Gauge (Control)

[ ]
When the value of the gauge cannot be directly changed, use a zero-width slider arm. Fill the track between the position of the minimum value and the current value to achieve a thermometer-like effect.

[ ]
When the value of the gauge can be directly changed, do the following:

  1. Use a slider arm whose appearance provides some indication (such as a thumb or handle) that it can be manipulated.

  2. Fill the track between the position of the minimum value and the slider arm to achieve a thermometer-like effect.

  3. Use the same pattern or color in the trough as in the slider arm so that they appear to be one continuous whole.

  4. Place the slider arm so that the edge opposite to the filled area is at the position of the current value.

    5. [ ]
    Do not display arrow buttons in a gauge if the value in the gauge cannot be changed.

    [ ]
    All appropriate guidelines that apply to sliders apply to gauges whose values can be directly changed by the user.
