public class Gauge extends DrawPane
The Gauge widget class implements a graphical speedometer-style gauge for displaying a measurement by means of a needle on a dial. The dial is divided into sectors, each having its own color and value.

NOTE: you must load the standard Drawing module before you can use Gauge.

  - ### setDefaultProperties

    public static void setDefaultProperties(Gauge gaugeProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `gaugeProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`

  - ### onInit

  - ### formatLabelContents

    protected String formatLabelContents(float value)
    Formats a value as a string to be used as the contents of a `DrawLabel`. The default implementation prepends `labelPrefix` and appends `labelSuffix` to `value`.

    NOTE: This is an override point. If a subclass overrides this, then whenever it changes the way that values are formatted, it should call `Gauge.reformatLabelContents`.

    Parameters:
      `value` - the value to format.
    Returns:
      label contents.

  - ### getDefaultFillColor

    protected String getDefaultFillColor(int sectorIndex)
    Gets the default fill color for the sector at index `sectorIndex`. The default implementation cycles through `sectorColors` using modular arithmetic.

    Note: This is an override point.

    Parameters:
      `sectorIndex` - index of the target sector.
    Returns:
      a fill color.
