Small, Medium, and Large, as well as typically some other settings such as "UpArrow" and "DownArrow".
  • Appearance->"Labeled" displays the current value of the slider as an editable label.
  • The settings for BaseStyle are appended to the default style typically given by the "Slider" style in the current stylesheet.
  • Slider[] is equivalent to Slider[0.5].
  • The resulting slider can be finely manipulated by holding down the key (or on Macintosh) while dragging the mouse. This causes the slider to move at 1/20 the rate of the mouse. The slider can be even more finely manipulated by also holding the and/or keys.

Options  (20)

Appearance  (4)

Different sizes:

Add a label:

Special arrow appearances are available on some platforms:

Use dynamic appearance, based on whether Round[x] is or :

AutoAction  (2)

By default, no slider values change until you click in the slider area:
