Sliders

Overview

Sliders select a numeric value or range of values by moving a handle or set of handles along a bar. They are ideal for adjusting settings such as volume and brightness. The slider in its basic form should be accompanied by a label and a number input that doubles as a display for the slider’s current value.

Usage

Use when

• Encouraging user exploration when setting a value or range of values, especially when that value has an immediate effect on a data visualization.
• A series of options is presented using a stepped slider.

Don’t use when

• Gathering information in a form (e.g, age or salary). Instead, use an Input box.
• Precise amount is needed and the scale is too large to afford precise interaction with the slider.
• Adjusting settings with any delay in providing user feedback.

Types

Continuous Sliders

Continuous sliders allow users to make selections along a subjective range thus don’t require a specific value.

Discrete Sliders

Discrete sliders display a numeric value label upon dragging the handle, or allow users to input an exact value. Tick marks are also often used with discrete slides but are optional.
