The GoInstruments for .NET library is a set of classes built to display numeric values in a graphical manner as part of GoDiagram for .NET applications.  The classes implement GoObjects that display a scale with regular markings and labels and they implement GoObjects that indicate a value on a scale.

The objects can be customized and combined to present many different kinds of appearances.  In the real world, depending on the industry, such things are called meters, dials, or gauges.  Because there is so much customization that can be done, GoInstruments does not provide any prebuilt instruments.  The InstrumentDemo sample application, however, does define many such objects for various purposes and with various appearances and behaviors.
