A Dial represents a value in some range as a position on an annular dial. It is similar to a Gauge but more minimal visually.

Use pn.ui.Dial to create this component.

value = Number(allow_None=True, default=25, inclusive_bounds=(True, True), label='Value')

  Value to indicate on the dial a value within the declared bounds.

height = Integer(allow_None=True, bounds=(1, None), default=250, inclusive_bounds=(True, True), label='Height')

    The height of the component (in pixels).  This can be either
    fixed or preferred height, depending on height sizing policy.

width = Integer(allow_None=True, bounds=(1, None), default=250, inclusive_bounds=(True, True), label='Width')

    The width of the component (in pixels). This can be either
    fixed or preferred width, depending on width sizing policy.

annulus_width = Number(default=0.2, inclusive_bounds=(True, True), label='Annulus width')

  Width of the radial annulus as a fraction of the total.

background = Parameter(allow_None=True, label='Background')

    Background color of the component.

bounds = Range(default=(0, 100), inclusive_bounds=(True, True), label='Bounds', length=2)

  The upper and lower bound of the dial.

colors = List(allow_None=True, bounds=(0, None), item_type=<class 'tuple'>, label='Colors')

  Color thresholds for the Dial, specified as a list of tuples
  of the fractional threshold and the color to switch to.

default_color = String(default='lightblue', label='Default color')

  Color of the radial annulus if not color thresholds are supplied.

end_angle = Number(default=25, inclusive_bounds=(True, True), label='End angle')

  Angle at which the dial ends.

format = String(default='{value}%', label='Format')

  Formatting string for the value indicator and lower/upper bounds.

label_color = String(default='black', label='Label color')

  Color for all extraneous labels.

nan_format = String(default='-', label='Nan format')

  How to format nan values.

needle_color = String(default='black', label='Needle color')

  Color of the Dial needle.

needle_width = Number(default=0.1, inclusive_bounds=(True, True), label='Needle width')

  Radial width of the needle.

start_angle = Number(default=-205, inclusive_bounds=(True, True), label='Start angle')

  Angle at which the dial starts.

tick_size = String(allow_None=True, label='Tick size')

  Font size of the Dial min/max labels.

title_size = String(allow_None=True, label='Title size')

  Font size of the Dial title.

unfilled_color = String(default='whitesmoke', label='Unfilled color')

  Color of the unfilled region of the Dial.

value_size = String(allow_None=True, label='Value size')

  Font size of the Dial value label.
