GoDiagram - Instruments

The Instruments library for GoDiagram is a set of classes built to display numeric values in a graphical manner as part of GoDiagram applications. The classes implement scale objects that display a scale with regular markings and labels and they implement indicator objects 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, rulers 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.

The code includes an InstrumentDemo sample application (shown above). The InstrumentDemo application also makes all of the object properties visible by means of a PropertyGrid control.

One of the advantages of Instruments is that it is part of a larger environment that supports graphics other than the instruments themselves, making it possible to add the instruments to a more complicated diagram.

An excellent component choice for building SCADA and industrial monitoring applications, featuring double buffered output to eliminate filcker.
